Class: Reference

Defined in: src/util/Reference.ts:12

instance reference statistics module apply any instance , used full destroy

Outer map is a WeakMap so a resource (ref) doesn't stay alive merely because Reference knows about it — its _boundCtx back-ref would otherwise pin the owning Context3D forever across engine reinits. Inner map retains parents strongly (that's the whole point of the tracker), but it evaporates with the ref once nothing else holds it.
