Constructor Detail

LineStringImpl

protected LineStringImpl(Position[] gmps,
                         CoordinateSystem cs)
                  throws GeometryException

Creates a new LineStringImpl object.

Parameters:

gmps -

cs -

Throws:

GeometryException

Method Detail

clone

public Object clone()

Overrides:

clone in class CurveSegmentImpl

getLength

public double getLength()

Specified by:

getLength in interface GenericCurve

Returns:

length of the curve in units of the related spatial reference system

getAsLineString

public LineString getAsLineString()
                           throws GeometryException

returns a reference to itself

Specified by:

getAsLineString in interface GenericCurve

Returns:

the curve as LineString

Throws:

GeometryException

intersects

public boolean intersects(Geometry gmo)

The Boolean valued operation "intersects" shall return TRUE if this Geometry intersects another Geometry. Within a Complex, the Primitives do not intersect one another. In general, topologically structured data uses shared geometric objects to capture intersection information.

Specified by:

intersects in interface CurveSegment

Returns:

true if this geometry intersects with given geometry.

contains

public boolean contains(Geometry gmo)

Description copied from class: CurveSegmentImpl

The Boolean valued operation "contains" shall return TRUE if this Geometry contains another Geometry.

Specified by:

contains in interface CurveSegment

Overrides:

contains in class CurveSegmentImpl

Returns:

true if this geometry contains given geometry.
