/** @def CCARRAY_FOREACH
A convience macro to iterate over a CCArray using. It is faster than the "fast enumeration" interface.
@since v0.99.4
*/

/*
In cocos2d-iphone 1.0.0, This macro have been update to like this:

#define CCARRAY_FOREACH(__array__, __object__)												\
if (__array__ && __array__->data->num > 0)													\
for(id *__arr__ = __array__->data->arr, *end = __array__->data->arr + __array__->data->num-1;	\
__arr__ <= end && ((__object__ = *__arr__) != nil || true);										\
__arr__++)

I found that it's not work in C++. So it keep what it's look like in version 1.0.0-rc3. ---By Bin

#define CCARRAY_FOREACH(__array__, __object__)												\
    if (__array__ && __array__->data->num > 0)													\
    for(CCObject** arr = __array__->data->arr, **end = __array__->data->arr + __array__->data->num-1;	\
    arr <= end && ((__object__ = *arr) != NULL/* || true*/);										\
