Method Detail

getActions

public org.apache.lenya.workflow.Action[] getActions()

Returns the actions which are assigned tothis transition.

Specified by:

getActions in interface org.apache.lenya.workflow.Transition

---

addAction

public void addAction(org.apache.lenya.workflow.Action action)

Assigns an action to this transition.

---

getConditions

public org.apache.lenya.workflow.Condition[] getConditions()

Returns the conditions which are assigned to this transition.

---

addCondition

public void addCondition(org.apache.lenya.workflow.Condition condition)

Assigns a condition to this transition.

---

getEvent

public org.apache.lenya.workflow.Event getEvent()

Returns the event which invokes this transition.

Specified by:

getEvent in interface org.apache.lenya.workflow.Transition

---

setEvent

public void setEvent(org.apache.lenya.workflow.Event anEvent)

Sets the event to invoke this transition.

---

getSource

public StateImpl getSource()

Returns the source state of this transition.

---

getDestination

public StateImpl getDestination()

Returns the destination state of this transition.

---

canFire

public boolean canFire(org.apache.lenya.workflow.Situation situation,
                       org.apache.lenya.workflow.WorkflowInstance instance)
                throws org.apache.lenya.workflow.WorkflowException

Returns if the transition can fire in a certain situation.

Specified by:

canFire in interface org.apache.lenya.workflow.Transition

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

isSynchronized

public boolean isSynchronized()

Returns if this transition is synchronized.

Specified by:

isSynchronized in interface org.apache.lenya.workflow.Transition

---

setSynchronized

protected void setSynchronized(boolean isSynchronized)

Sets if this transition is synchronized.
