public final class NodeUsageCollector
extends Object

Collects profile information for a bean (or reference/proxy bean) at a given AutoFetchNode.

The AutoFetchNode identifies the location of the bean in the object graph.

It has to use a weak reference so as to ensure that it does not stop the associated bean from being garbage collected.
