Value:

Definition rave_object.c:172

Creates a clone of a object.

Not to be confused with COPY. I.e. basically the same as doing a NEW followed by a copy of all essential members. Be aware that not all objects supports this function and in that case, NULL will be returned. If it is interesting to ensure that everything is successful, you can always do this:

* if (RAVE_OBJECT_ISCLONEABLE(src)) {
*   clone = RAVE_OBJECT_CLONE(src);
*   if (clone == NULL) {
*     // memory allocation error or something
*   }

(obj) = NULL;

RaveCoreObject_release

void RaveCoreObject_release(RaveCoreObject *obj, const char *filename, int lineno)

Definition rave_object.c:145

Releases the provided object once (i.e.

decrements the reference counter and sets the invalue to NULL. Ie. Do not do something funny like: RAVE_OBJECT_RELEASE(x[index++]) since that will mess up the memory, instead write RAVE_OBJECT_RELEASE(x[index]); index++

Typedef Documentation

◆ RaveCoreObject

typedef struct _raveobject RaveCoreObject

The basic raveobject that contains the header information for all rave objects.

◆ RaveCoreObjectType

typedef struct _raveobjecttype RaveCoreObjectType

The rave object type definition.

If you are implementing support for the copy constructor, you must ensure that all members of the object are clones as well so that there are no references to other objects.

[in]	filename	- the filename that this operation was performed in
[in]	lineno	- the linenumber that this operation was performed in

◆ RaveCoreObject_setTrackObjects()
