      • getKey

        public java.lang.Object getKey()
        Description copied from interface: GeoObject
        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)
        Description copied from interface: GeoObject
        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()
        Description copied from interface: GeoObject
        Gets the associated layer for this object.
        Specified by:
        getLayer in interface GeoObject
        Returns:
        typically an Layer instance that owns this object.

      • setLayer

        public void setLayer​(Layer layer)
        Description copied from interface: GeoObject
        Sets the layer to be associated with this object.

      • 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.
