ITopologyGraph2 Interface

Provides access to members that control the topology graph. Note: the ITopologyGraph2 interface has been superseded byITopologyGraph4. Please consider using the more recent version.

Members

	All Properties Methods Inherited Non-inherited	Description
	Build	Creates topo elements from all topology feature classes covering the specified map extent.
	BuildExtent	The extent used to build the graph.
	DeleteEdge	Deletes the specified edge from its containing topology graph.
	DeletePseudoNodesFromSelection	Removes pseudo-nodes by combining edges incident on such nodes. Edges and nodes in the current selection are considered.
	Edges	The enumerator that provides access to all the edges.
	EdgeSelection	The enumerator for the selected edges of the topology.
	EnumHitTest	Locates all elements of the graph within searchRadius units of the query point; whichElements is a bitwise combination of esriTopologyElement values.
	Extent	The current extent of all topological elements in the graph. This may be different than the extent used to build the graph.
	GetParentEdges	Returns the set of edges corresponding to the specified polyline or polygon feature.
	GetParentGeometry	Creates a geometry corresponding to the current set of edges/nodes owned by the specified parent.
	GetParentNodes	Returns the set of nodes corresponding to the specified point or multipoint feature.
	GetSelectionFeedback	Creates a display feedback object to indicate the effect of a TransformSelection operation on the selected elements; whichElements is a bitwise combination of esriTopologyElement values.
	GetSplitMoveNodeFeedback	Creates a display feedback object to indicate the effect of a SplitMoveNode operation on the specified node.
	HasElement	Indicates if the topology graph contains the specified element.
	HasPseudoNodes	Indicates if the topology graph contains pseudo nodes.
	HitTest	Locates an element of the graph nearest to the query point that is also within searchRadius units of it; whichElements is a bitwise combination of esriTopologyElement values.
	HitTestSelection	Locates an element of the graph's selection nearest to the query point that is also within searchRadius units of it; whichElements is a bitwise combination of esriTopologyElement values.
	IsPosting	Indicates if the topology graph is posting.
	Nodes	The enumerator that provides access to all the nodes.
	NodeSelection	The enumerator for the selected nodes of the topology.
	Post	Posts changes to topology elements back to their originating features. Must be used within an edit session and edit operation.
	ReshapeEdgeGeometry	Reshapes (and possibly reinterpolates) the geometry of the specified edge.
	Select	Adds the specified element to the selected subset of the graph.
	SelectByGeometry	Selects nodes and/or edges that intersect the specified geometry; whichElements is a bitwise combination of esriTopologyElement values.
	SelectionCount	The count of selected elements of the specified types; whichElements is a bitwise combination of esriTopologyElement values.
	SelectionExtent	The extent of the selected subset of the graph, optionally includes extent of all edges incident on selected nodes (or on nodes incident on selected edges); whichElements is a bitwise combination of esriTopologyElement values.
	SelectionParents	The feature class and oid of each parent of the selected set of elements.
	SetEdgeGeometry	Assigns the path geometry to the specified edge. Reinterpolatex vertex attributes for the edge if any exist.
	SetEmpty	Removes all topological elements from the graph. Any client-side references to topo elements that came from this graph should be released.
	SetParentSelected	Selects parents of edges. SUbsequent edits to those edges will only be posted back to selected parents.
	SetSelectionEmpty	Clears the specified selection set: whichType is a bitwise combination of esriTopologyNode, esriTopologyEdge.
	SplitEdgeAtDistance	Adds a pseudo-node to the edge at the specified distance along the edge. The node gets created at an existing vertex if one is located within the specified tolerance.
	SplitEdgeAtPoint	Adds a pseudo-node to the edge at the point on the edge closest to the input point. The node gets created at an existing vertex if one is located within the specified tolerance of the split point.
	SplitMoveNode	Change graph connectivity: Moves the specified node, along with any selected edges incident on it. A copy of the node, along with unselected edges, remains in the original location.
	TransformSelection	Applies the specified transformation to the selected elements of the graph.
