  • Enum : get the keys list

    - by Damien MATHIEU
    Hello, I'm not a java developer. But I'm currently taking a look at Android applications development so I'm doing a bit of nostalgy, doing some java again after not touching it for three years. I'm looking forward using the "google-api-translate-java" library. In which there is a Language class. It's an enum allowing to provide the language name and to get it's value for Google Translate. I can easily get all the values with : for (Language l : values()) { // Here I loop on one value } But what I'd want to get is a list of all the keys names (FRENCH, ENGLISH, ...). Is there something like a "keys()" method that'd allow me to loop through all the enum's keys ?

  • best way to filter out non-representational elements

    - by nonano
    Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

  • Filter---after setting attribute--->Servlet---after getting and setting the attribute---->Jsp How do I do this?

    - by Y.E.P
    This is what I want to do : A servlet is called.Before a servlet is called , the request is intercepted by a filter. Filter gets some details out from the request,sets them as an attribute and the forwards it to a servlet via chain.doFilter(request,response). Request finally reaches the servlet. Servlet gets the attribute set by the filter before and sets a new attribute by another name. Then it forwards it to some jsp page where the page gets the attribute and processes it. How do I do this ? I know how to write a filter and a servlet but how do I forward it to a jsp page from the servlet or is there any other way to achieve this ?

  • errorPage directive works, but error-page in web.xml doesn't?

    - by danb
    I get jsp exceptions causing a forward to my error page when I put this at the top of my JSPs... <%@ page errorPage="/error.page" %> but when I try to do it globally with web.xml like so: <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/error.page</location> </error-page> I just get a blank page... I've also tried putting /error.jsp in the location element.. but no love with that either.. I am triggering an exception with a jsp that just contains this: <%if(true)throw new RuntimeException("test exception");%> I do see the exception in the console from tomcat but I just can't get that error page to show without a directive on every jsp... am I missing something simple here?

  • Beginner: Best Practices in an Android App UI Navagation

    - by AndyD273
    I am trying to learn how to do stuff in Android, and I'm not sure of the best way to build the interface. I've been working on porting an iPhone app, which uses navigation controllers and table views for looking at the different sections: basically, someone touches a cell in the table, which drills down to another table. when they touch a cell on that table it drills down to a webview that displays the information. I want to do something similar for the android app, but I don't know how, or if there is a better way native to Android. I've figured out how to use the webview to my purposes, but moving forward and backward in the table tree is unclear.

  • Looping through a method without for/foreach/while

    - by RichK
    Is there a way of calling a method/lines of code multiple times not using a for/foreach/while loop? For example, if I were to use to for loop: int numberOfIterations = 6; for(int i = 0; i < numberOfIterations; i++) { DoSomething(); SomeProperty = true; } The lines of code I'm calling don't use 'i' and in my opinion the whole loop declaration hides what I'm trying to do. This is the same for a foreach. I was wondering if there's a looping statement I can use that looks something like: do(6) { DoSomething(); SomeProperty = true; } It's really clear that I just want to execute that code 6 times and there's no noise involving index instantiating and adding 1 to some arbitrary variable. As a learning exercise I have written a static class and method: Do.Multiple(int iterations, Action action) Which works but scores very highly on the pretentious scale and I'm sure my peers wouldn't approve. I'm probably just being picky and a for loop is certainly the most recognisable, but as a learning point I was just wondering if there (cleaner) alternatives. Thanks. (I've had a look at this thread, but it's not quite the same) http://stackoverflow.com/questions/2248985/using-ienumerable-without-foreach-loop

  • What does open source license (like GNU-GPL) mean?

    - by Hemant
    I am looking forward to use an open source product which has GNU-GPL like license and it says that if I use that product, I must share the source code of my application. I am slightly confused about it. I understand that Linux is available under GNU-GPL license as well. Does it mean ALL linux application are and has to be open source? Does it mean I can ask for the source code of complete Oracle DB from Oracle Corp (at least the part that runs on Linux)?

  • How to keep the first result of a function from Prolog?

    - by zuhakasa
    I need to write a customized function that will be called many times by other fixed functions. In this function, at the first called time, it will return the total number of lines of a file. The second called time of this function, forward, will return the number of lines in small sections of this file. My question is how I keep the first returned result(total number of lines of a file) and use it for the next called times of my function. I need to write or declare any thing only in this function(not in the caller). Something like this: myFunction(Input, MyResult, FirstResult) :- calculateInputFunction(Input, Result), !, MyResult is Result, ... . The problem is, every time myFunction is called, it receives different Input and returns different MyResult. But I would like to keep the first MyResult to use for next called times of myFunction. How can I do that? Thanks very much for your answer in advance.

  • Where to place web server root?

    - by nefo_x
    Hello everybody, I've just made an upgrade and now partly thinking on web-server directory structure for local workstation for web-development on linux platform. Running multiple hosts and different projects required. Where is it better to put all the server's docroots? /var/www? /srv? /www? I plan to make it as separate partition - could it be good for backups? :) I'm looking forward to your thoughts on this.

