smart pointer for ZFObject

Macro Definition Documentation

zflineRelease

#define zflineRelease

(

obj

)

convenient method to release the object after code line end

usage:

ZFObject *allocObject(void) {
    return zfAlloc(ZFObject);
}
 
ZFArray *array = ...;
array->add( // step 2, array auto retain it, objectRetainCount 2
    zflineRelease(
            allocObject() // step 1, objectRetainCount 1
        )
    ); // step 3, zflineRelease auto release it, objectRetainCount 1
 
// equivalence:
// ZFObject *obj = allocObject();
// array->add(obj);
// zfRelease(obj);

usually, this method is used to save you some code, or designed for chained code

zfblockedRelease

#define zfblockedRelease

(

obj

)

release the object after nearest block

{ // code block
    ZFObject *obj = ...;
    zfblockedRelease(obj); // mark release, must be single line
    return; // safe to return, auto released after exiting code block
} // obj would be released after here
