Interface ILineString

All Superinterfaces:

ICurveSegment, IGeometry, Serializable

public interface ILineString
extends ICurveSegment

An ILineString is an ICurveSegment where the control points are connected with straight lines (i.e., linear interpolation between the control points).

Method Summary

Modifier and Type	Method and Description
ILineString	asLineString() Returns an ILineString that approximates this ICurveSegment.
ILineString	asLineString(Length maxSpacing, Length maxOffset) Returns an ILineString that approximates this ICurveSegment.
ILineString	getCopy() Get a (permanent) copy of this IGeometry.
ILineString	getCopy(CoordSys crs) Get a (permanent) copy of this IGeometry transformed to the given coordinate system.
ILineString	reverse() Returns an ICurveSegment that has the opposite orientation as this ICurveSegment.

Method Detail

getCopy

ILineString getCopy()

Description copied from interface: IGeometry

Get a (permanent) copy of this IGeometry.

Specified by:

getCopy in interface ICurveSegment

Specified by:

getCopy in interface IGeometry

Returns:

permanent copy of this IGeometry.

IGeometry.getCopy(CoordSys), IGeometry.isTransient()

getCopy

ILineString getCopy(CoordSys crs)

Description copied from interface: IGeometry

Get a (permanent) copy of this IGeometry transformed to the given coordinate system.

Specified by:

getCopy in interface ICurveSegment

Specified by:

getCopy in interface IGeometry

Parameters:

crs - coordinate system of the returned copy

Returns:

copy of this IGeometry in the given coordinate system

IGeometry.isTransient()

reverse

ILineString reverse()

Description copied from interface: ICurveSegment

Returns an ICurveSegment that has the opposite orientation as this ICurveSegment.

Specified by:

reverse in interface ICurveSegment

Returns:

an ICurveSegment that has the opposite orientation as this ICurveSegment.

asLineString

ILineString asLineString()

Description copied from interface: ICurveSegment

Returns an ILineString that approximates this ICurveSegment.

Specified by:

asLineString in interface ICurveSegment

Returns:

an ILineString that approximates this ICurveSegment.

asLineString

ILineString asLineString(Length maxSpacing,
                         Length maxOffset)

Description copied from interface: ICurveSegment

Returns an ILineString that approximates this ICurveSegment.

Approximates the ICurveSegment as a single ILineString. The first position of the second and subsequent segments of this curve are omitted because they would be x/y equal to the end position of the previous segment.

Regardless of parameters, the control points of all the curve segments are always included (except the first position of all but the first segment, as explained above). If both parameters are zero, then only the control points are returned.

Specified by:

asLineString in interface ICurveSegment

Parameters:

maxSpacing - the maximum distance between points in the constructed ILineString. A maxSpacing of zero means "no limit".

maxOffset - the maximum deviation of the constructed ILineString from this curve. A maxOffset of zero means "no limit".

Returns:

an ILineString that approximates this ICurveSegment.
