Method Details

getInfoReportParameters

public abstract Map getInfoReportParameters(JMapClientInfoReport infoReport,
 Point wcPoint,
 K2DTransform t)

close

public void close()

Description copied from class: Layer

Frees all resources used by the layer.

Specified by:

close in class Layer

drawGrid

public void drawGrid(GraphicsRef gr,
 K2DTransform t)

Description copied from class: Layer

Draws the tile grid for the layer.

Specified by:

drawGrid in class Layer

Parameters:

gr -

t -

getExtent

public Rectangle getExtent()

Description copied from class: Layer

Returns the extent of the layer.

Specified by:

getExtent in interface ILayer

Specified by:

getExtent in interface IRasterLayer

Specified by:

getExtent in class Layer

Returns:

the extent of the layer

getParameters

public RasterParameters getParameters()

Specified by:

getParameters in interface IRasterLayer

setParameters

public void setParameters(RasterParameters parameters)

Specified by:

setParameters in interface IRasterLayer

fireDataRequestedEvent

protected void fireDataRequestedEvent(Rectangle bounds,
 int imageWidth,
 int imageHeight,
 boolean sync)

setRawImage

protected abstract void setRawImage(byte[] rawImage,
 Rectangle bounds,
 boolean fireEvent)

clone

protected void clone(ILayer layer)

Description copied from class: Layer

Implementation of the clone method.

Overrides:

clone in class Layer

Parameters:

layer - the new layer instance.

setExtent

public void setExtent(Rectangle extent)

Specified by:

setExtent in interface IRasterLayer

getRequestMode

public int getRequestMode()

Description copied from class: Layer

Returns the request mode for this layer. The request mode can be either by tile (REQUEST_MODE_TILE) or by random region (REQUEST_MODE_REGION). When using requests by tile, predimensionned tiles are exchanged between JMapServer and the client application. When using requests by region, random regions of data are exchanged depending on the region the user is viewing. Requests by tiles are generally more performant because they allow caching on the server and client sides. Requests by region are useful when data must always be up-to-date, as it will be requested each time from the spatial data source.

Specified by:

getRequestMode in class Layer

Returns:

the current request mode in use by this layer.

getRasterTransformations

public RasterTransformationInfo[] getRasterTransformations()

setRasterTransformations

public void setRasterTransformations(RasterTransformationInfo[] transformations)

getRasterBands

public RasterBand[] getRasterBands()
