# c-foundation

## 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.

```C

// 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);

```
