ITopologyElement Interface

Provides access to the functionality present in all topology elements. ITopologyEdge and ITopologyNode inherit from this interface.

Description

A TopologyElement consists of TopologyNode and TopologyEdge, which corresponds to points and lines, respectively, in the feature space.

Members

	Name	Description
	Geometry	The geometry of the topology element.
	IsDeleted	Indicates if this element has been deleted from its containing topology graph.
	IsSelected	Indicates if this element is part of its containing topology graph's selected set.
	Parents	The set of parents (features) of this topology element.
	QueryGeometry	Copies the element's geometry into the specified geometry.
	Visited	Indicates if the topology element has been visited.

ITopologyElement.Geometry Property

The geometry of the topology element.

Public ReadOnly Property Geometry As IGeometry

public IGeometry Geometry {get;}

ITopologyElement.IsDeleted Property

Indicates if this element has been deleted from its containing topology graph.

Public ReadOnly Property IsDeleted As Boolean

public bool IsDeleted {get;}

ITopologyElement.IsSelected Property

Indicates if this element is part of its containing topology graph's selected set.

Public ReadOnly Property IsSelected As Boolean

public bool IsSelected {get;}

ITopologyElement.Parents Property

The set of parents (features) of this topology element.

Public ReadOnly Property Parents As IEnumTopologyParent

public IEnumTopologyParent Parents {get;}

ITopologyElement.QueryGeometry Method

Copies the element's geometry into the specified geometry.

Public Sub QueryGeometry ( _
    ByVal Geometry As IGeometry _
)

public void QueryGeometry (
    IGeometry Geometry
);

Remarks

The Geometry parameter must be an instance of an appropriate type of geometry for the topology element being called. For example, if the topology element is a node, a new point should be created and passed as the parameter. If the topology element is an edge, a new polyline should be created and passed as the parameter.

ITopologyElement.Visited Property

Indicates if the topology element has been visited.

Public Property Visited As Boolean

public bool Visited {get; set;}
