Constructors

Properties

	Name	Description
	BypassDemandLoading	Allows the walker to bypass demand loading while traversing (Inherited from ElementWalker.)
	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
	BeginTraverseElement	Virtual method called when the walker is about visit the specified element and its related elements. (Inherited from DepthFirstElementWalker.)
	DoTraverse	Traverse the model starting at the specified starting element. (Inherited from DepthFirstElementWalker.)
	EndTraverseElement	Virtual method indicates that the walker has finished traversing into the specified element. (Inherited from DepthFirstElementWalker.)
	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.)
	GetRelatedElements	Get the list of immediately neighboring elements that should be visited, in the order in which they should be visited. (Overrides DepthFirstElementWalker.GetRelatedElements(ModelElement).)
	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.)

Remarks

You can inherit from this class to define a walker. Override GetRelatedElements.
