Method Details

accept

public void accept(Visitor v)

Overrides:
accept in interface Instruction

Parameters:
v - Visitor object

getExceptions

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

produceStack

public int produceStack(ConstantPoolGen cpg)
Specified by:
produceStack in interface StackProducer
Overrides:
produceStack in interface Instruction

Returns:
how many words are produced on stack
