Method Detail

doService

public void doService(OGCWebServiceEvent event)
               throws WebServiceException

Description copied from interface: OGCWebService

the implementation of this method performs the handling of the passed OGCWebServiceEvent in an new own Thread. The receiver of the response to the request must implement the OGCWebServiceClient interface

Specified by:

doService in interface OGCWebService

Parameters:

event -

Throws:

WebServiceException

getBoxes

GM_Surface[][] getBoxes()

returns the boxes the requested area has been splitted up to

setDEMTile

void setDEMTile(java.lang.Object tile,
                int x,
                int y)

the method performs the handling of the passed OGCWebServiceEvent directly and returns the result to the calling class/method

Specified by:

doService in interface OGCWebService

Parameters:

request - request (WMS, WCS, WFS, WCAS, WCTS, WTS, Gazetter) to perform

Throws:

WebServiceException

handleGetCapabilities

private void handleGetCapabilities(WTSGetCapabilitiesRequest request)

performs a get capabilities request by writing an XML representation of the capabilities to the receiver (destination) of the response of the request.

handleGetView

private void handleGetView(WTSGetViewRequest request)
                    throws java.lang.Exception

performs a get view request by initializing a WTSScene, forcing an offscreen rendering of the scene and writing the resulting image encapsulated into a GetViewResponse object to the receiver of the response.

Throws:

java.lang.Exception

createViewPoint

private static ViewPoint createViewPoint(WTSGetViewRequest request)

creates a ViewPoint from a WTSGetViewRequest

write

public void write(java.lang.Object result)

receives the results from the service calls and fills the texture and tiles matrices

Specified by:

write in interface OGCWebServiceClient

Parameters:

result - result of a service call

handleException

protected void handleException(java.lang.String error)
