Constructor Detail

DefaultGeometryType

public DefaultGeometryType(Class geomClass,
                           String name,
                           int type,
                           int subType,
                           int[] superTypes,
                           int[] superSubTypes)

This constructor is used by the GeometryManager when it register a new GeometryType. It has not be used from other parts.

Parameters:

geomClass - Geometry class (e.g: Point2D.class)

name - Symbolic Geometry name that is used to persist the geometry type. In some cases, it is better to use this name because the id can change for different application executions.

id - Geometry id

typeName - The geometry type name

type - The geometry abstract type

superTypes - The superTypes of the geometry type

superSubTypes - The superSubtypes of the geometry type

DefaultGeometryType

public DefaultGeometryType(Class geomClass,
                           String name,
                           int type,
                           int subType)

This constructor is used by the GeometryManager when it register a new GeometryType. It has not be used from other parts.

Parameters:

geomClass - Geometry class (e.g: Point2D.class)

name - Symbolic Geometry name that is used to persist the geometry type. In some cases, it is better to use this name because the id can change for different application executions.

id - Geometry id

typeName - The geometry type name

type - The geometry abstract type

Method Detail

create

public Geometry create()
                throws CreateGeometryException

This method creates a Geometry with the type specified by this GeometryType. The geometry has to have a constructor without arguments.

Returns:

A new geometry

Throws:

CreateGeometryException

getGeometryClass

public Class getGeometryClass()

getName

public String getName()

Returns:

the name of the geometry type.

getType

public int getType()

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()

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...

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.

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
