Alternatively, the joinSpec may consist of an Expression with the name of a single Boolean operator and no operands specified. In this case, the value of the joinSpec shall be given by applying the given operator to Boolean values indicating the presence (true) or absence (false) of offers on each incoming edge (with the ordering of the operands not specified).

[UML-2.5.1] In general, a ValueSpecification is a model element that is considered semantically to yield zero or more values.

[UML-2.5.1] Expressions are ValueSpecifications that specify values resulting from a computation.

[UML-2.5.1] An Interval is a ValueSpecification specified using two other ValueSpecifications, the min and the max.

[UML-2.5.1] a LiteralSpecification may be used in a ValueSpecificationAction to produce a constant value.

[UML-2.5.1] A LiteralUnlimitedNatural specifies a constant value of the PrimitiveType UnlimitedNatural.

[UML-2.5.1] A LiteralUnlimitedNatural is shown either as a sequence of digits or as an asterisk (*), where an asterisk denotes unlimited.

[UML-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.”

[UML-2.5.1] An OpaqueExpression specifies the computation of a set of values either in terms of a UML Behavior or based on a textual statement in a language other than UML.

[UML-2.5.1] A LiteralNull is intended to be used to explicitly model the lack of a value.

[UML-2.5.1] LiteralNull: In the context of a MultiplicityElement with a multiplicity lower bound of 0, this corresponds to the empty set (i.e., a set of no values). It is equivalent to specifying no values for the Element.

[UML-2.5.1] The notation for a LiteralNull varies depending on where it is used. It often appears as the word “null.” Other notations are described elsewhere for specific uses.

[UML-2.5.1] A LiteralString specifies a constant value of the PrimitiveType String. Though a String is specified as a sequence of characters, String values are considered to be primitive in UML, so their internal structure is not specified as part of UML semantics.

[UML-2.5.1] A LiteralString is shown as a sequence of characters within double quotes. The String value is the sequence of characters, not including the quotes. The character set used is unspecified.

[UML-2.5.1] A LiteralInteger specifies a constant value of the PrimitiveType Integer.

[UML-2.5.1] A LiteralInteger is shown as a sequence of digits representing the decimal numeral for the Integer value.

[UML-2.5.1] A LiteralBoolean specifies a constant value of the PrimitiveType Boolean.

[UML-2.5.1] A LiteralBoolean is shown as either the word “true” or the word “false,” corresponding to its value.

[UML-2.5.1] A LiteralReal specifies a constant value of the PrimitiveType Real.

[UML-2.5.1] A LiteralReal is shown in decimal notation or scientific notation.

The String value of a StringExpression is obtained by concatenating, in order, the String values of either the operands or the subExpressions, depending on which is given.
