Class MethodTransformer

java.lang.Object
  org.jxcl.cl.MethodTransformer

public class MethodTransformer
extends java.lang.Object

Optionally preprocesses a method, optionally transforms its control flow graph, optionally postprocesses it. The list of preprocessors is applied in forward order before graph transformation. The corresponding list of postprocessors is applied in reverse order after graph transformation.

Field Summary

private java.util.List gxf
          Graph processors.

private java.util.Hashtable methodHash
          For passing application-specific data.

private java.util.List mxf
          Ordered list of method pre- and post-processors.

private GraphTransformer xformer
          Main graph processor.

Constructor Summary

MethodTransformer(java.util.List mxf, java.util.List gxf)
          Sets up method transformer, saving MethodXformer vector here and passing GraphXformer vector to that transformer.

Method Summary

(package private) void dumpExceptionHandlers(org.apache.bcel.generic.MethodGen method, java.lang.String where, int len)


(package private) void dumpIList(org.apache.bcel.generic.MethodGen method, java.lang.String where)


java.util.Hashtable getMethodHash()
          Get a reference to the hash used to share data between this and other transformers.

org.apache.bcel.generic.MethodGen xform(org.apache.bcel.generic.ClassGen clazz, org.apache.bcel.classfile.Method orig)
          Transform a specific method, first applying preprocessors, then transforming the graph, then applying method postprocessors.

private void zapMethodXformer(MethodXformer mxf, java.lang.Exception e)
          Zero out a badly-behaved method Xformer.
