All Implemented Interfaces:

Serializable

public class PGCNiftyAllocationStrategyWithStats
extends PGCNiftyAllocationStrategy

PGCNiftyAllocationStrategyWithStats adds a callback to properly update statistics after stack allocation. This is pretty pointless, because you could just fake the stack allocation to get the statistics, but... Martin apparently wants it this way.

This code originally written by Brian; Scott rearranged it.
