IEnumCurve.Clone Method
Returns a copy of this enumerator positioned at the same segment.
Public Function Clone ( _
) As IEnumCurve
public IEnumCurve Clone (
);
Description
Returns a duplicate copy of the IEnumCurve. The distance iterator location along the segment enumeration is maintained.
IEnumCurve.CurveDistance Property
The current distance from the start of the curve.
Public ReadOnly Property CurveDistance As Double
public double CurveDistance {get;}
Description
Returns the distance from the start of the curve to the current location of the distance iterator.
Remarks
Note: Gaps between parts are ignored in distance computations.
IEnumCurve.GetSubcurve Method
Extracts a portion of this curve into a new curve.
Public Function GetSubcurve ( _
ByVal fromDistance As Double, _
ByVal toDistance As Double, _
ByVal asRatio As Boolean _
) As ICurve
public ICurve GetSubcurve (
double fromDistance,
double toDistance,
bool asRatio
);
Description
The GetSubCurve method returns a polyline or path object corresponding to a portion of the input curve. If the ISegmentCollection points to a IPolyline or a IPolygon then the output is of type IPolyline, otherwise the output is of type IPath.
Remarks
Note: Gaps between parts are ignored in distance computations.
Parameters description:
fromDistance: Input Double. Input distance that determines where the subcurve should start. The value of that parameter should be in map unit unless asRatio is true.toDistance: Input Double. Input distance that determines where the subcurve should stop. The value of that parameter should be in map unit unless asRatio is true.asRatio: Input Boolean. The asRatio determines if the input distances should be interpreted as map unit asRatio = false distance or parametric distance asRatio = True (0 = distance of 0, 1 = full length of the curve).
IEnumCurve.Next Method
Moves iterator to a specified distance along the curve.
Public Sub Next ( _
ByVal distance As Double _
)
public void Next (
double distance
);
Description
Advances the distance iterator to a specified distance along the enumerated curve.
Remarks
Note: Gaps between parts are ignored in distance computations.
IEnumCurve.PartIndex Property
The current part index.
Public ReadOnly Property PartIndex As Integer
public int PartIndex {get;}
Description
Returns the Part Index of the part referenced by the current location of the distance iterator.
IEnumCurve.Reset Method
Resets the iterator to the start of the curve.
Public Sub Reset ( _
)
public void Reset (
);
Description
Returns the distance iterator to the beginning of the enumerated curve. The distance along the curve is returned to the zero distance.
IEnumCurve.Segment Property
The segment covering the current distance of this curve iterator.
Public ReadOnly Property Segment As ISegment
public ISegment Segment {get;}
Description
Returns the segment at the current distance along the enumerated curve referenced by the distance iterator.
IEnumCurve.SegmentDistance Property
The distance within the current segment of the current distance of this curve iterator.
Public ReadOnly Property SegmentDistance As Double
public double SegmentDistance {get;}
Description
Returns the distance from the From Point of the current Segment to the location of the distance iterator.
IEnumCurve.SegmentIndex Property
The current segment index within the current part.
Public ReadOnly Property SegmentIndex As Integer
public int SegmentIndex {get;}
Description
Returns the index of the Segment referenced by the current location of the distance iterator. The Segment Index is relative to the Part to which the segment belongs.
IEnumCurve.StopOptions Property
Stop options for the distance iterator.
Public Property StopOptions As esriCurveIteratorEnum
public esriCurveIteratorEnum StopOptions {get; set;}
Description
Returns and sets the current esriCurveIteratorEnum stop conditions for the distance iterator.
IEnumCurve.StopReason Property
The reason for the current position of the distance iterator.
Public ReadOnly Property StopReason As esriCurveIteratorEnum
public esriCurveIteratorEnum StopReason {get;}
Description
Returns an esriCurveIteratorEnum that describes the reason for the current location of the distance iterator.
Remarks
Note: The StopReason returns value different than esriCurveIteratorNoStop only if the enumerator wasn't explicitly set to the end points of a part. For example, setting the enumerator to a distance of zero will not return esriCurveIteratorStopAtPartFrom even if that option was set with the StopOptions property.
