  • Choosing a design pattern for a class that might change it's internal attributes

    - by the_drow
    I have a class that holds arbitrary state and it's defined like this: class AbstractFoo { }; template <class StatePolicy> class Foo : public StatePolicy, public AbstractFoo { }; The state policy contains only protected attributes that represent the state. The state might be the same for multiple behaviors and they can be replaced at runtime. All Foo objects have the same interface to abstract the state itself and to enable storing Foo objects in containers. I would like to find the least verbose and the most maintainable way to express this.

  • Should I use a metaclass, class decorator, or override the __new__ method?

    - by 007brendan
    Here is my problem. I want the following class to have a bunch of property attributes. I could either write them all out like foo and bar, or based on some other examples I've seen, it looks like I could use a class decorator, a metaclass, or override the __new__ method to set the properties automagically. I'm just not sure what the "right" way to do it would be. class Test(object): def calculate_attr(self, attr): # do calculaty stuff return attr @property def foo(self): return self.calculate_attr('foo') @property def bar(self): return self.calculate_attr('bar')

  • How to append html to first occurance of string after selected element

    - by uku
    Hello, I have html like so: <div class=foo> (<a href=forum.example.com>forum</a>) <p> Some html here.... </div> And I want to insert another link after the first one, like so: <div class=foo> (<a href=forum.example.com>forum</a>) <a href=blog.example.com>blog</a> <p> Some html here.... </div> ...but because it is enclosed in () I cannot use: $('div.foo a:first').append(' <a href=blog.example.com>blog</a>'); ...which would place it before the ). So how can I extend my jQuery selection to select the literal ) or do I need to use another solution?

  • In C++, what is the "order of precedence" for shadowed variable names?

    - by Emile Cormier
    In C++, what is the "order of precedence" for shadowed variable names? I can't seem to find a concise answer online. For example: #include <iostream> int shadowed = 1; struct Foo { Foo() : shadowed(2) {} void bar(int shadowed = 3) { std::cout << shadowed << std::endl; // What does this output? } int shadowed; }; int main() { Foo().bar(); } I can't think of any other scopes where a variable might conflict. Please let me know if I missed one.

  • C++ cast syntax styles

    - by palm3D
    A question related to Regular cast vs. static_cast vs. dynamic_cast: What cast syntax style do you prefer in C++? C-style cast syntax: (int)foo C++-style cast syntax: static_cast<int>(foo) constructor syntax: int(foo) They may not translate to exactly the same instructions (do they?) but their effect should be the same (right?). If you're just casting between the built-in numeric types, I find C++-style cast syntax too verbose. As a former Java coder I tend to use C-style cast syntax instead, but my local C++ guru insists on using constructor syntax. What do you think?

  • Using Jquery, call function on selection just once

    - by maxp
    Say i have a selection of textboxes like this; var arrayoftextboxes = $('.textbox1, .textbox2, .textbox3'); Is there a way I can call a function on each one in a simpler way than this? It only needs to be called once. arrayoftextboxes.each(function(i){foo(arrayoftextboxes[i]);}); I tried arrayoftextboxes.load(function(){foo(this)}); and arrayoftextboxes.bind(function(){foo(this)}); but the functions dont seem to be called.

  • Is it bad practice to change state inside of an if statement?

    - by Benjamin
    I wrote some code that looks similar to the following: String SKIP_FIRST = "foo"; String SKIP_SECOND = "foo/bar"; int skipFooBarIndex(String[] list){ int index; if (list.length >= (index = 1) && list[0].equals(SKIP_FIRST) || list.length >= (index = 2) && (list[0] + "/" + list[1]).equals(SKIP_SECOND)){ return index; } return 0; } String[] myArray = "foo/bar/apples/peaches/cherries".split("/"); print(skipFooBarIndex(myArray); This changes state inside of the if statement by assigning index. However, my coworkers disliked this very much. Is this a harmful practice? Is there any reason to do it?

  • How should I declare default values for instance variables in Python?

    - by int3
    Should I give my class members default values like this: class Foo: num = 1 or like this? class Foo: def __init__(self): self.num = 1 In this question I discovered that in both cases, bar = Foo() bar.num += 1 is a well-defined operation. I understand that the first method will give me a class variable while the second one will not. However, if I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other? One thing I've noticed is that in the Django tutorial, they use the second method to declare Models. Personally I think the second method is more elegant, but I'd like to know what the 'standard' way is.

