Abstract Class UML 2.3::ObjectNode

Description:

Object nodes have support for token selection, limitation on the number of tokens, specifying the state required for tokens, and carrying control values.

Direct Superclasses: TypedElement, ActivityNode

Direct Subclasses: Pin, ExpansionNode, CentralBufferNode, ActivityParameterNode

Class Precedence List: ObjectNode, TypedElement, ActivityNode, RedefinableElement, NamedElement, Element

Constraints:

Signature: selection_behavior() : Boolean;
Description: If an object node has a selection behavior, then the ordering of the object node is ordered, and vice versa.
Expression: true

Signature: object_flow_edges() : Boolean;
Description: All edges coming into or going out of object nodes must be object flow edges.
Expression: true

Signature: input_output_parameter() : Boolean;
Description: A selection behavior has one input parameter and one output parameter. The input parameter must be a bag of elements of the same type as the object node or a supertype of the type of object node. The output parameter must be the same or a subtype of the type of object node. The behavior cannot have side effects.
Expression: true

Operations:

No additional operations.
