_Operation

public final class _IfV
extends _Goto

If the condition is true, set the program counter of the state machine.

            SMBuilder smb = new SMBuilder();
            boolean condition = true;
            smb._if(condition, "skip");
            condition = false;
            smb._set(new ObjectFunc() {
                public Object get(StateMachine sm) {
                    System.out.println("does not print");
                    return null;
                }
            });
            smb._label("skip");
            smb._set(new ObjectFunc() {
                public Object get(StateMachine stateMachine) {
                    System.out.println("Hello world!");
                    return null;
                }
            });
            smb.call(rp);

            Output:
            Hello world!
