If the upperBound evaluates to *, then there is no limit on the number of tokens the ObjectNode may hold. Source Unified Modeling Language 2.5.1
If the removal of one or more tokens brings the number of tokens held below the evaluated upperBound, then the ObjectNode may accept any pending offers up to the limit of the upperBound. Source Unified Modeling Language 2.5.1
If the number of tokens already held by the ObjectNode is greater than or equal to the evaluated upperBound, then the ObjectNode shall not accept any further tokens until some of the ones it is holding are removed. Source Unified Modeling Language 2.5.1
An ObjectNode may not contain more tokens than specified by its upperBound, if any. If an ObjectNode has an upperBound, then this ValueSpecification shall evaluate to an UnlimitedNatural value. The upperBound is evaluated each time a token is offered ... Source Unified Modeling Language 2.5.1
Note that “unlimited” denotes the lack of a limit on the value of some element (such as a multiplicity upper bound), not a value of “infinity.” Source Unified Modeling Language 2.5.1
A LiteralUnlimitedNatural is shown either as a sequence of digits or as an asterisk (*), where an asterisk denotes unlimited. Source Unified Modeling Language 2.5.1
A LiteralUnlimitedNatural specifies a constant value of the PrimitiveType UnlimitedNatural. Source Unified Modeling Language 2.5.1
A value of unlimited (“*”) for the insertion point means to insert the new value at the end of the sequence. Source Unified Modeling Language 2.5.1
If the insertAt InputPin is present, it has type UnlimitedNatural and multiplicity 1..1 Source Unified Modeling Language 2.5.1
