The ElementClosureWalker type exposes the following members.

Constructors

	Name	Description
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>, IEnumerable<DomainRoleInfo>)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>, IEnumerable<DomainRoleInfo>, IList<DomainRoleInfo>)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>, Boolean, IEnumerable<DomainRoleInfo>, Boolean)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>, Boolean, IEnumerable<DomainRoleInfo>, IEnumerable<DomainRoleInfo>, IList<ModelElement>)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.
	ElementClosureWalker(Partition, ClosureType, ICollection<ModelElement>, Boolean, IEnumerable<DomainRoleInfo>, IList<DomainRoleInfo>, Boolean)	Constructor that creates an ElementVisitor and calls base. This results in breadth first traversal, pre-Order visitation of the graph with element links.

Properties

	Name	Description
	BypassDemandLoading	Allows the walker to bypass demand loading while traversing (Inherited from ElementWalker.)
	ClosureList	Resultant List of elements that form the closure
	Context	Offer a context object for general use by the closure visitors. Use it to store tag/value pairs while building closures.
	Filter	Get or set the IElementVisitorFilter for use during traversal (Inherited from ElementWalker.)
	IncludeLinks	Returns true if the walker will include element links in calls to the visitor function (Inherited from ElementWalker.)
	InternalElementList	Get the internal list of elements that will be visited (Inherited from ElementWalker.)
	Store	Get the internal list of elements that will be visited (Inherited from ElementWalker.)
	Visitor	Get or set the IElementVisitor for use during traversal (Inherited from ElementWalker.)

Methods

	Name	Description
	DoTraverse	Visit the elements defined by the visitor and filter. (Inherited from BreadthFirstRolePlayerFirstElementWalker.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MarkForRemovalFromInternalElementList	Mark an element for removal from the InternalElementList. We mark first and remove later at the end so that the indices remain valid. When marking elements as visited, we store an index in the hashtable which tells us the order that the element was visited in. If the elements were put into the InternalElementList in that order, we can find the element easily using the index. If not a linear search will be used to find the element. (Inherited from ElementWalker.)
	MarkVisited	Mark an element as having been already visited (Inherited from ElementWalker.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveMarkedElements	Removes the elements that are marked for removal. Call this at the end of the traversal so that the indices in alreadyVisited remain valid. (Inherited from ElementWalker.)
	Reset	Reset the visitor so that it can start traversing again. This is necessary to clear out the internal list of previously visited elements. (Inherited from ElementWalker.)
	ShouldVisitLinkAgain	True if the link has been visited before the currentElement (one of its roleplayers) was visited. (Inherited from ElementWalker.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Traverse(ModelElement)	Traverse the model starting at the specified starting element. (Inherited from ElementWalker.)
	Traverse(ICollection<ModelElement>)	Traverse the model starting at the specified starting elements. (Inherited from ElementWalker.)
	Visited	determines if the given element has been visited or not (Inherited from ElementWalker.)
