harpoon.Instrumentation.AllocationStatistics
Class AllocationNumbering

java.lang.Object
  harpoon.Instrumentation.AllocationStatistics.AllocationNumbering

All Implemented Interfaces:

AllocationNumberingInterf, Serializable

public class AllocationNumbering
extends Object
implements AllocationNumberingInterf, Serializable

An AllocationNumbering object assigns unique numbers to each allocations site from a program and (possibly) to each call sites. Later, these numbers can be used in the instrumenting code (e.g. InstrumentAllocs).
