Field Detail
_states
final protected boolean[] _states(Code)



_transitions
final protected String[] _transitions(Code)




Constructor Detail
JoinInstance
protected JoinInstance(String[] transitions)(Code)




Method Detail
didFire
final protected synchronized boolean didFire(int index)(Code)
Sets the fired state for the specified transition. A change of state marks the join as modified.
Parameters:
  index - Index to set. Whether the transition fired.



equals
final public synchronized boolean equals(Object obj)(Code)



fire
final protected synchronized void fire()(Code)
Informs the join that it has fired. If it has not already fired it is marked as both fired and modified, which states persist until it is reset and persisted respectively. Firing a join also increments its JoinInstance.getFiredCount() fired count .



getFiredCount
final public synchronized int getFiredCount()(Code)
Returns the number of times the join has fired since the workflow started. Fire count;



hasFired
final public synchronized boolean hasFired()(Code)
Returns whether the join has fired. true if the join has fired.



hasFired
final protected synchronized boolean hasFired(int index)(Code)



hashCode
final public synchronized int hashCode()(Code)



isModified
final public synchronized boolean isModified()(Code)
Returns whether the join has been modified since it was last persisted. true if the join has been modified.



reset
final public synchronized void reset()(Code)
Resets the join to its initial state. The #getFiredCount 'firedcount' is unaffected by the reset operation.



shouldFire
abstract public boolean shouldFire(String transitionId)(Code)
Handles the activation of an afferent transition.
Parameters:
  transitionId - The ID of the transition that fired. true if the join fired.



toString
final public synchronized String toString()(Code)
