B.4.13 HasCause ToC Previous Next index

The HasCause ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences.

The semantic of this ReferenceType is to point from a Transition to something that causes the Transition. In this annex we only define Methods as Causes. However, the ReferenceType is not restricted to point to Methods. The referenced Methods can, but do not have to point to a Method of the StateMachineType. For example, it is allowed to point to a server-wide restart Method leading the state machine to go into its initial state.

The SourceNode of this ReferenceType shall be an Object of the ObjectType TransitionType or one of its subtypes. The TargetNode can be of any NodeClass.

The representation of the HasCause ReferenceType in the AddressSpace is specified in Table B.12.