  • Removing title from wp_list_cats()

    - by Alex
    I'm trying to remove/replace the title attribute on the category elements used by WordPress. I'm using WordPress 2.9.1, with the following code: <div id="categories"> <h3>Manufacturers</h3> <ul> <?php str_replace("title=\"View all posts filed under ","",wp_list_categories('use_desc_for_title=0&exclude=1,2,3,4,5&title_li=&hierarchical=1')); ?> </ul> </div> From what I had read this method used to work on older versions (I had never tried it though). I really don't want to hack at the interals of WordPress, or have to use a JavaScript hack, for something so straight forward. Any help is appreciated... Update below is what is created from the code above... Manufacturers Featured

  • Are your redirects HTTP compliant (absolute URI)?

    - by webbiedave
    In the Hypertext Transfer Protocol 1.1 spec, it states for the Location header: The field value consists of a single absolute URI. Location = "Location" ":" absoluteURI An example is: Location: http://www.w3.org/pub/WWW/People.html I have coded many an app that doesn't include the scheme and domain (i.e., /thankyou/) and every browser I've ever tested with redirects correctly. I'm wondering if it's imperative to go back and change all my redirect code or just ignore this part of the spec. Have many of you produced code that doesn't comply and will you go back and change it? Or will you just trust that clients will continue to resolve them well into the future? (going forward I will certainly adhere to this)

  • .NET: bool vs enum as a method parameter

    - by Julien Lebosquain
    Each time I'm writing a method that takes a boolean parameter representing an option, I find myself thinking: "should I replace this by an enum which would make reading the method calls much easier?". Consider the following with an object that takes a parameter telling whether the implementation should use its thread-safe version or not (I'm not asking here if this way of doing this is good design or not, only the use of the boolean): public void CreateSomeObject(bool makeThreadSafe); CreateSomeObject(true); When the call is next to the declaration the purpose of the parameter seems of course obvious. When it's in some third party library you barely know, it's harder to immediately see what the code does, compared to: public enum CreationOptions { None, MakeThreadSafe } public void CreateSomeObject(CreationOptions options); CreateSomeObject(CreationOptions.MakeThreadSafe); which describes the intent far better. Things get worse when there's two boolean parameters representing options. See what happened to ObjectContext.SaveChanges(bool) between Framework 3.5 and 4.0. It has been obsoleted because a second option has been introduced and the whole thing has been converted to an enum. While it seems obvious to use an enumeration when there's three elements or more, what's your opinion and experiences about using an enum instead a boolean in these specific cases?

  • Objective-C property getter

    - by Daniel
    What is technically wrong with the following: @property(nonatomic, assign) NSUInteger timestamp; @property(nonatomic, readonly, getter = timestamp) NSUInteger startTime; @property(nonatomic, assign) NSUInteger endTime; I am sure I can find a better way to organise this, but this is what I ended up with at one point in my project and I noticed that accessing the startTime property always returned 0, even when the timestamp property was set to a correct timestamp. It seems having set the getter of startTime to an existing property (timestamp), it is not forwarding the value of timestamp when I do: event.startTime => 0 event.timestamp => 1340920893 All these are timestamps by the way. Just a reminder, I know the above should have happened in my project but I don't understand why accessing startTime doesn't forward onto timestamp property. UPDATE In my implementation I am synthesising all of these properties: @synthesize timestamp, endTime, startTime; Please check an example object to use that demonstrates this at my gist on GitHub: https://gist.github.com/3013951

  • How do I create email addresses for all my users using my domain ([email protected])?

    - by rwain
    My client wants to create email addresses for all their dotnetnuke users using their domain. The point is to keep the user's email addresses 'private' while still allowing communication through a public email address that they can control. It's not necessary to have a full webmail interface (although that would be nice). I'm thinking it would be enough just to forward any mail on and just act as a gateway. So if an email was sent to [email protected], it would be forwarded on to the email address associated with the dotnetnuke account with username 'rwain'. Is this possible to do in a shared hosting environment? Or do I need to create some custom mail server that does a conversion of the email address and forwards it?

  • C++: Constructor/destructor unresolved when not inline?

    - by Anamon
    In a plugin-based C++ project, I have a TmpClass that is used to exchange data between the main application and the plugins. Therefore the respective TmpClass.h is included in the abstract plugin interface class that is included by the main application project, and implemented by each plugin. As the plugins work on STL vectors of TmpClass instances, there needs to be a default constructor and destructor for the TmpClass. I had declared these in TmpClass.h: class TmpClass { TmpClass(); ~TmpClass(); } and implemented them in TmpClass.cpp. TmpClass::~TmpClass() {} TmpClass::TmpClass() {} However, when compiling plugins this leads to the linker complaining about two unresolved externals - the default constructor and destructor of TmpClass as required by the std::vector<TmpClass> template instantiation - even though all other functions I declare in TmpClass.h and implement in TmpClass.cpp work. As soon as I remove the (empty) default constructor and destructor from the .cpp file and inline them into the class declaration in the .h file, the plugins compile and work. Why is it that the default constructor and destructor have to be inline for this code to compile? Why does it even maatter? (I'm using MSVC++8).

