Class UML 2.5::StringExpression
Description:
A StringExpression is an Expression that specifies a String value that
is derived by concatenating a sequence of operands with String values or
a sequence of subExpressions, some of which might be template parameters.

NamedElementA name that allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
Namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.

Operations:
Signature: stringValue() : String;
Description: The query stringValue() returns the String resulting from concatenating,
in order, all the component String values of all the operands or subExpressions
that are part of the StringExpression.
Expression: result = (if subExpression->notEmpty() then subExpression->iterate(se; stringValue: String = '' | stringValue.concat(se.stringValue())) else operand->iterate(op; stringValue: String = '' | stringValue.concat(op.stringValue())) endif)
