Method Detail

getSpatialAttribute

public JGeometry getSpatialAttribute()

Returns the spatial attribute object.

Overrides:

getSpatialAttribute in class AbstractFeature

Returns:

setSpatialAttribute

public void setSpatialAttribute(java.lang.Object spatialAttr)

Sets the spatial attribute object

Overrides:

setSpatialAttribute in class AbstractFeature

Parameters:

spatialAttr -

getMBR

public java.awt.geom.Rectangle2D getMBR()

Returns the minimum bounding rectangle of the spatial attribute.

Specified by:

getMBR in interface GeoObject

Specified by:

getMBR in class AbstractFeature

Returns:

getSpatialDimension

public int getSpatialDimension()

Returns the feature spatial dimension.

Specified by:

getSpatialDimension in class AbstractFeature

Returns:

-1 if geometry is null.

getSpatialAttributeClone

public JGeometry getSpatialAttributeClone()

Returns a clone of the spatial attribute

Specified by:

getSpatialAttributeClone in class AbstractFeature

Returns:

getSpatialJavaPoints

public java.awt.geom.Point2D[] getSpatialJavaPoints()

Returns an array of java points representing the vertexes location of the spatial object.

Specified by:

getSpatialJavaPoints in class AbstractFeature

Returns:

getDrawable

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

Description copied from interface: GeoObject

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.

Returns:

a Drawable instance that references either a Shape or a Point2D

isSubElementOf

public boolean isSubElementOf(GeoObject obj)

Description copied from interface: GeoObject

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

Returns:
