public class TransitionCondition
extends Transition

Statechart transition with trigger of type condition. The transition is executed when the condition becomes true. If the active object has continuously changing variables, the numeric engine constantly monitors the condition. In purely discrete models the condition is tested when something changes in the active obejct, i.e. when onChange() is called. If the guard appears to be false when the transition is about to execute, it is not taken and becomes inactive until the next next condition evaluation.
Memory: sizeof(Transition) = 22 bytes
