ElementConstraints:
Signature: result_no_incoming() : Boolean;
Description: The result output pins have no incoming edges.
Expression: true
Signature: one_clause_with_executable_node() : Boolean;
Description: No ExecutableNode may appear in the test or body part of more than one
clause of a conditional node.
Expression: true
Signature: no_input_pins() : Boolean;
Description: A conditional node has no input pins.
Expression: true
Signature: matching_output_pins() : Boolean;
Description: Each clause of a conditional node must have the same number of bodyOutput
pins as the conditional node has result output pins, and each clause bodyOutput
pin must be compatible with the corresponding result pin (by positional
order) in type, multiplicity, ordering and uniqueness.
Expression: true
Signature: executable_nodes() : Boolean;
Description: The union of the ExecutabledNodes in the test and body parts of all clauses
must be the same as the subset of nodes contained in the ConditionalNode
(considered as a StructuredActivityNode) that are ExecutableNodes.
Expression: true
Signature: clause_no_predecessor() : Boolean;
Description: No two clauses within a ConditionalNode maybe predecessor clauses of each
other, either directly or indirectly.
Expression: true
Operations:
No additional operations.
