Name Description
CalculateNonSimpleMs Redefines the non-simple Ms to be values obtained from interpolation of surrounding defined Ms, or extrapolation of Ms.
CalibrateByDistance 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.
CalibrateByDistance3D Calibrates Ms of existing vertices using new Ms from the input points and the shortest 3D path distances along the polyline between those points. The update method is given as a combination of esriGeometryUpdateMEnum values.
CalibrateByMs Calibrates Ms of existing vertices using new Ms from the input points and existing Ms along shortest paths between those points. The update method is given as a combination of esriGeometryUpdateMEnum values.
CalibrateByMs3D Calibrates Ms of existing vertices using new Ms from the input points and existing Ms along the shortest 3D paths between those points. The update method is given as a combination of esriGeometryUpdateMEnum values.
ExtrapolateMs Extrapolates the Ms at one or both ends of the geometry based on the M interval between the fromIndex and the toIndex.
ExtrapolateMs3D Extrapolates the Ms at one or both ends of the geometry based on the M interval between the fromIndex and the toIndex.
GetDistancesAtM Returns an array of distances along the polyline at which is located the specified M. If the geometry's M's are monotonic along the geometry then the array will only have one element.
GetDistancesAtM3D Returns an array of 3D distances along the polyline at which is located the specified M. If the geometry's M's are monotonic along the geometry then the array will only have one element.
GetMsAtDistance Returns M values at the distance along the geometry. An array of one or two Ms is returned. Two Ms can be returned if the given distance is exactly at the beginning or ending of a part.
GetMsAtDistance3D Returns M values at the 3D distance along the geometry. An array of one or two Ms is returned. Two Ms can be returned if the given distance is exactly at the beginning or ending of a part.
GetNormalsAtM Returns a geometry bag of line segments corresponding to the normal at the locations along the geometry where the specified M occurs.
GetPointsAtM Returns a multipoint geometry corresponding to the locations along the geometry where the specified M occurs.
GetPointsAtM3D Returns a multipoint geometry corresponding to the locations along the geometry where the specified M occurs.
GetSubcurveBetweenMs Returns a polyline geometry corresponding to the subcurve(s) between the fromM and the toM.
GetSubcurveBetweenMs3D Returns a polyline geometry corresponding to the subcurve(s) between the fromM and the toM.
GetSubcurveBetweenMsEx Returns a polyline geometry corresponding to the subcurve(s) between the fromM and the toM values. The 'details' arguments are composed of esriMCurveRelationEnum values.
GetSubcurveBetweenMsEx3D Returns a polyline geometry corresponding to the subcurve(s) between the fromM and the toM values. The 'details' arguments are composed of esriMCurveRelationEnum values.
InsertMAtDistance Sets the M value at the given distance along the geometry; creates a point at that distance if no point exists there.
InsertMAtDistance3D Sets the M value at the given 3D distance along the geometry; creates a point at that distance if no point exists there.
InterpolateMsBetween Generates Ms by linear interpolation of segment distances for all vertices in the range [start+1, end-1].
InterpolateMsBetween3D Generates Ms by linear interpolation of 3D distances for all vertices in the range [start+1, end-1].
MMax The maximum M value.
MMin The minimum M value.
MMonotonic A value indicating whether Ms are monotonic, and if so, whether they are ascending or descending.
MMonotonicity A combination of esriMonotinicityEnum values that describes all trends in M values over the length of the curve.
MultiplyMs Multiplies all the M values by a factor.
OffsetMs Offsets all the M values by an offset value.
OrientByMs Re-orients the curve to make Ms non-decreasing, if possible.
QueryFirstLastM Returns the first and last defined M value for the curve.
ReverseMsOrder Reverses the order of the Ms along the geometry.
SetAndInterpolateMsBetween Sets the Ms at the beginning and the end of the geometry and interpolates the M values between these values.
SetAndInterpolateMsBetween3D Sets the Ms at the beginning and the end of the geometry and interpolates the M values between these values based on an interpolation normalized to the 3D length of the shape.
SetMsAsDistance Sets the M values to the cumulative length from the origin of the geometry.
SetMsAsDistance2 Sets Ms on vertices as scaled and offset distances from the input origin as measured along the polyline. Shortest path distances from the origin are used. Optionally ignores distances between parts of the polyline.
SetMsAsDistance3D Sets the M values to the cumulative 3D length from the origin of the geometry.
UpdateAllMsByMs Sets Ms on vertices as scaled and offset M distances from the input origin as measured along the polyline based on the existing M's. Shortest path distances from the origin are used. Optionally ignores distances between parts of the polyline.
UpdateMsByDistance 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.
UpdateMsByMs Updates Ms along the shortest path between the specified endpoints. The interpolation ratio is determined by the existing ms along that path and the input ms. The update method is given as a combination of esriGeometryUpdateMEnum values.
