Method Summary

long	getDbid() the meaningless database primary key
String	getName() the short display name given to this element.
ObservableElement	getParent() the enclosing node or the process definition
OpenProcessDefinition	getProcessDefinition() the process definition to which this process element belongs
Object	getProperty(String key) the property value for the given key or null if no such configuration key is present.
Set<String>	getPropertyKeys() the set of available property keys or an empty set in case there are no keys.
boolean	hasEvent(String eventName) indicates if the given event is defined no this element.

Method Detail

getDbid

long getDbid()

the meaningless database primary key

getName

String getName()

the short display name given to this element.

getProcessDefinition

OpenProcessDefinition getProcessDefinition()

the process definition to which this process element belongs

getProperty

Object getProperty(String key)

the property value for the given key or null if no such configuration key is present. This is extra static configuration information that can be associated to a process element. Process languages can use this to store configuration properties for extensions in it. That way, these extensions can be added without changing the process model or the database schema. Examples of extensions that may use these configuration properties are simulation, predictive scheduling, graphical information,...

getPropertyKeys

Set<String> getPropertyKeys()

the set of available property keys or an empty set in case there are no keys.

hasEvent

boolean hasEvent(String eventName)

indicates if the given event is defined no this element. This method only looks in this observable element and it will not search the parent hierarchy for the given event.

getParent

ObservableElement getParent()

the enclosing node or the process definition
