When call AS3_Release

Question

If I create an object in C++ code and return it in ActionScript code should I call AS3_Release before returning it? For example, I have the function in the *.gg file:

public function makeThumbnail(...): Object
{
     AS3_Val objDestByteArray = AS3_New(ByteArray_class, no_params);
     int intDestWidth;
     int intDestHeight;

     // ...  make some calculations and set results as object properties

     AS3_Val result = AS3_Object("width:IntType, height:IntType, data:AS3ValType", intDestWidth, intDestHeight, objDestByteArray);

     // Do I need to call this?
     //AS3_Release(objDestByteArray);
     //AS3_Release(result);

     return result;
}

Should I call AS3_Release for objDestByteArray and result variables?

Answer 1

All unique AS3_Val variables need to be released eventually. For AS3_Val return variables, the function doesn't release the value itself but instead assumes that its caller will arrange for the value's eventual release.

So in your example, release objDestByteArray but don't release result yet. Whoever is calling makeThumbnail is responsible for releasing its return value.
