  • Overload and hide methods in Java

    - by Marco
    Hi, i have an abstract class BaseClass with a public insert() method: public abstract class BaseClass { public void insert(Object object) { // Do something } } which is extended by many other classes. For some of those classes, however, the insert() method must have additional parameters, so that they instead of overriding it I overload the method of the base class with the parameters required, for example: public class SampleClass extends BaseClass { public void insert(Object object, Long param){ // Do Something } } Now, if i instantiate the SampleClass class, i have two insert() methods: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object); sampleClass.insert(Object object, Long param); what i'd like to do is to hide the insert() method defined in the base class, so that just the overload would be visible: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object, Long param); Could this be done in OOP?

  • String generator issue

    - by Andrey
    I want to write a method which returns a string. So far so good. The creation of the string however is quite complicated. I have 3 string lists - the first one has 155 entries, the second one - 9, the third one 21. I want my method if called enough times(155*9*21) to return all the possible combinations of values from the 3 lists (basically this method should keep count on how many times it was called and return only one combination each time). Any ideas how to accomplish that? I have 155*9*22 possible combinations. The first time the method is called it should take List1(0), List2(0), List3(0). After that in the next 21 iterations, the index of the third list is only changed. Once all the elements from the third list have been used increment the index of the second list and so on. Once the method has produced all the possible combinations (155*9*22) I want it to start from the beginning.

  • Is there a way to inspect all controller variables at once in Rails?

    - by m.u.sheikh
    I am exploring an big controller method, with about 10 or so instance variables. Some of them are set in before_filter methods, and some others inside the method itself. I want to inspect them with puts, but dont want to write all of them out example: puts "var1: #{@var1.inspect}....var15: #{@var15.inspect}" Is there a generic method that will display all the instance variables with an @ sign set so far in the current method? If not, what is the next best way to inspect all of them at once without having to write all of them in a puts statement?

  • How to trigger the specific controller action using a button?

    - by Eugene
    I'm creating a simple training project. I've implemented a controller method, which deletes an item from the list. The method is looking like this: @Controller @RequestMapping(value = "/topic") public class TopicController { @Autowired private TopicService service; ... @RequestMapping(value = "/deleteComment/{commentId}", method = RequestMethod.POST) public String deleteComment(@PathVariable int commentId, BindingResult result, Model model){ Comment deletedComment = commentService.findCommentByID(commentId); if (deletedComment != null) { commentService.deleteComment(deletedComment); } return "refresh:"; } } This method is called from the button-tag, which is looking in the following way: _form> _button formaction = "../deleteComment/1" formmethod = "post">delete_/button> _/form> Sorry, but in the form tag I've changed all the '<' characters with the '_', because the tag was invisible. In my project the form-tag is looking like a cliuckable button. But there is a serious problem: controller's method is never triggered. How can I trigger it, using a button-tag? P.S. the call is performed from the page with URI http://localhost:8080/simpleblog/topic/details/2 and controller's URI is the http://localhost:8080/simpleblog/topic/deleteComment/2

  • Templates, Function Pointers and C++0x

    - by user328543
    One of my personal experiments to understand some of the C++0x features: I'm trying to pass a function pointer to a template function to execute. Eventually the execution is supposed to happen in a different thread. But with all the different types of functions, I can't get the templates to work. #include `<functional`> int foo(void) {return 2;} class bar { public: int operator() (void) {return 4;}; int something(int a) {return a;}; }; template <class C> int func(C&& c) { //typedef typename std::result_of< C() >::type result_type; typedef typename std::conditional< std::is_pointer< C >::value, std::result_of< C() >::type, std::conditional< std::is_object< C >::value, std::result_of< typename C::operator() >::type, void> >::type result_type; result_type result = c(); return result; } int main(int argc, char* argv[]) { // call with a function pointer func(foo); // call with a member function bar b; func(b); // call with a bind expression func(std::bind(&bar::something, b, 42)); // call with a lambda expression func( [](void)->int {return 12;} ); return 0; } The result_of template alone doesn't seem to be able to find the operator() in class bar and the clunky conditional I created doesn't compile. Any ideas? Will I have additional problems with const functions?

  • The HTTP verb POST used to access path '[my path]' is not allowed.

