weak_ref

Description:

public void weak_ref (MiniObjectNotify notify)

Adds a weak reference callback to a mini object.

Weak references are used for notification when a mini object is finalized. They are called "weak references" because they allow you to safely hold a pointer to the mini object without calling @ref (gst_mini_object_ref() adds a strong reference, that is, forces the object to stay alive).

Parameters:

this	MiniObject to reference weakly
notify	callback to invoke before the mini object is freed
data	extra data to pass to notify
