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
);