    - by Jed
    I am receiving an error that states: "The HTTP verb POST used to access path '[my path]' is not allowed.". The error is being caused by the fact that I am implementing an HTML form element that uses the POST method and does not explicitly define an .aspx page in its ACTION parameter. For example: <form action="" method="post"> <input type="submit" /> </form> The HTML above is on a file at "/foo/default.aspx". Now, if the user points the URL to the root directory "foo" without specifying the aspx file (i.e. "http://localhost/foo") and then submits the form, the error "The HTTP verb POST used to access path '/foo' is not allowed." will be thrown. However, if the user goes to "http://localhost/foo/default.aspx" and then submits the form, all goes well (even if the ACTION parameter is left empty). Note: If I explicitly add the name of the .aspx (default.aspx) page to the ACTION parameter, no errors are thrown. So the example below works fine regardless if the user defines the name of the file in the URL or not. <form action="default.aspx" method="post"> <input type="submit" /> </form> I was curious as to why the error was being thrown, so I read a Microsoft KB that states This problem occurs because a client makes an HTTP request by sending the POST method to a static HTML page. Static HTML pages do not support the POST method. I suppose the core of the explanation makes sense, however in my case, my form is not being sent to a static html page - it's being sent to the same page that the html form lives on (default.aspx)... this is implicit to an ACTION param that is left empty. Is it possible to configure IIS (or otherwise) that will allow us to do form POSTing and keep the ACTION param empty?

  • [MSBuild] Problem with setting properties 's values.

    - by Nam Gi VU
    Let's consider the below example. There, I have: target MAIN call target t then call target tt. target t call target ttt, target tt call target tttt. target t define property aa, target ttt modify aa. target tttt try to print property aa 's value. in short we have: MAIN - {t - {ttt-modify aa, define aa}, tt - tttt - print aa} But in target tttt, we can't "see" aa's updated value (by ttt)! Please help me to make that value visible to target tttt. Thank you! The whole script is as below: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="MAIN" > <Target Name="MAIN" > <CallTarget Targets="t" /> <CallTarget Targets="tt" /> </Target> <Target Name="t"> <Message Text="t" /> <PropertyGroup> <aa>1</aa> </PropertyGroup> <CallTarget Targets="ttt" /> </Target> <Target Name="tt"> <Message Text="tt" /> <CallTarget Targets="tttt" /> </Target> <Target Name="ttt"> <PropertyGroup> <aa>122</aa> </PropertyGroup> <Message Text="ttt" /> </Target> <Target Name="tttt"> <Message Text="tttt" /> <Message Text="tttt:$(aa)" /> </Target> </Project>

  • Java Thread Message Passing

    - by pkulak
    I'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something? Here's some code about what I'm talking about: public class Mealfire extends Activity { @Override public void onCreate(Bundle icicle) { (new Thread() { public void run() { // Do a bunch of slow network stuff. update(); } }).start(); } private void update() { myAdapter.notifyDatasetChanged(); } }

  • jQuery/Ajax IE7 - Long requests fail

    - by iQ
    Hi guys, I have a problem with IE7 regarding an ajax call that is made by jQuery.load function. Basically the request works in cases where the URL string is not too long, but as soon as the URL gets very large it fails. Doing some debugging on the Ajax call I found this error: URL: <blanked out security reasons but it's very long> Content Type: Headers size (bytes): 0 Data size (bytes): 0 Total size (bytes): 0 Transferred data size (bytes): 0 Cached data: No Error result: 0x800c0005 Error constant: INET_E_RESOURCE_NOT_FOUND Error description: The server or proxy was not found Extended error result: 0x7a Extended error description: The data area passed to a system call is too small. As you can see, it looks like nothing is being sent. Now this only happens on IE7 but not other browsers, with IE8 there is a small delay but still works. The same request works fine when the URL string is relatively small. Now I need this working on IE7 for compatibility reasons and I cannot find workarounds for this so any help is greatly appreciated. The actual ajax call is like this: $("ID").load("url?lotsofparams",callbac func(){}); "lotsofparams" can vary, sometimes being small or very large. It's when the string is very large that I get the above error for IE7 only.

  • In Java, can a final field be initialized from a constructor helper?

    - by csj
    I have a final non-static member: private final HashMap<String,String> myMap; I would like to initialize it using a method called by the constructor. Since myMap is final, my "helper" method is unable to initialize it directly. Of course I have options: I could implement the myMap initialization code directly in the constructor. MyConstructor (String someThingNecessary) { myMap = new HashMap<String,String>(); myMap.put("blah","blahblah"); // etc... // other initialization stuff unrelated to myMap } I could have my helper method build the HashMap, return it to the constructor, and have the constructor then assign the object to myMap. MyConstructor (String someThingNecessary) { myMap = InitializeMyMap(someThingNecessary); // other initialization stuff unrelated to myMap } private HashMap<String,String> InitializeMyMap(String someThingNecessary) { HashMap<String,String> initializedMap = new HashMap<String,String>(); initializedMap.put("blah","blahblah"); // etc... return initializedMap; } Method #2 is fine, however, I'm wondering if there's some way I could allow the helper method to directly manipulate myMap. Perhaps a modifier that indicates it can only be called by the constructor? MyConstructor (String someThingNecessary) { InitializeMyMap(someThingNecessary); // other initialization stuff unrelated to myMap } // helper doesn't work since it can't modify a final member private void InitializeMyMap(String someThingNecessary) { myMap = new HashMap<String,String>(); myMap.put("blah","blahblah"); // etc... }

  • How to peform an external request in Kohana 3?

