All Implemented Interfaces:

Cloneable

public class InstrumentStreamableTask
extends Task

Instruments compiled Streamable classes with public methods that can be used to stream protected and private members when running in a sandboxed JVM.

Field Summary

protected ArrayList<FileSet>	_filesets A list of filesets that contain Streamable class files.
protected File	_outdir The directory to which we write our instrumented class files.
protected ArrayList<Path>	_paths A list of paths that make up our classpath.
protected javassist.ClassPool	_pool Used to instrument class files.
protected javassist.CtClass	_streamable Used to determine which classes implement Streamable.
protected static String	BSNAME
