doMethodPost

public org.apache.bcel.generic.MethodGen doMethodPost(org.apache.bcel.generic.ClassGen cg,
                                                      org.apache.bcel.generic.MethodGen mg)
                                               throws java.lang.ClassNotFoundException

Upcall to process method after instruction processing.

Specified by:

doMethodPost in interface ClassTraversal.Visitor

Parameters:

cg - BCEL field generator object

mg - BCEL method generator object to process

Returns:

processed BCEL method generator object

Throws:

doInstruction

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

                   throws java.lang.ClassNotFoundException

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

Parameters:

cg - BCEL class generator object

mg - BCEL method generator object

ih - BCEL instruction handle object to process

i - BCEL instruction object to process

Throws:

java.lang.ClassNotFoundException