    - by alex
    I've always used cURL for this sort of stuff, but this article got me thinking I could request another page easily using the Request object in Kohana 3. $url = 'http://www.example.com'; $update = Request::factory($url); $update->method = 'POST'; $update->post = array( 'key' => 'value' ); $update->execute(); echo $update->response; However I get the error Accessing static property Request::$method as non static From this I can assume it means that the method method is static, but that doesn't help me much. I also copied and pasted the example from that article and it threw the same error. Basically, I'm trying to POST to a new page on an external server, and do it the Kohana way. So, am I doing this correctly, or should I just use cURL (or file_get_contents() with context)?

  • Can a second stored procedure doing the same thing finish before first one?

    - by evanmortland
    Hello, I have an audit record table that I am writing to. I am connecting to MyDb, which has a stored procedure called 'CreateAudit', which is a passthrough stored procedure to another database on the same machine called 'CreatedAudit' as well. I call the CreateAudit stored procedure from my application, using subsonic as the DAL. The first time I call it, I call it with the following (pseudocode): Result = CreateAudit(recordId, "Opened") Right after that, I call: Result2 = CreateAudit(recordId, "Closed") In my second stored procedure it is supposed to mark the record that was created by the CreateAudit(recordId, "Opened") with a status of closed. It works great if I run them independently of one another, but when they run in sequence in the application, the record is not marked as "Closed". When I run SQL profiler I see that both queries ran, and if I copy the queries out and run them from query analyzer the record gets marked as closed 100% of the time! When I run it from the application, about once every 20 times or so, the record is successfully marked closed - the other 19 times nothing happens, but I do not get an error! Is it possible for the .NET app to skip over the ouput from the first stored procedure and start executing the second stored procedure before the record in the first is created? When I add a "WAITFOR DELAY '00:00:00:003'" to the top of my stored procedure, the record is also closed 100% of the time. My head is spinning, any ideas why this is happening! Thanks for any responses, very interested in hearing how this can happen.

  • Javascript - Wait for function to return

    - by LoadData
    So, I am working on a project which requires me to call upon a function to get data from an external source. The issue I am having, I call upon the function - However the code after the function call is continuing before the function has returned a value. Here is the function - function getData() { var myVar; var xmlLoc = $.get("http://ec.urbentom.co.uk/StudentAppData.xml", function(data) { $xml = $(data); myVar = $xml; console.log(myVar); console.log(String($xml)); localStorage.setItem("Data", $xml); console.log(String(localStorage.getItem("Data"))); return myVar; }); return myVar; console.log("Does this continue"); } And here is where it is called upon - $(document).on("pageshow","#Information",function() { $xml = $(getData()); //Here is the function call console.log($xml); //However, it will instantly go to this line before 'getData' has returned a value. $xml.find('AllData').each(function() { $(this).find('item').each(function() { if ($(this).find('Category').text()=="Facilities") { console.log($(this).find('Title').text()); //Do stuff here } else if ($(this).find('Category').text()=="Contacts" || $(this).find('Category').text()=="Information") { console.log($(this).find('Title').text()); //Do stuff here too } }); $('#informationList').html(output).listview().listview("refresh"); console.log("Finished"); }); }); Right now, I'm unsure of why it is not working. My guess is that it is because I am calling a function within a function. Does anyone have any ideas on how this issue can be fixed?

  • Need a design approach or suggestion for a simple structure using Servlet.

    - by akshay
    Hi I have to design such that whenever user pass a query I process it using servlet and then call the js page to draw the chart 1 user writes a query on a page 2 the page call the servelt class public class MyServlet extends Httpservlet implements DataSourceServlet {..... return data The user see a beautiful string like this.. google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); 3 when the user hits on different html page myhtml.js it draws the chart. I want the Myservlet class itself call the myhtml.js page and draw the chart directly. and want to eliminate the beautiful string google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); from coming on user's browser What should i do? I tried using functions to call another page like request dispatcher(), redirect() calling myhtml.js page directly after myservlet process the query results. But i get the result like this google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); and the entire myhtml.js code page below it on the browsers that to without the chart been draw. Is there anyway to element the beautiful string from coming on clients browser and only show them the chart been drawn ? :) This is the small tutorial i am following http://code.google.com/apis/visualization/documentation/dev/dsl_get_started.html

