Class UML 2.3::LoopNode

Description:

A loop node is a structured activity node that represents a loop with setup, test, and body sections.

Direct Superclasses: StructuredActivityNode

Direct Subclasses:

Class Precedence List: LoopNode, StructuredActivityNode, ActivityGroup, Action, ExecutableNode, ActivityNode, RedefinableElement, Namespace, NamedElement, Element

Properties:

bodyOutput : OutputPin (0 *); -- source LoopNode
bodyPart : ExecutableNode (0 *); -- source LoopNode
decider : OutputPin (1 1); -- source LoopNode
isTestedFirst : Boolean (1 1); -- source LoopNode
loopVariable : OutputPin (0 *); -- source LoopNode

A list of output pins that hold the values of the loop variables during an execution of the loop. When the test fails, the values are movied to the result pins of the loop.

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.
