Enum TransitionConflictPolicy

java.lang.Object

java.lang.Enum<TransitionConflictPolicy>

org.springframework.statemachine.transition.TransitionConflictPolicy

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TransitionConflictPolicy>

public enum TransitionConflictPolicy
extends java.lang.Enum<TransitionConflictPolicy>

Enumerations for possible transition conflict policies. In case multiple transitions become possible, thus machine having a need to choose one, these policies determine if transition is picked from originating child or parent states.
