Class ShapeType

Object
  ShapeType

public final class ShapeType
extends Object

Not much but a type safe enumeration of file types as ints and names. The descriptions can easily be tied to a ResourceBundle if someone wants to do that.

Constructor Detail

ShapeType

protected ShapeType(int id,
                    String name)

Creates a new instance of ShapeType. Hidden on purpose.

Parameters:

id - The id.

name - The name.

Method Detail

toString

public String toString()

Get the name of this ShapeType.

Overrides:

toString in class Object

Returns:

The name.

isMultiPoint

public boolean isMultiPoint()

Is this a multipoint shape? Hint- all shapes are multipoint except NULL, UNDEFINED, and the POINTs.

Returns:

true if multipoint, false otherwise.

isPointType

public boolean isPointType()

isLineType

public boolean isLineType()

isPolygonType

public boolean isPolygonType()

isMultiPointType

public boolean isMultiPointType()

forID

public static ShapeType forID(int id)

Determine the ShapeType for the id.

Parameters:

id - The id to search for.

Returns:

The ShapeType for the id.

getShapeHandler

public ShapeHandler getShapeHandler(GeometryFactory gf)
                             throws ShapefileException

Each ShapeType corresponds to a handler. In the future this should probably go else where to allow different handlers, or something...

Returns:

The correct handler for this ShapeType. Returns a new one.

Throws:

ShapefileException - If the ShapeType is bogus.