  • simplemodal click events stopped working in IE7

    - by prettynerd
    Here's my code: $('#alertInfo').modal({ close :false, overlayId :'confirmModalOverlay', containerId :'confirmModalContainer', onShow : function(dialog) { dialog.data.find('.message').append(message); dialog.data.find('.yes').click(function(){ if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); dialog.data.find('.close').click(function(){ $.modal.close(); }); } }); Basically, this is a dialogue box which I call to show a warning message that has a "X" button (with class 'close') and an "OK" button (with class 'yes'). The problem occurs in IE7. When I call this dialogue box and use my "X" button to close it everytime, my "X" button does not work anymore on the third time I call it (YES ON THE THIRD TIME!). However, if I use my "OK" button to close the dialogue box, it works fine no matter how many times I call it. I thought I found a workaround by unbinding and binding my click event of the '.close' class, as below: dialog.data.find('.close').unbind('click'); dialog.data.find('.close').bind('click',function(){$.modal.close();}); and it worked!!! unfortunately, however, the problem now occurs in my "OK" button. so, i did the same unbinding and binding the click event of the '.yes' class, as below: dialog.data.find('.yes').unbind('click'); dialog.data.find('.yes').bind('click', function() { if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); BUT NOPE, IT DOES NOT WORK.. please help me.. @ericmmartin, i hope you're online now.. huhu..

  • Usage of setInfoClass() on DirectoryIterator vs on RecursiveDirectoryIterator

    - by Gordon
    I've ran into an inconsistent behavior when using setInfoClass to set a custom SplFileInfo class to a DirectoryIterator versus setting it to a RecursiveIterator. The method description states: Use this method to set a custom class which will be used when getFileInfo and getPathInfo are called. The class name passed to this method must be derived from SplFileInfo. Consider this custom SplFileInfo class A extends SplFileInfo { public function test() { printf("I am of class %s\n", __CLASS__); } } and my iterators $iterator = new DirectoryIterator('.'); and $iterator = new RecursiveDirectoryIterator('.'); Now I'd expect those two to behave the same when I do $iterator->setInfoClass('A'); foreach($iterator as $file) { $file->test(); } and output 'I am of A' for each $file encountered and in fact, the RecursiveDirectoryIterator will do that. But the DirectoryIterator will raise Fatal error: Call to undefined method DirectoryIterator::test() so apparently the InfoClass does not get applied when iterating over the files. At least not directly, because when I change the code in the foreach loop to $file->getPathInfo()->test(); it will work for the DirectoryIterator. But then the RecursiveDirectoryIterator will raise Fatal error: Call to undefined method SplFileInfo::test() Like I said, I'd expect those two to behave the same, but apparently getFileInfo and getPathInfo don't get called in the DirectoryIterator, which I consider a bug. So if there is any Iterator experts out there, please help me understand this. Thanks.

  • problems piping in node.js

    - by alvaizq
    We have the following example in node.js var http = require('http'); http.createServer(function(request, response) { var proxy = http.createClient(8083, '127.0.0.1') var proxy_request = proxy.request(request.method, request.url, request.headers); proxy_request.on('response', function (proxy_response) { proxy_response.pipe(response); response.writeHead(proxy_response.statusCode, proxy_response.headers); }); setTimeout(function(){ request.pipe(proxy_request); },3000); }).listen(8081, '127.0.0.1'); The example listen to a request in 127.0.0.1:8081 and sends it to a dummy server (always return 200 OK status code) in 127.0.0.1:8083. The problem is in the pipe among the input stream (readable) and output stream (writable) when we have a async module before (in this case the setTimeOut timing). The pipe doesn't work and nothing is sent to dummy server in 8083 port. Maybe, when we have a async call (in this case the setTimeOut) before the pipe call, the inputstream change to a state "not readable", and after the async call the pipe doesn't send anything. This is just an example...we test it with more async modules from node.js community with the same result (ldapjs, etc)... We try to fix it with: - request.readable =true; //before pipe call - request.pipe(proxy_request, {end : false}); with the same result (the pipe doesn't work). Can anybody help us? Many thanks in advanced and best regards,

  • ASP .NET Dynamically adding EventHandlers to button on Page_Load. EventHandler's do not fire the fir

    - by John
    Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers are triggered. On the second click, they are triggered. Any ideas? Example of Button Definition Button btn = new Button(); btn.Text = "Click Me Locked Screen"; bth.Click += new EventHandler(Btn_Click); Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something }
