Members

		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.
	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.
	ExtrapolateMs	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.
	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.
	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.
	GetSubcurveBetweenMs	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.
	InsertMAtDistance	Sets the M value at the given 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].
	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.
	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.
	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.
