Constraints:

Signature: same_type() : Boolean;
Description: The type of an activity parameter node is the same as the type of its parameter.
Expression: true

Signature: no_outgoing_edges() : Boolean;
Description: Activity parameter object nodes with no outgoing edges and one or more incoming edges must have a parameter with out, inout, or return direction.
Expression: true

Signature: no_incoming_edges() : Boolean;
Description: Activity parameter object nodes with no incoming edges and one or more outgoing edges must have a parameter with in or inout direction.
Expression: true

Signature: no_edges() : Boolean;
Description: An activity parameter node may have all incoming edges or all outgoing edges, but it must not have both incoming and outgoing edges.
Expression: true

Signature: maximum_two_parameter_nodes() : Boolean;
Description: A parameter with direction inout must have at most two activity parameter nodes in an activity, one with incoming flows and one with outgoing flows.
Expression: true

Signature: maximum_one_parameter_node() : Boolean;
Description: A parameter with direction other than inout must have at most one activity parameter node in an activity.
Expression: true

Signature: has_parameters() : Boolean;
Description: Activity parameter nodes must have parameters from the containing activity.
Expression: true