  • From comma separated list to individual item result set. *mysql

    - by Raziel
    I'm doing some data migration from a horribly designed database to a less horribly designed database. There is a many to many relationship that has a primary key in one table that corresponds to a comma separated list in another. FK_ID | data ------------- 1,2 | foo 3 | bar 1,3,2 | blarg Is there a way to output the FK_ID field with each comma separated element as a single line in the result set? result set FK_ID | data ------------- 1 | foo 2 | foo 3 | bar 1 | blarg 2 | blarg 3 | blarg I'm thinking this would require some sort of recursive query which I don't think mysql has. Thanks in advance.

  • In Node.JS, how do I return an entire object from a separate .js file?

    - by Matthew Patrick Cashatt
    Thanks for looking. I am new to Node.js and trying to figure out how to request an object from a separate file (rather than just requesting a function) but everything I try--exports,module-exports,etc--is failing. So, for example, if I have foo.js: var methods = { Foobar:{ getFoo: function(){return "foo!!";}, getBar: function(){return "bar!!";} } }; And now I want to call a function within an object of foo.js from index.js: var m = require('./Methods'); function fooMain(){ return m.Foobar.getFoo(); }; How do I do this? I have tried all sorts of combinations of exports and module-exports but they seem to only work if I call a discrete function that is not part of an object. Thanks!

  • How to specify schema location in an xsd file?

    - by Manoj
    I have an xsd file Foo.xsd. I tried following ways to refer it in a WSDL file but it doesnt work. 1) placed the xsd file in local file system and imported it as <xsd:import namespace="http://ws.test.com/" schemaLocation="file:///D:/wsdl/Foo.xsd"></xsd:import> 2) Placed the xsd file in web root folder and imported as <xsd:import namespace="http://ws.test.com/" schemaLocation="http://localhost:8080/Xfire/Foo.xsd"></xsd:import> When I run the client I get null for the fields of response object. But this works when I embed the type definition inside the WSDL itself. How do we specify the path to external xsds? I am using xFire 1.2.6 for generating webservices. Client is generated using xFire WSGen ant task.

  • Constructor Type Coercion in C++

    - by Robert Mason
    Take the following class: class mytype { double num; public: mytype(int a) { num = sqrt(a); } void print() { cout << num; } } Say there is a method which takes a mytype: void foo(mytype a) { a.print(); } Is it legal c++ (or is there a way to implement this) to call foo(4), which would (in theory) output 2? From what I can glean you can overload type casts from a user defined class, but not to. Can constructor do this in a standards-compliant manner (assuming, of course, the constructor is not explicit). Hopefully there is a way to in the end have this legal: int a; cin >> a; foo(a); Note: this is quite obviously not the actual issue, but just an example for posting purposes. I can't just overload the function because of inheritance and other program-specific issues.

  • Bind jQuery UI autocomplete using .live()

    - by seth.vargo
    I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

  • How to commit a non-subversioned file into a repository ?

    - by devdude
    The environment: SVN, Netbeans, Hudson SVN Project A: Builds a library file (foo.jar). The build file is under /dist, which is ignored for svn, the sourcecode is under svn control. SVN Project B: holds all library files. (other SVN projects get all their libraries from here via external svn) Question: I want to commit foo.jar from A into B. How to do that ? foo.jar cannot be added or committed because it is not under SVN control. Thanks for any hints ! (The question is independent from the IDE and CI Server)

  • C# to Java Conversion: What is a [DefaultProperty("value")]?

    - by Shiftbit
    I do not understand how the DefaultProperty Metadata tag work or what it signifies. I've read the MSDN and went through the sample but I find it confusing. DefaultPropertyAttribute Class I've read a few blogs and they seem to refer to the indexers. I'm not sure why you would want metadata for your properties? I am coming from a Java background, perhaps a Java analogy would help. [DefaultProperty("Value")] public abstract class FOO<T> : ANY, IBAR<T> { public FOO() { } public FOO(T value) { this.Value = value; } public virtual T Value { get; set; } }

  • Code crashing compiler: main() returning a struct instead of an int

    - by AndrejaKo
    Hi! I'm experimenting with a piece of C code. Can anyone tell me why is VC 9.0 with SP1 crashing for me? Oh, and the code is meant to be an example used in a discussion why something like void main (void) is evil. struct foo { int i; double d; } main (double argc, struct foo argv) { struct foo a; a.d=0; a.i=0; return a.i; } If I put return a; compiler doesn't crash.

  • PHP Type Hinting: array supported, object NOT?

