Constructor Detail

OrJoinInstance

public OrJoinInstance(java.lang.String[] transitions)

Constructs a new XOR-join instance.

Parameters:

transitions - IDs of afferent transitions.

Method Detail

shouldFire

public boolean shouldFire(java.lang.String transitionId)

Handles the activation of an afferent transition. An XOR-join fires as soon as one its afferent transitions has fired; subsequent activations of any of the transitions are ignored until the join is JoinInstance.reset().

Specified by:

shouldFire in class JoinInstance

Parameters:

transitionId - The ID of the transition that fired.

Returns:

true if the join fired.
