Modifier and Type	Method and Description
LinearRing	clone() Clones this geometry.
short	getGeometryId() Returns the geometry class id.
boolean	isRing() always true
boolean	isValid() Tests if the ring is valid.
void	setCoords(Point[] coords)
boolean	spatiallyEquals(Geometry o, PrecisionModel precisionModel) Tests if this geometry is equal to the argument, on a topological point of view.
boolean	spatiallyEquals(LinearRing ring) Deprecated.
boolean	spatiallyEquals(LinearRing ring, PrecisionModel precisionModel) Tests if this geometry is equal to the argument, on a topological point of view it means that they represents the same geometry, even if it is described differently (orientation of the rings, order of the rings) it does not remove additional points on lineString (3 points aligned), one must use smoother.removeExtraPoints() before in order to achieve that.
java.lang.String	toString() Returns informations about the current geometry.

Method Detail

setCoords

public void setCoords(Point[] coords)

Overrides:

setCoords in class LineString

isRing

public boolean isRing()

always true

Specified by:

isRing in interface Curve

Overrides:

isRing in class LineString

Returns:

toString

public java.lang.String toString()

Description copied from interface: Geometry

Returns informations about the current geometry.

Specified by:

toString in interface Geometry

Overrides:

toString in class LineString

Returns:

informations about the current geometry.

clone

public LinearRing clone()

Clones this geometry.

Specified by:

clone in interface Curve

Specified by:

clone in interface Geometry

Overrides:

clone in class LineString

Returns:

a deep copy of the current geometry.

spatiallyEquals

public boolean spatiallyEquals(Geometry o,
                               PrecisionModel precisionModel)

Description copied from class: LineString

Tests if this geometry is equal to the argument, on a topological point of view.

Specified by:

spatiallyEquals in interface Geometry

Overrides:

spatiallyEquals in class LineString

Parameters:

o - the geometry to be tested.

precisionModel - the precision model to use while comparing geometries.

Returns:

whether or not both geometries are spatially equals.

spatiallyEquals

@Deprecated
public boolean spatiallyEquals(LinearRing ring)

Deprecated.

Tests if this geometry is equal to the argument, on a topological point of view
it means that they represents the same geometry, even if it is described differently (orientation of the rings, order of the rings)
it does not remove additional points on lineString (3 points aligned), one must use smoother.removeExtraPoints() before in order to achieve that. here we first try to find a common point, then test equality in both orientation,

Parameters:

ring -

spatiallyEquals

public boolean spatiallyEquals(LinearRing ring,
                               PrecisionModel precisionModel)

Tests if this geometry is equal to the argument, on a topological point of view
it means that they represents the same geometry, even if it is described differently (orientation of the rings, order of the rings)
it does not remove additional points on lineString (3 points aligned), one must use smoother.removeExtraPoints() before in order to achieve that. here we first try to find a common point, then test equality in both orientation,

Parameters:

ring -

getGeometryId

public short getGeometryId()

Description copied from class: LineString

Returns the geometry class id. This method is useful for geometry serialization.

Specified by:

getGeometryId in interface Geometry

Overrides:

getGeometryId in class LineString

Returns:

the geometry id.

isValid

public boolean isValid()

Tests if the ring is valid. To be valid : Must have 0 or at least 3 coordinates, and first and last coordinate must be equal.

Returns:

true if valid
