Class Rewriter.ModifyTypeTraversal

java.lang.Object
  jist.runtime.ClassTraversal.Empty
      jist.swans.Rewriter.ModifyTypeTraversal

All Implemented Interfaces:

ClassTraversal.Visitor

Enclosing class:

Rewriter

public static class Rewriter.ModifyTypeTraversal
extends ClassTraversal.Empty

Class traversal that substitutes types in all the common places.

Since:

SWANS1.0

Constructor Summary

Rewriter.ModifyTypeTraversal(jist.swans.Rewriter.ModifyTypeInfo[] modifications)
Create a type-modifying traversal object.

Method Summary

org.apache.bcel.generic.ClassGen	doClass(org.apache.bcel.generic.ClassGen cg) Upcall to process class before field and method processing.
org.apache.bcel.generic.FieldGen	doField(org.apache.bcel.generic.ClassGen cg, org.apache.bcel.generic.FieldGen fg) Upcall to process field.
void	doInstruction(org.apache.bcel.generic.ClassGen cg, org.apache.bcel.generic.MethodGen mg, org.apache.bcel.generic.InstructionHandle ih, org.apache.bcel.generic.Instruction inst) Upcall to process instruction. Note that instructions can be inserted and deleted directly using the BCEL API, and therefore this method returns void.
org.apache.bcel.generic.MethodGen	doMethod(org.apache.bcel.generic.ClassGen cg, org.apache.bcel.generic.MethodGen mg) Upcall to process method before instruction processing.

Method Detail

doClass

public org.apache.bcel.generic.ClassGen doClass(org.apache.bcel.generic.ClassGen cg)

Upcall to process class before field and method processing.

Specified by:

doClass in interface ClassTraversal.Visitor

Overrides:

doClass in class ClassTraversal.Empty

Parameters:

cg - BCEL class generator object to process

Returns:

processed BCEL class generator object

doField

public org.apache.bcel.generic.FieldGen doField(org.apache.bcel.generic.ClassGen cg,
                                                org.apache.bcel.generic.FieldGen fg)

Upcall to process field.

Specified by:

doField in interface ClassTraversal.Visitor

Overrides:

doField in class ClassTraversal.Empty

Parameters:

cg - BCEL class generator object

fg - BCEL field generator object to process

Returns:

processed BCEL field generator object

doMethod

public org.apache.bcel.generic.MethodGen doMethod(org.apache.bcel.generic.ClassGen cg,
                                                  org.apache.bcel.generic.MethodGen mg)

Upcall to process method before instruction processing.

Specified by:

doMethod in interface ClassTraversal.Visitor

Overrides:

doMethod in class ClassTraversal.Empty

Parameters:

cg - BCEL class generator object

mg - BCEL method generator object to process

Returns:

processed BCEL method generator object

doInstruction

public void doInstruction(org.apache.bcel.generic.ClassGen cg,
                          org.apache.bcel.generic.MethodGen mg,
                          org.apache.bcel.generic.InstructionHandle ih,
                          org.apache.bcel.generic.Instruction inst)

Upcall to process instruction. Note that instructions can be inserted and deleted directly using the BCEL API, and therefore this method returns void.

Specified by:

doInstruction in interface ClassTraversal.Visitor

Overrides:

doInstruction in class ClassTraversal.Empty

Parameters:

cg - BCEL class generator object

mg - BCEL method generator object

ih - BCEL instruction handle object to process

inst - BCEL instruction object to process
