It's faster because: - it uses a plain C interface so it doesn't incur Objective-c messaging overhead - it assumes you know what you're doing, so it doesn't spend time on safety checks (index out of bounds, required capacity etc.) - comparisons are done using pointer equality instead of isEqual There are 2 kind of functions: - ccArray functions that manipulates objective-c objects (retain and release are performed) - ccCArray functions that manipulates values like if they were standard C structures (no retain/release is performed) */ #ifndef CC_ARRAY_H #define CC_ARRAY_H #include "ccMacros.h" #include "cocoa/CCObject.h" #include #include #include NS_CC_BEGIN #define CC_INVALID_INDEX 0xffffffff // Easy integration #define CCARRAYDATA_FOREACH(__array__, __object__) \ __object__=__array__->arr[0]; for(unsigned int i=0, num=__array__->num; iarr[i]) \ typedef struct _ccArray { unsigned int num, max; CCObject** arr; } ccArray; /** Allocates and initializes a new array with specified capacity */ ccArray* ccArrayNew(unsigned int capacity); /** Frees array after removing all remaining objects.
