Constructor Detail

Point2DGeometryType

public Point2DGeometryType()

Method Detail

getName

public String getName()

Specified by:

getName in interface GeometryType

Returns:

the name of the geometry type.

getType

public int getType()

Specified by:

getType in interface GeometryType

Returns:

the type of the geometry. It is a constant value that has to be one of the values in Geometry.TYPES The type is an abstract representation of the object (Point, Curve...) but it is not a concrete representation (Point2D, Point3D...).

getSubType

public int getSubType()

Specified by:

getSubType in interface GeometryType

Returns:

the subtype of the geometry. It is a constant value that has to be one of the values in Geometry.SUBTYPES. The subtype represents a set of geometries with a dimensional relationship (2D, 3D, 2DM...)

isTypeOf

public boolean isTypeOf(int geometryType)

Description copied from interface: GeometryType

Check if a geometry type inherits of other type. E.g: the super type of an arc could be a a curve, the super type of a circle could be a surface...

Specified by:

isTypeOf in interface GeometryType

Parameters:

geometryType - the value of the Geometry.TYPES to check if is it super type

Returns:

if the the parameter is a super type of this geometry type

isSubTypeOf

public boolean isSubTypeOf(int geometrySubType)

Description copied from interface: GeometryType

Check if a geometry subType inherits of other subType. E.g: the super Subtype of a geometry 3D could be a geometry 2D, because the 3D extends the behavior of a geometry 2D.

Specified by:

isSubTypeOf in interface GeometryType

Parameters:

geometrySubType - the value of the Geometry.SUBTYPES to check if is it super subType

Returns:

if the the parameter is a super subType of this geometry type

create

public Geometry create()
                throws CreateGeometryException

Description copied from interface: GeometryType

This method creates a Geometry with the type specified by this class. The geometry is empty, and all the internal attributes must be assigned to a value when the geometry has been created.

Specified by:

create in interface GeometryType

Returns:

A empty geometry

Throws:

CreateGeometryException

createPoint

public Point createPoint(double x,
                         double y)

Description copied from interface: PointGeometryType

Creates a new point object

Specified by:

createPoint in interface PointGeometryType

Parameters:

x - the x coordinate of the point

y - the y coordinate of the point

Returns:

the new point

createPoint

public Point createPoint(double[] coordinates)

Description copied from interface: PointGeometryType

Creates a new point object

Specified by:

createPoint in interface PointGeometryType

Parameters:

coordinates - the coordinates of the point

Returns:

the new point
