  edu.rice.cs.cunit.instrumentors.AssignThreadIDStrategy

All Implemented Interfaces:

IInstrumentationStrategy

public class AssignThreadIDStrategy
extends java.lang.Object
implements IInstrumentationStrategy

Instrumentation strategy that adds code to java.lang.Thread to maintain a unique thread ID and an "old thread" flag. NOTE: This instrumentor has to be run AFTER the CompactSynchronizedDebugStrategy, otherwise the MONITORENTER and MONITOREXIT instructions will generate multiple sync points.
