java.lang.Object
  org.deegree_impl.graphics.Layer_Impl
      org.deegree_impl.graphics.RasterLayer_Impl

All Implemented Interfaces:

Layer, RasterLayer

class RasterLayer_Impl

extends Layer_Impl

implements RasterLayer

A RasterLayer represent a layer which data are contained within one single Image. The image/raster is geo-referenced by a GM_Envelope that is linked to it.

Constructor Detail

RasterLayer_Impl

RasterLayer_Impl(java.lang.String name,
                 GC_GridCoverage raster)
           throws java.lang.Exception

Creates a new Layer_Impl object.

Parameters:

name -

raster -

Throws:

java.lang.Exception

Method Detail

setCoordinatesSystem

public void setCoordinatesSystem(CS_CoordinateSystem crs)
                          throws java.lang.Exception

sets the coordinate reference system of the MapView. If a new crs is set all geometries of GeometryFeatures will be transformed to the new coordinate reference system.

Specified by:

setCoordinatesSystem in interface Layer

Throws:

java.lang.Exception

getRaster

public GC_GridCoverage getRaster()

returns the image/raster that represents the layers data

Specified by:

getRaster in interface RasterLayer

setRaster

public void setRaster(GC_GridCoverage raster)
               throws java.lang.Exception

sets the image/raster that represents the layers data

Specified by:

setRaster in interface RasterLayer

Throws:

java.lang.Exception

getName

public java.lang.String getName()

returns the name of the layer

Specified by:

getName in interface Layer

getBoundingBox

public GM_Envelope getBoundingBox()

returns the BoundingBox (Envelope) of Layer. This is the BoundingBox of the layers data. The BoundingBox of the View maybe larger or smaler

Specified by:

getBoundingBox in interface Layer

getCoordinatesSystem

public CS_CoordinateSystem getCoordinatesSystem()

returns the coordinate reference system of the MapView

Specified by:

getCoordinatesSystem in interface Layer

addEventController

public void addEventController(LayerEventController obj)

adds an eventcontroller to the MapView that's reponsible for handling events that targets the map. E.g.: zooming, panning, selecting a feature etc.

Specified by:

addEventController in interface Layer

removeEventController

public void removeEventController(LayerEventController obj)

Specified by:

removeEventController in interface Layer
