ObservableElementImpl

public ObservableElementImpl()

Method Detail

getParent

public ObservableElementImpl getParent()

Description copied from interface: ObservableElement

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.

Specified by:

getParent in interface ObservableElement

getEvent

public EventImpl getEvent(java.lang.String eventName)

Description copied from interface: ObservableElement

listeners for a specific event.

Specified by:

getEvent in interface ObservableElement

hasEvent

public boolean hasEvent(java.lang.String eventName)

Description copied from interface: ObservableElement

check for presence of a given eventName.

Specified by:

hasEvent in interface ObservableElement

createEvent

public EventImpl createEvent(java.lang.String eventName)

event factory method that also establishes the bidirectional relation.

addEvent

public EventImpl addEvent(EventImpl event)

add an event to this processDefinition element.

Throws:

java.lang.NullPointerException - if event is null.

getName

public java.lang.String getName()

Description copied from interface: ObservableElement

the short display name given to this element.

Specified by:

getName in interface ObservableElement

setName

public void setName(java.lang.String name)

getDescription

public java.lang.String getDescription()

Description copied from interface: ObservableElement

the long description.

Specified by:

getDescription in interface ObservableElement

setDescription

public void setDescription(java.lang.String description)

getEvents

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

Description copied from interface: ObservableElement

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

Specified by:

getEvents in interface ObservableElement

setEvents

public void setEvents(java.util.Map<java.lang.String,EventImpl> events)
