com.esri.arcgis.geometry
Interface IMSegmentation2

All Superinterfaces:
IMCollection, IMSegmentation, Serializable
All Known Subinterfaces:
IMSegmentation3, IMSegmentation4
All Known Implementing Classes:
Polyline
public interface IMSegmentation2
extends IMSegmentation, Serializable

Provides access to additional linear referencing operations on polylines.

Superseded By

IMSegmentation3

Remarks

The IMSegmentation2 interface (like the IMSegmenation interface) also provides methods designed to work with the dynamic segmentation functionality in ArcObjects. These methods offer extended ways to interpolate and update the m attributes on a PolyLine, by cumulative distance and also by existing m values.

Method Detail

setMsAsDistance2

void setMsAsDistance2(IPoint origin,
                      double scale,
                      double offset,

                             AutomationException

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:
origin - A reference to a com.esri.arcgis.geometry.IPoint (in)
scale - The scale (in)
offset - The offset (in)
ignoreGaps - The ignoreGaps (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

updateMsByDistance

void updateMsByDistance(int fromPart,
                        int fromPoint,
                        int toPart,
                        int toPoint,
                        double fromM,
                        double toM,
                        int updateHow,
                        boolean ignoreGaps)
                        throws IOException,
                               AutomationException
Updates Ms along the shortest path between the specified endpoints. The interpolation ratio is determined by the input ms and euclidean distance along that path. The update method is given as a combination of esriGeometryUpdateMEnum values.

Remarks

The updateHow argument is given as a combination of esriGeometryUpdateMEnum values. When combining multiple values, the bitwise Or operator should always be used. This assures an error-free combination of the values (as long as the attempted combination is valid). Do not use the addition operator (+) to combine the values as unexpected results may occur.

For example, to interpolate between the input points and to extrapolate before and after the input points, you would use 7, which equates to: esriGeometryInterpolate OR esriGeometryExtrapolateBefore OR esriGeometryExtrapolateAfter


esriGeometryInterpolate = 0001 (1)

esriGeometryExtrapolateBefore = 0010 (2)

esriGeometryExtrapolateAfter = 0100 (4)

calibrateByDistance

                                    int updateHow,
                                    boolean ignoreGaps,

                                    throws IOException,
                                           AutomationException
Calibrates Ms of existing vertices using new Ms from the input points and the shortest path distances along the polyline between those points. The update method is given as a combination of esriGeometryUpdateMEnum values.

Remarks

The updateHow argument is given as a combination of esriGeometryUpdateMEnum values. When combining multiple values, the bitwise Or operator should always be used. This assures an error-free combination of the values (as long as the attempted combination is valid). Do not use the addition operator (+) to combine the values as unexpected results may occur.

For example, to interpolate between the input points and to extrapolate before and after the input points, you would use 7, which equates to: esriGeometryInterpolate OR esriGeometryExtrapolateBefore OR esriGeometryExtrapolateAfter. A value of 0 will only split the input polyline and assign the Ms value to the new created vertex. If an input point has the same X (or projected to the same X) as an existing vertex the Ms value of the existing vertex will be updated.

Note : The "After" and "Before" for the updateHow parameter is define by the order of the points in the multipoints. Ex : If the points are define from left to right the "Before" will be at the left of the first point and the "After" will be at the right of the last point.

The cutoffDistance parameter is an input Double that represents the distance from the polyline from where points are not considered anymore as being valid calibration points.

The following picture demonstrates graphically the method behavior. A updateHow paramater of 7 has been used.

esriGeometryInterpolate = 0001 (1)
esriGeometryExtrapolateBefore = 0010 (2)
esriGeometryExtrapolateAfter = 0100 (4)
