wrapper

Here's what I did, trying to create a wrapper for a dict-like database, among other functions: class database(object): def __init__(self, name): self.name = name self.db = anydbm.open(name, 'c') def __getitem__(self, key): key = str(key) try: self.db = anydbm.open(self.name, 'w') except Exception,e: raise e else: return cPickle.loads(self.db[key]) finally: self.db.close() def __setitem__(self, key, value): key = str(key) value = cPickle.dumps(value) try: self.db = anydbm.open(self.name, 'w') except Exception,e: print e else: self.db[key] = value finally: self.db.close() When I try to define a

What is the reason why Wrapper classes (like Integer, Double, etc.) don't have a setter for their inner primitive value ? I am asking this because that kind of functionality would have simplified calculus, and have made the Java language a little more flexible . Let me give you some examples. 1) Let's take the following example: Integer x = new Integer(5); x++; The previous code behind the scenes is performing autoboxing . Something like: int x_tmp = x.intValue(); x_tmp++; x = new Integer(x_tmp); // Yes that's a new memory allocation Because of this problem doing calculus on Wrapper is slower

Has anyone encountered a nice wrapper for GhostScript in C#. My specific use is to take postscript and turn it into a pdf AJ. Open-source PDFSharp has a namespace for using GhostScript. Even if you can't directly use it, you can probably graft whatever you need out of the source. Mattygabe Matthew Ephraim has created a pretty simple C# wrapper called GhostScriptSharp that uses P/Invoke to access the unmanaged Ghostscript DLL in your C# application: http://mattephraim.com/blog/2009/01/06/a-simple-c-wrapper-for-ghostscript/ For completeness, there's also Gouda Ghostscript wrapper . You can also

Consider the following class: class MyClass1 { public: double x() const {return _x;} // getter double y() const {return _y;} // getter double z() const {return _x*_y;} // getter void x(const double var) {_x = var;} // setter void y(const double var) {_y = var;} // setter void z(const double var) {_x = var; _y = 1;} // setter protected: double _x; double _y; }; As the actual contents of MyClass1 is an implementation detail, the getters and setters provide a unified way to get and set the class contents even if they are interdependant (here _z does not exists internally but for the user, z is a

I have an html structure that looks like this: <h5>Title</h5> <p> Content </p> <ul> <li>Item</li> <li>Item</li> </ul> <p> Content </p> <h5>Title</h5> <p> Content </p> <ul> <li>Item</li> <li>Item</li> </ul> <p> Content </p> In summary it's just some headers with content below them, I just need everything below the header tags in a div like this: <h5>Title</h5> <div> <p> Content </p> <ul> <li>Item</li> <li>Item</li> </ul> <p> Content </p> </div> I've tried using the .wrap function of jQuery but no luck since there can be multiple types elements below the header tags, I found this question:

I need the way to intercept all ajax requests maded from page. So i need some wrapper to add my data to all users requests. Andrey Nikishaev Huh... i made this work))) with help of this topic Extending an ActiveXObject in javascript i made script that intercept all ajax requests no matter what framework or browser do user use. You can look at it here: Script I dont think you can get this out of the box . What you need here is a little restructuring of your client side code [ You should have already done that , but it is never too late :) ] . Make a function that has the responsibility of

I have a Cocoa project (a Mac OS X app), all Objective-C. I pulled in one C++ class (which I know works) from another project, and make an Objective-C wrapper for it. The ObjC wrapper class is using a .mm extension. However, the C++ header file contains #include s to standard C++ header files ( <vector> , for example), and I get errors on those. A minimal example would look like the following. CppClass is the C++ class, and CppWrapper is the ObjC class which wraps it. // CppClass.h #ifndef _CPP_CLASS_H_ #define _CPP_CLASS_H_ #include <vector> class CppClass { public: CppClass() {} ~CppClass()

Calling into C from Swift is pretty simple, however I'm looking into making a bi-directional wrapper in C, so my C has to call Swift functions. Right now, I can do this by declaring function pointers in C, and having my C functions call them after the Swift side has set them up to call code in Swift. My C header file: typedef void (*callback_t)(void); void callBackIntoSwift( callback_t cb ); My C implementation file: #include "stuff.h" #include <stdio.h> void callBackIntoSwift( callback_t cb ) { printf( "Will call back into Swift\n" ); cb(); printf( "Did call back into Swift\n" ); } After
