Examples of alt.jiapi.instrumentor.ChainInstrumentor

alt.jiapi.instrumentor.ChainInstrumentor
In instrumentation process, the InstrumentorChain has references to one or more Instrumentors. These instrumentors are activated (using method instrument) in the order which they are in a list. @author Mika Riekkinen @author Joni Suominen @version $Revision: 1.1 $ $Date: 2004/03/15 14:45:06 $
