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.

ElementConstraints:
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.
