Method Detail

produceStack

public int produceStack(ConstantPoolGen cpg)
Description copied from class: Instruction
This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.
Specified by:
produceStack in interface StackProducer
Overrides:
produceStack in class Instruction
Following copied from interface: org.apache.bcel.generic.StackProducer
Returns:
how many words are produced on stack

getExceptions

public java.lang.Class[] getExceptions()
Specified by:
getExceptions in interface ExceptionThrower

accept

public void accept(Visitor v)
Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
Overrides:
accept in class Instruction
Parameters:
v - Visitor object
