Class ProbeProviderClassFileTransformer

java.lang.Object

org.glassfish.flashlight.impl.client.ProbeProviderClassFileTransformer

All Implemented Interfaces:

ClassFileTransformer

public class ProbeProviderClassFileTransformer
extends Object
implements ClassFileTransformer

July 2012 Byron Nevins says: We no longer allow outsiders to create instances. Summary of the problem solved: All of the transformation/untransformation is done to the entire class (ProbeProvider) all at once. I.e. EVERY probe (method) is done all at once. BUT -- the callers are calling once for every Probe which was a huge waste of time.
