Method Detail

clone

public ImageObject clone()

Overrides:

clone in class java.lang.Object

isSubElementOf

public boolean isSubElementOf(GeoObject obj)

Description copied from interface: GeoObject

Returns true if this GeoObject is a sub element of the provided GeoObject

Specified by:

isSubElementOf in interface GeoObject

Returns:

substract

public java.util.List<GeoObject> substract(java.util.List<? extends GeoObject> obj)

Description copied from interface: GeoObject

Returns a set of GeoObjects that represent the substraction of the provided GeoObjects from this GeoObject

Specified by:

substract in interface GeoObject

Returns:

getKey

public java.lang.Object getKey()

Gets the key of the selected object.

Specified by:

getKey in interface GeoObject

Returns:

the key

setKey

public java.lang.Object setKey(java.lang.Object key)

Sets a new key on the object.

Specified by:

setKey in interface GeoObject

Parameters:

key - the new key to be set.

Returns:

previously set key

getLayer

public Layer getLayer()

Gets the associated layer for this object.

Specified by:

getLayer in interface GeoObject

Returns:

the Layer instance that owns this object.

setLayer

public void setLayer(Layer layer)

Sets the layer to be associated with this object.

Specified by:

setLayer in interface GeoObject

Parameters:

layer - the layer to be associated.

getImage

public java.awt.Image getImage()

Gets the image associated with this geo-object.

Returns:

getDrawable

public Drawable getDrawable(java.awt.geom.AffineTransform viewportTransform)

This method returns a drawable Java2D shape or point that can be directly rendered onto a device. If a non-null viewportTransform is supplied, then it is applied and result returned.

Specified by:

getDrawable in interface GeoObject

Parameters:

viewportTransform -

Returns:

a Drawable instance that references either a Shape or a Point2D

getDrawables

public Drawable[] getDrawables(java.awt.geom.AffineTransform viewportTransform)

This method returns an array of drawable Java2D shape or point that can be directly rendered onto a device. If a non-null viewportTransform is supplied, then it is applied and result returned. This can be used to get pieces of geometry collections or multi points.

Parameters:

viewportTransform -

Returns:

a Drawable instance that references either a Shape or a Point2D

getMBR

public java.awt.geom.Rectangle2D getMBR()

Description copied from interface: GeoObject

Gets the minimum bounding rectangle of this geo-object. The rectangle is in the same coordinate system as the object value.

Specified by:

getMBR in interface GeoObject
