Method Detail

negate

public IfInstruction negate()
Specified by:
negate in class IfInstruction
Returns:
negation of instruction

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:
