About

This project provides a basic implementation of the C Object/Class system (think CGImageRef) found in Apple's Core Foundation and Core Graphics frameworks.

The object system used in these frameworks offers several key features that can be a big help in building a great C API.

• Memory management with reference counting.
• Full object encapsulation. (Clean headers!)
• Mutable and immutable objects.
• Polymorphic methods for core operations (retain, release, autorelease, copy, etc).

Example

A simplified string and array class are included to demonstrate the object system.

// Create a mutable object
ISMutableStringRef mutable = ISStringCreateMutable("a mutable string", ISASCIIStringEncoding);
ISStringRef string = ISStringCreate("a static string", ISASCIIStringEncoding);

// functions work on both mutable and nonmutable objects
int stringLength = ISStringLength(string);

int length = ISStringLength(mutable);

// certain functions only work on mutable objects
ISStringReplaceCharacters(mutable, 's', 'q');

// release
ISRelease(string);
