Constructor Detail

DefaultGeometryType

public DefaultGeometryType(Class geomClass,
                           String name,
                           int id,
                           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 id,
                           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.

Specified by:

create in interface GeometryType

Returns:

A new geometry

Throws:

CreateGeometryException

setGeometryOperation

public void setGeometryOperation(int index,
                                 GeometryOperation geomOp)

Guardamos una referencia a una instancia de la operación en el índice que se pasa como parámetro. Si el índice ya está ocupado se sobrescribe.

Specified by:

setGeometryOperation in interface GeometryType

Parameters:

index -

geomOp -

getGeometryOperation

public GeometryOperation getGeometryOperation(int index)

Description copied from interface: GeometryType

Get the operation for this geometry at a concrete position

Specified by:

getGeometryOperation in interface GeometryType

Parameters:

index - The position of the operation

Returns:

A geometry operation

getGeometryClass

public Class getGeometryClass()

toString

public String toString()

Specified by:

toString in interface GeometryType

Overrides:

toString in class Object

Returns:

the geometry as a String

getId

public int getId()

Specified by:

getId in interface GeometryType

Returns:

the identifier of the geometry type. This identifier is assigned by the GeometryManager in run time.

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

isTypeOf

public boolean isTypeOf(GeometryType 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 geometry type to check if is it super type

Returns:

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

isSubTypeOf

public boolean isSubTypeOf(GeometryType geometryType)

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:

geometryType - the geometry type to check if is it super subtype

Returns:

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

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
