ISegmentGraphCursor Interface

Provides access to members that define and manipulate a way of navigating over segments topologically structured within a segment graph.

Members

	Name	Description
	CurrentTrace	The current trace - a history of MoveTo/s and FinishMoveTo's within the segment graph since it was created or since the last call to Reset on this cursor.
	FinishMoveTo	Moves from the current edge to the adjacent edge closest to newLocation. Used only when MoveTo returns false.
	Location	The current location of the SegmentGraphCursor.
	MoveTo	Moves from the current edge to an adjacent edge closest to newLocation. Returns true when that move is clear, or false if it crosses a multi-way branch (in that case, then use FinishMoveTo).
	QueryLocation	Copies the current location of the SegmentGraphCursor into the specified point.
	Reset	Resets the location of the SegmentGraphCursor to a specified StartPoint.

ISegmentGraphCursor.CurrentTrace Property

The current trace - a history of MoveTo/s and FinishMoveTo's within the segment graph since it was created or since the last call to Reset on this cursor.

Public ReadOnly Property CurrentTrace As IPolyline

public IPolyline CurrentTrace {get;}

ISegmentGraphCursor.FinishMoveTo Method

Moves from the current edge to the adjacent edge closest to newLocation. Used only when MoveTo returns false.

Public Sub FinishMoveTo ( _
    ByVal newLocation As IPoint _
)

public void FinishMoveTo (
    IPoint newLocation
);

ISegmentGraphCursor.Location Property

The current location of the SegmentGraphCursor.

Public ReadOnly Property Location As IPoint

public IPoint Location {get;}

ISegmentGraphCursor.MoveTo Method

Moves from the current edge to an adjacent edge closest to newLocation. Returns true when that move is clear, or false if it crosses a multi-way branch (in that case, then use FinishMoveTo).

Public Function MoveTo ( _
    ByVal newLocation As IPoint _
) As Boolean

public bool MoveTo (
    IPoint newLocation
);

ISegmentGraphCursor.QueryLocation Method

Copies the current location of the SegmentGraphCursor into the specified point.

Public Sub QueryLocation ( _
    ByVal currentGraphLocation As IPoint _
)

public void QueryLocation (
    IPoint currentGraphLocation
);

ISegmentGraphCursor.Reset Method

Resets the location of the SegmentGraphCursor to a specified StartPoint.

Public Sub Reset ( _
    ByVal startPoint As IPoint _
)

public void Reset (
    IPoint startPoint
);
