The Namespace Class classifies and characterizes Elements that can contain other Elements. Along with containing the Elements, a Namespace defines a namespace, the allowable set of names and the naming constraints, for these elements.

Subclasses of the Namespace Class have mechanisms for effectively extending their namespace, without actually containing additional Elements. Thus Namespace can be viewed in terms of its two roles, as a container and as a namespace mechanism. Because only subclasses extend the namespace, the namespace and contents are coincident in the definition of the Namespace Class. Each Namespace has four collections (the latter three derivable) that are used in the MOF Model’s Constraints. These collections are:

• The contents (also called the direct contents), which are defined by the contents
  reference.


• All contents, the transitive closure on the contents reference.


• The extended namespace (the contents plus elements included by extension), which
  Namespace subclasses accomplish through generalization and importation.


• The extended contents (the transitive closure on the contents reference applied to
  the extended namespace).

Operations
Class NamespaceFindElementsByTypeResult	findElementsByType	Returns all the Elements identified by the contents reference defined for this Namespace that are of the Class supplied. The returned list of Elements is a subset of the Elements contained by this Namespace. This operation can either return only those Elements that exactly match the specified class or those Elements that are instances of the specified class and one or more of its subclasses. Because Element is an abstract class, invoking this operation with the ofType argument specified as Element and the includeSubtypes argument set to false returns an empty list. Because Element is the base type for all instances that can be contained by a Namespace, invoking the operation with the ofType argument specified as Element, and includeSubtypes set to true, returns all the contained elements of the Namespace. Returns all the ModelElements identified by the contents reference defined for this Namespace that are of the Class supplied. The returned list of ModelElements is a subset of the ModelElements contained by this Namespace. This operation can either return only those ModelElements that exactly match the specified class or those ModelElements that are instances of the specified class and one or more of its subclasses. Because ModelElement is an abstract class, invoking this operation with the ofType argument specified as ModelElement and the includeSubtypes argument set to false returns an empty list. Because ModelElement is the base type for all instances which can be contained by a Namespace, Invoking the operation with the ofType argument specified as ModelElement, and includeSubtypes set to true, returns all the contained elements of the Namespace.
Class NamespaceLookupElementResult	lookupElement	Searches for an element contained by this Namespace whose name is precisely equal (as a string) to the supplied name. The operation either returns an Element that satisfies the above, or raises ServiceException (NameNotFound).
Class NamespaceResolveQualifiedNameResult	resolveQualifiedName	Searches for an Element contained within this Namespace that is identified by the supplied qualifiedName. The qualifiedName is interpreted as a 'path' starting from this Namespace.

 findElementsByType

public Class NamespaceFindElementsByTypeResult findElementsByType( Primitive Type boolean, Primitive Type string  )

Returns all the Elements identified by the contents reference defined for this Namespace that are of the Class supplied. The returned list of Elements is a subset of the Elements contained by this Namespace. This operation can either return only those Elements that exactly match the specified class or those Elements that are instances of the specified class and one or more of its subclasses.

Because Element is an abstract class, invoking this operation with the ofType argument specified as Element and the includeSubtypes argument set to false returns an empty list. Because Element is the base type for all instances that can be contained by a Namespace, invoking the operation with the ofType argument specified as Element, and includeSubtypes set to true, returns all the contained elements of the Namespace.


Returns all the ModelElements identified by the contents reference defined for this
Namespace that are of the Class supplied. The returned list of ModelElements is a subset of
the ModelElements contained by this Namespace. This operation can either return only
those ModelElements that exactly match the specified class or those ModelElements that
are instances of the specified class and one or more of its subclasses.
Because ModelElement is an abstract class, invoking this operation with the ofType
argument specified as ModelElement and the includeSubtypes argument set to false returns
an empty list. Because ModelElement is the base type for all instances which can be
contained by a Namespace, Invoking the operation with the ofType argument specified as
ModelElement, and includeSubtypes set to true, returns all the contained elements of the
Namespace.
