Class UML 2.5::ExpansionNode

Description:

An ExpansionNode is an ObjectNode used to indicate a collection input or output for an ExpansionRegion. A collection input of an ExpansionRegion contains a collection that is broken into its individual elements inside the region, whose content is executed once per element. A collection output of an ExpansionRegion combines individual elements produced by the execution of the region into a collection for use outside the region.

Properties:

regionAsInput : ExpansionRegion (0 1); -- source ExpansionNode
regionAsOutput : ExpansionRegion (0 1); -- source ExpansionNode
inState : State (0 *); -- source ObjectNode
isControlType : Boolean (1 1); -- source ObjectNode

Indicates whether the type of the ObjectNode is to be treated as representing control values that may traverse ControlFlows.
Default value: FALSE

ordering : ObjectNodeOrderingKind (1 1); -- source ObjectNode
selection : Behavior (0 1); -- source ObjectNode
upperBound : ValueSpecification (0 1); -- source ObjectNode

The maximum number of tokens that may be held by this ObjectNode. Tokens cannot flow into the ObjectNode if the upperBound is reached. If no upperBound is specified, then there is no limit on how many tokens the ObjectNode can hold.
