querySubcurve

                   throws IOException,
                          AutomationException

Copies a portion of this curve into an existing subcurve. AsRatio is true when fromDistance and toDistance are normalized to the interval [0..1].

Description

The QuerySubCurve method returns a polyline object corresponding to a portion of the input curve.

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).

subcurve: Output polyline object. It contains the output subcurve.

Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

querySubcurve in interface IEnumCurve2

Parameters:

fromDistance - The fromDistance (in)

toDistance - The toDistance (in)

asRatio - The asRatio (in)

subcurve - A reference to a com.esri.arcgis.geometry.ICurve (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryPoint

public void queryPoint(double fromDistance,
                       boolean asRatio,
                       IPoint pointOnCurve)
                throws IOException,
                       AutomationException

Copies a location on this curve into pointOnCurve. AsRatio is true when fromDistance is normalized to the interval [0..1].

Description

The QueryPoint method returns a point object located on the input curve at the fromDistance calculated along the curve. This method can be used to quickly retrieve a large sequence of evenly or unevenly spaced points along a curve. This could be used to place symbols along a curve, for example railroads.

Remarks

Note: Gaps between parts are ignored in distance computations.

Parameters description:

fromDistance: Input Double. Input distance that determines where along the point should be created. 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).

Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.
