Class Namespace
A namespace has the ability to import either individial members or all members of a package, thereby making it possible to refer to those named elements without qualification in the importing namespace. In the case of conflicts, it is necessary to use qualified names or aliases to disambiguate the referenced elements.

Methods
ExcludeCollisions(IEnumerable<IPackageableElement>)
The query excludeCollisions() excludes from a set of PackageableElements any that would not be distinguishable from each other in this namespace. result = imps->reject(imp1 | imps.exists(imp2 | not imp1.isDistinguishableFrom(imp2, self)))
public ISetExpression<IPackageableElement> ExcludeCollisions(IEnumerable<IPackageableElement> imps)Parameters
Returns
GetClass()
Gets the Class for this model element
public override IClass GetClass()Returns
GetCollectionForFeature(string)
Gets the Model element collection for the given feature
protected override IList GetCollectionForFeature(string feature)Parameters
featurestringThe requested feature
Returns
- IList
A non-generic list of elements
GetCompositionName(object)
Gets the property name for the given container
protected override string GetCompositionName(object container)Parameters
containerobjectThe container object
Returns
- string
The name of the respective container reference
GetImportedMembers()
The importedMember property is derived from the ElementImports and the PackageImports. References the PackageableElements that are members of this Namespace as a result of either PackageImports or ElementImports. result = self.importMembers(self.elementImport.importedElement.asSet()->union(self.packageImport.importedPackage->collect(p | p.visibleMembers())))
public ISetExpression<IPackageableElement> GetImportedMembers()Returns
GetModelElementForReference(string, int)
Resolves the given URI to a child model element
protected override IModelElement GetModelElementForReference(string reference, int index)Parameters
Returns
- IModelElement
The model element or null if it could not be found
GetNamesOfMember(INamedElement)
The query getNamesOfMember() is overridden to take account of importing. It gives back the set of names that an element would have in an importing namespace, either because it is owned, or if not owned then imported individually, or if not individually then from a package. result = if self.ownedMember->includes(element) then Set{}->include(element.name) else let elementImports: ElementImport = self.elementImport->select(ei | ei.importedElement = element) in if elementImports->notEmpty() then elementImports->collect(el | el.getName()) else self.packageImport->select(pi | pi.importedPackage.visibleMembers()->includes(element))->collect(pi | pi.importedPackage.getNamesOfMember(element)) endif endif
public ISetExpression<string> GetNamesOfMember(INamedElement element)Parameters
elementINamedElement
Returns
GetRelativePathForNonIdentifiedChild(IModelElement)
Gets the relative URI fragment for the given child model element
protected override string GetRelativePathForNonIdentifiedChild(IModelElement element)Parameters
elementIModelElementThe element that should be looked for
Returns
- string
A fragment of the relative URI
ImportMembers(IEnumerable<IPackageableElement>)
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 owned members, and also excludes elements which would have the same name when imported. result = self.excludeCollisions(imps)->select(imp | self.ownedMember->forAll(mem | mem.imp.isDistinguishableFrom(mem, self)))
public ISetExpression<IPackageableElement> ImportMembers(IEnumerable<IPackageableElement> imps)Parameters
Returns
MembersAreDistinguishable()
The Boolean query membersAreDistinguishable() determines whether all of the namespace's members are distinguishable within it. result = self.member->forAll( memb | self.member->excluding(memb)->forAll(other | memb.isDistinguishableFrom(other, self)))
public bool MembersAreDistinguishable()Returns
Members_are_distinguishable(object, object)
All the members of a Namespace are distinguishable within it. membersAreDistinguishable()
public bool Members_are_distinguishable(object diagnostics, object context)
