Methods

virtual void CCL_API connectPersistentOwner (
    IPersistentOwner* owner,
    ObjectID oid
)

Connect object to an owner.

virtual ObjectID CCL_API getObjectID ()

Get object id passed in connectPersistentOwner.

virtual tresult CCL_API queryInterface (UIDRef iid, void** ptr)

Obtain pointer to another interface supported by this object.

In case of success, the caller holds a reference to this interface, which must be released afterwards.

Parameters:

iid	ID of requested interface (e.g. “ccl_iid<ISomething> ()”)
ptr	receives pointer to requested interface

Returns:

kResultOk for success, kResultNoInterface if unsupported.

virtual unsigned int CCL_API retain ()

Increments the object’s reference count.

virtual unsigned int CCL_API release ()

Decrement the object’s reference count.

If the reference count reaches zero, the object is freed in memory.
