Constraints:

Signature: result_no_incoming() : Boolean;
Description: The result output pins have no incoming edges.
Expression: true

Signature: input_edges() : Boolean;
Description: Loop variable inputs must not have outgoing edges.
Expression: true

Signature: executable_nodes() : Boolean;
Description: The union of the ExecutableNodes in the setupPart, test and bodyPart of a LoopNode must be the same as the subset of nodes contained in the LoopNode (considered as a StructuredActivityNode) that are ExecutableNodes.
Expression: true

Signature: body_output_pins() : Boolean;
Description: The bodyOutput pins are output pins on actions in the body of the loop node.
Expression: true

Operations:

No additional operations.
