Method Detail

doClass

org.apache.bcel.generic.ClassGen doClass(org.apache.bcel.generic.ClassGen cg)
                                         throws java.lang.ClassNotFoundException

Upcall to process class before field and method processing.

Parameters:

cg - BCEL class generator object to process

Returns:

processed BCEL class generator object

Throws:

java.lang.ClassNotFoundException

doClassPost

org.apache.bcel.generic.ClassGen doClassPost(org.apache.bcel.generic.ClassGen cg)
                                             throws java.lang.ClassNotFoundException

Upcall to process class after field and method processing.

Parameters:

doField

org.apache.bcel.generic.FieldGen doField(org.apache.bcel.generic.ClassGen cg,
                                         org.apache.bcel.generic.FieldGen fg)
                                         throws java.lang.ClassNotFoundException

Upcall to process field.

Parameters:

cg - BCEL class generator object

fg - BCEL field generator object to process

Returns:

processed BCEL field generator object

Throws:

java.lang.ClassNotFoundException

doMethod

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

Upcall to process method before instruction processing.

Parameters:

cg - BCEL class generator object

mg - BCEL method generator object to process

Returns:

processed BCEL method generator object

Throws:

java.lang.ClassNotFoundException

doMethodPost

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.

Parameters:

cg - BCEL field generator object

mg - BCEL method generator object to process

Returns:

processed BCEL method generator object

Throws:

java.lang.ClassNotFoundException

doInstruction

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 i)
                   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.

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
