API ObjectPoolMixin Acquire

Furnishes a widget, or returns it to the. widget = pool:Acquire success = pool:Release(widget) pool:ReleaseAll

• widget : - Furnished by Acquire or returned by Release.
• success : - Returned by Release as true if returning the widget to the pool, or false otherwise (the widget is not even part of the pool, or was previously returned).

• Acquire draws a widget from the pool, preferring to reuse a previously-released one but using the pool's creationFunc if necessary.
• Widgets are reused in reverse order to how they were released (LIFO).
• All three functions apply the pool's resetterFunc (unless it is nil) to affected widgets during each operation.
• ReleaseAll returns all widgets to the pool.
