Method Detail

clone

public MultiLineString clone()

Description copied from class: GeometryCollection

Clones this geometry.

Specified by:

clone in interface Geometry

Specified by:

clone in class GeometryCollection

Returns:

a deep copy of the current geometry.

serialize

public Point[] serialize()

Returns this geometry as an array of Point.

Specified by:

serialize in interface Geometry

Overrides:

serialize in class GeometryCollection

Returns:

this geometry as an array of Point.

isClosed

public boolean isClosed()

Specified by:

isClosed in interface LineTypeGeometry

Specified by:

isClosed in class MultiCurve

length

public double length()

Returns the geometry length. If the geometry is a surface, then the geometry perimeter shall be returned.

Specified by:

length in interface Geometry

Specified by:

length in class MultiCurve

Returns:

the geometry length.

setGeometries

public void setGeometries(Geometry[] geometries)

Specified by:

setGeometries in class GeometryCollection

getCurves

public LineString[] getCurves()

Returns:

setCurves

public void setCurves(LineString[] curves)

Parameters:

curves -

lineIterator

public LineGeometryIterator lineIterator()

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 java.lang.Object

Returns:

informations about the current geometry.

getGeometryId

public short getGeometryId()

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

Returns:

the geometry id.

getGeometryType

public int getGeometryType()

Returns the geometry type for this geometry.

Returns:

the geometry type.

See Also:

for more details.

getCenteredPoint

public Point getCenteredPoint()

This method returns a point that is typically centered on the geometry. If the geometry is a point, the point is returned. If it is a line, a point on the curve interpolated at 50% is returned. If the geometry is a surface, the centroid is returned if it is inside the polygon, if not, a point inside the polygon (but likely not exactly in the center) will be returned. If the geometry is a collection, the method is called on the first part of the collection.

Returns:

a point likely at the center of the geometry
