public abstract class ElementWalker

NameDescription
System_CAPS_protmethodElementWalker(IElementVisitor, IElementVisitorFilter)

Constructor that takes an ElementVisitor.

System_CAPS_protmethodElementWalker(IElementVisitor, IElementVisitorFilter, Boolean)

Constructor that takes an ElementVisitor.

NameDescription
System_CAPS_pubpropertyBypassDemandLoading

Allows the walker to bypass demand loading while traversing

System_CAPS_pubpropertyFilter

Get or set the IElementVisitorFilter for use during traversal

System_CAPS_pubpropertyIncludeLinks

Returns true if the walker will include element links in calls to the visitor function

System_CAPS_pubpropertyInternalElementList

Get the internal list of elements that will be visited

System_CAPS_pubpropertyStore

Get the internal list of elements that will be visited

System_CAPS_pubpropertyVisitor

Get or set the IElementVisitor for use during traversal

NameDescription
System_CAPS_pubmethodDoTraverse(ModelElement)

Traverse the model starting at the specified starting element.

System_CAPS_pubmethodEquals(Object)

(Inherited from Object.)

System_CAPS_protmethodFinalize()

(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

(Inherited from Object.)

System_CAPS_pubmethodGetType()

(Inherited from Object.)

System_CAPS_protmethodMarkForRemovalFromInternalElementList(ModelElement)

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.

System_CAPS_protmethodMarkVisited(ModelElement)

Mark an element as having been already visited

System_CAPS_protmethodMemberwiseClone()

(Inherited from Object.)

System_CAPS_protmethodRemoveMarkedElements()

Removes the elements that are marked for removal. Call this at the end of the traversal so that the indices in alreadyVisited remain valid.

System_CAPS_pubmethodReset()

Reset the visitor so that it can start traversing again. This is necessary to clear out the internal list of previously visited elements.

System_CAPS_protmethodShouldVisitLinkAgain(ElementLink, ModelElement)

True if the link has been visited before the currentElement (one of its roleplayers) was visited.

System_CAPS_pubmethodToString()

(Inherited from Object.)

System_CAPS_pubmethodTraverse(ICollection<ModelElement>)

Traverse the model starting at the specified starting elements.

System_CAPS_pubmethodTraverse(ModelElement)

Traverse the model starting at the specified starting element.

System_CAPS_pubmethodVisited(ModelElement)

determines if the given element has been visited or not
