Class And

  com.ptc.windchill.upgrade.util.fsm.And

All Implemented Interfaces:

Condition

public final class And

extends Object

implements Condition

A logical AND'ing condition. If you have two condition instances, an instance of this class will return true if both of them are true.

Behavior is short circuiting. So if the first condition is false, the second will not be evaluated.

Example

   Condition cond1 = new FirstCondition();
   Condition cond2 = new SecondCondition();
   Condition ored_cond = new And(cond1, cond2)
