public class ActivityConnectorLink

extends WfLink

implements Externalizable

The ActivityConnectorLink associates steps to connectors. It knows how to interpret the result of the event-action mapping for each source event. A source step may be connected to many connectors and a destination connector may have many step sources.

Use the newActivityConnectorLink static factory method(s), not the ActivityConnectorLink constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.

Supported API: false

Extendable: false

boolean

hashCode