  • C# Spawn Multiple Threads for work then wait until all finished

    - by pharoc
    just want some advice on "best practice" regarding multi-threading tasks. as an example, we have a C# application that upon startup reads data from various "type" table in our database and stores the information in a collection which we pass around the application. this prevents us from hitting the database each time this information is required. at the moment the application is reading data from 10 tables synchronously. i would really like to have the application read from each table in a different thread all running in parallel. the application would wait for all the threads to complete before continuing with the startup of the application. i have looked into BackGroundWorker but just want some advice on accomplishing the above. Does the method sound logical in order to speed up the startup time of our application How can we best handle all the threads keeping in mind that each thread's work is independent of one another, we just need to wait for all the threads to complete before continuing. i look forward to some answers

  • Is it bad practice to select upstream servers based upon the HTTP method?

    - by PartlyCloudy
    I'm wondering if it is bad practice to have a reverse proxy that selects the upstream server depending on the HTTP method used? The background is that I have an abitrary web server that handles POST requests with some logic behind. The same resources also contain static content, that can be retrieved using GET. After some benchmarking I realized that nginx would handle the static content way faster than my abitrary web server doing this. I checked the option to forward incoming requests internally using nginx, which is feasible. But this would lead to the fact that different servers would serve a distinct resource, only depending on issuing a GET or POST, including different header fields.

  • Multiple conditions with will_paginate

    - by user363243
    I am using will_paginate for pagination but I can't seem to use more than one condition at a time. For example, if I want to have a sql query that ends in "Where office_id = 5", then it's pretty straight forward, I can do that. but what if I want to do "Where office_id = 5 AND primary_first = 'Mark'"? I can't do that. I have no idea how to enter multiple conditions. Can you help?? Below is an example of my code: def self.search(search, page, office_id) paginate :per_page => 5, :page => page, :conditions => ['office_id', "%#{office_id}"], # + ' and primary_first like ?', "%#{params[:search]}%"], #:conditions => ['primary_first', "%#{search}%"], :order => 'created_at' end Thank you for your help!

  • Good real-world uses of metaclasses (e.g. in Python)

    - by Carles Barrobés
    I'm learning about metaclasses in Python. I think it is a very powerful technique, and I'm looking for good uses for them. I'd like some feedback of good useful real-world examples of using metaclasses. I'm not looking for example code on how to write a metaclass (there are plenty examples of useless metaclasses out there), but real examples where you have applied the technique and it was really the appropriate solution. The rule is: no theoretical possibilities, but metaclasses at work in a real application. I'll start with the one example I know: Django models, for declarative programming, where the base class Model uses a metaclass to fill the model objects of useful ORM functionality from the attribute definitions. Looking forward to your contributions.

  • cuda 5.0 namespaces for contant memory variable usage

    - by Psypher
    In my program I want to use a structure containing constant variables and keep it on device all long as the program executes to completion. I have several header files containing the declaration of 'global' functions and their respective '.cu' files for their definitions. I kept this scheme because it helps me contain similar code in one place. e.g. all the 'device' functions required to complete 'KERNEL_1' are separated from those 'device' functions required to complete 'KERNEL_2' along with kernels definitions. I had no problems with this scheme during compilation and linking. Until I encountered constant variables. I want to use the same constant variable through all kernels and device functions but it doesn't seem to work. ########################################################################## CODE EXAMPLE ########################################################################### filename: 'common.h' -------------------------------------------------------------------------- typedef struct { double height; double weight; int age; } __CONSTANTS; __constant__ __CONSTANTS d_const; --------------------------------------------------------------------------- filename: main.cu --------------------------------------------------------------------------- #include "common.h" #include "gpukernels.h" int main(int argc, char **argv) { __CONSTANTS T; T.height = 1.79; T.weight = 73.2; T.age = 26; cudaMemcpyToSymbol(d_consts, &T, sizeof(__CONSTANTS)); test_kernel <<< 1, 16 >>>(); cudaDeviceSynchronize(); } --------------------------------------------------------------------------- filename: gpukernels.h --------------------------------------------------------------------------- __global__ void test_kernel(); --------------------------------------------------------------------------- filename: gpukernels.cu --------------------------------------------------------------------------- #include <stdio.h> #include "gpukernels.h" #include "common.h" __global__ void test_kernel() { printf("Id: %d, height: %f, weight: %f\n", threadIdx.x, d_const.height, d_const.weight); } When I execute this code, the kernel executes, displays the thread ids, but the constant values are displayed as zeros. How can I fix this?
