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

Returns:

Number of words produced onto stack by this instruction, or Constants.UNPREDICTABLE, if this can not be computed statically

getExceptions

public 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.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object
