Method Detail

createEmpty

public static Point createEmpty()

getPoints

public PointSequence getPoints()

Description copied from class: Geometry

Returns the PointCollection that is associated with this instance

Specified by:

getPoints in class Geometry

Returns:

getX

public double getX()

Returns the X-coordinate of this Point.

If this Point is empty, it returns Double.NaN.

Returns:

the X-coordinate of this Point

getY

public double getY()

Returns the Y-coordinate of this Point.

If this Point is empty, it returns Double.NaN.

Returns:

the Y-coordinate of this Point

getZ

public double getZ()

Returns the Z-coordinate of this Point.

If this Point is empty, it returns Double.NaN.

Returns:

the Z-coordinate of this Point

getM

public double getM()

Returns the M-coordinate of this Point.

If this Point is empty, it returns Double.NaN.

Returns:

the M-coordinate of this Point

getDimension

public int getDimension()

Description copied from class: Geometry

Returns the topological dimension of this instance. In non-homogenous collections, this will return the largest topological dimension of the contained Geometries.

Specified by:

getDimension in class Geometry

Returns:

getGeometryType

public GeometryType getGeometryType()

Description copied from class: Geometry

Returns the type of this Geometry.

Specified by:

getGeometryType in class Geometry

Returns:

the GeometryType of this instance.

isSimple

public boolean isSimple()

Description copied from class: Geometry

Tests if this Geometry is simple; i.e. has no anomalous geometric points such as self-intersections or self-tangency.

Overrides:

isSimple in class Geometry

Returns:

getBoundary

public Geometry getBoundary()

Description copied from class: Geometry

Returns the boundary of this Geometry.

Overrides:

getBoundary in class Geometry

Returns:

accept

public void accept(GeometryVisitor visitor)

Description copied from class: Geometry

Accepts a GeometryVisitor.

If this Geometry instance is a GeometryCollection then it will pass the visitor to its contained Geometries.

Specified by:

accept in class Geometry
