buffer

protected static ByteBufferedFile buffer

A buffer used to buffer events sent from event-generating JVM to event-handling JVM. It is irrelevant if events are generated/handled by the same JVM.

public TraceEventHandler()

Method Detail

init

public static void init(java.lang.String args)

This method is called during handing of JVMTI event "VMInit". arguments: trace_file, trace_block_size if trace_file is absent then buffer is not created (i.e. it is assumed that dynamic analysis is intra-JVM).

done

public static void done()
