ElementConstraints:
No additional constraints.
Operations:
Signature: membersAreDistinguishable() : Boolean;
Description: The Boolean query membersAreDistinguishable() determines whether all of
the Namespace's members are distinguishable within it.
Expression: result = (member->forAll( memb | member->excluding(memb)->forAll(other | memb.isDistinguishableFrom(other, self))))
Signature: importedMember.1() : PackageableElement;
Description: The importedMember property is derived as the PackageableElements that
are members of this Namespace as a result of either PackageImports or ElementImports.
Expression: result = (self.importMembers(elementImport.importedElement->asSet()->union(packageImport.importedPackage->collect(p | p.visibleMembers()))->asSet()))
Signature: importMembers(imps : PackageableElement; ) : PackageableElement;
Description: The query importMembers() defines which of a set of PackageableElements
are actually imported into the Namespace. This excludes hidden ones, i.e.,
those which have names that conflict with names of ownedMembers, and it
also excludes PackageableElements that would have the indistinguishable
names when imported.
Expression: result = (self.excludeCollisions(imps)->select(imp | self.ownedMember->forAll(mem | imp.isDistinguishableFrom(mem, self))))
Signature: getNamesOfMember(element : NamedElement; ) : String;
Description: The query getNamesOfMember() gives a set of all of the names that a member
would have in a Namespace, taking importing into account. In general a
member can have multiple names in a Namespace if it is imported more than
once with different aliases.
Expression: result = (if self.ownedMember ->includes(element) then Set{element.name} else let elementImports : Set(ElementImport) = self.elementImport->select(ei | ei.importedElement = element) in if elementImports->notEmpty() then elementImports->collect(el | el.getName())->asSet() else self.packageImport->select(pi | pi.importedPackage.visibleMembers().oclAsType(NamedElement)->includes(element))-> collect(pi | pi.importedPackage.getNamesOfMember(element))->asSet() endif endif)
Signature: excludeCollisions(imps : PackageableElement; ) : PackageableElement;
Description: The query excludeCollisions() excludes from a set of PackageableElements
any that would not be distinguishable from each other in this Namespace.
Expression: result = (imps->reject(imp1 | imps->exists(imp2 | not imp1.isDistinguishableFrom(imp2, self))))
