Method Detail

getName

java.lang.String getName()

the short display name given to this element.

getDescription

java.lang.String getDescription()

the long description.

getParent

ObservableElement getParent()

by default, this implementation returns null, but this is overwritten in Node and Transition to represent the parent in the hierarchical structure of the process. This hierarchical structure is used for event propagation.

getEvents

java.util.Map<java.lang.String,Event> getEvents()

listeners, partitioned by event name. Beware: the actual member is returned. No copy is made.

getEvent

Event getEvent(java.lang.String eventName)

listeners for a specific event.

hasEvent

boolean hasEvent(java.lang.String eventName)

check for presence of a given eventName.