    - by Marius Burz
    Am I missing something or there really is no support for generic object type hinting in PHP 5.x? I find it really strange that hinting arrays is supported while hinting objects is not, at least not out of the box. I'd like to have something like this: function foo(object $o) Just as we have: function foo(array $o) Example of possible use: methods of an objects collection class. Workaround: using an interface "Object" implemented by all classes or extending all classes from a generic class "Object" and writing something like this: function foo(Object $o) Well, that just ain't cute. Edit: somebody suggested in a deleted post using stdClass. It doesn't work: Catchable fatal error: Argument 1 passed to c::add() must be an instance of stdClass, instance of b given

  • Excel XML Newline in Cell

    - by spasarto
    I am using LINQ to XML to create an Excel XML file. I want to include newlines within the cells. Excel uses the &#10; literal to represent a new line. If I try to add this using an XText: XText newlineElement = new XText( "Foo&#10;Bar" ); I get: Foo&amp;#10;Bar Which shows up in Excel as: Foo&#10;Bar Is there a way to write &#10 to the XML file without doing a String.Replace( "&amp;#10;", "&#10;" ) over the resulting file text?

  • Test param value using EasyMock

    - by fmpdmb
    I'm attempting to write some unit tests using EasyMock and TestNG and have run into a question. Given the following: void execute(Foo f) { Bar b = new Bar() b.setId(123); f.setBar(b); } I'm trying to test that the Id of the Bar gets set accordingly in the following fashion: @Test void test_execute() { Foo f = EasyMock.createMock(Foo.class); execute(f); Bar b = ?; // not sure what to do here f.setBar(b); f.expectLastCall(); } In my test, I can't just call f.getBar() and inspect it's Id because f is a mock object. Any thoughts? Is this where I'd want to look at the EasyMock v2.5 additions andDelegateTo() and andStubDelegateTo()?

  • Casting a container of shared_ptr

    - by Jamie Cook
    Hi all, I have a method void foo(list<shared_ptr<Base>>& myList); Which I'm trying to call with a two different types of lists, one of DerivedClass1 and one of DerivedClass2 list<shared_ptr<DerivedClass1>> myList1; foo(myList1); list<shared_ptr<DerivedClass2>> myList2; foo(myList2); However this obviously generates a compiler error error: a reference of type "std::list<boost::shared_ptr<Base>, std::allocator<boost::shared_ptr<Base>>> &" (not const-qualified) cannot be initialized with a value of type "std::list<boost::shared_ptr<DerivedClass1>, std::allocator<boost::shared_ptr<DerivedClass1>>>" Is there any easy way to cast a container of shared_ptr? Of alternate containers that can accomplish this?

  • Constructor with non-instance variable assistant?

    - by Robert Fischer
    I have a number of classes that look like this: class Foo(val:BasicData) extends Bar(val) { val helper = new Helper(val) val derived1 = helper.getDerived1Value() val derived2 = helper.getDerived2Value() } ...except that I don't want to hold onto an instance of "helper" beyond the end of the constructor. In Java, I'd do something like this: public class Foo { final Derived derived1, derived2; public Foo(BasicData val) { Helper helper = new Helper(val); derived1 = helper.getDerived1Value(); derived2 = helper.getDerived2Value(); } } So how do I do something like that in Scala? I'm aware of creating a helper object of the same name of the class with an apply method: I was hoping for something slightly more succinct.

  • Stop PHP from creating arrays in $_POST superglobal

    - by cdmckay
    PHP will automatically convert <input type="text" name="foo[0]" value="x" /> <input type="text" name="foo[1]" value="y" /> into $_POST['foo'] = array( 0 => 'x', 1 => 'y' ); Which is what you want most of the time. However, in this case I would like this not to happen. Is there anyway to tell PHP to not do this? I realize I could parse php://input myself, but I'd rather not do that if I can avoid it. I also don't have the option of renaming the input names.

  • Cached Jquery selector behavior that I do not understand

    - by gaoshan88
    Given the following code why am I getting different values for a and b? I would have thought they would return the same thing: (function() { var a = $('#foo'); var Test = function(){ console.log(a); //outputs 'jQuery()' var b = $('#foo'); console.log(b); //outputs 'jQuery(select#foo)' which is what I want }; })(); This question stems from me trying to stick frequently used selectors into vars. Originally I was doing it in each method (like I did with var b in the above example) but then I found I needed to use the selectors in multiple methods so I moved the assignment out to be available (or so I thought) to all of the methods in that anonymous function. As you can see, it does not work. Why is this?

  • Java, how to trace functions called

    - by user435657
    Hi all, I want to trace the beginning [& ending] of functions called in Java, like the following code: public void foo() { System.out.println("begin of foo()"); ... System.out.println("e-n-d of foo()"); } But maintaining of the dump code System.out.println is something tedious and error-prone, for there may be tens of thounds of function in an class. Any good idea can ease this work? I don't want dump statements all over the file. Implementation of both or one of the beginning & ending traces is perferd. But, if impossible, recordings of that the function has been called is also helpful. I mean not care the exact beginnig and ending, just tell that the function has been called.
