Class WCService_Impl

java.lang.Object
  org.deegree_impl.services.OGCWebService_Impl
      org.deegree_impl.services.wcs.WCService_Impl

All Implemented Interfaces:

java.util.EventListener, Handler, OGCWebService

public class WCService_Impl

extends OGCWebService_Impl

implements Handler

This is the basic implementation for a OGC conform web coverage service within the deegree framework. A WCSService extends the OGCWebService interface to act like a OGC web service. This means that a WCS is callable through the doService-method inherited from OGCWebService.

Constructor Summary

WCService_Impl(CVDescriptor[] descriptors)
Creates a new WCService_Impl object.

WCService_Impl(WCSCapabilities capabilities)
Creates a new WCService_Impl object.

Method Summary

java.lang.Object	clone() returns a copy of the WCService_Impl using the same capabilities reference
private WCSGetCoverageResponse	createErrorResponse(OGCWebServiceRequest request, java.lang.Exception ex, java.lang.String location) returns a response object that contains an error message
void	doService(OGCWebServiceEvent event) the implementation of this method performs the handling of the passed OGCWebServiceEvent in an new own Thread.
OGCWebServiceResponse	doService(OGCWebServiceRequest request) the method performs the handling of the passed OGCWebServiceEvent directly and returns the result to the calling class/method
private java.lang.Object	getSerializedImage(java.lang.Object image, java.lang.String format) serializes the submitted image to a byte array. the format of the serialization depends on the also submitted format. at the moment gif, jpeg, tiff, png and bmp are supported.
private WCSGetCoverageResponse	handleGetCoverageRequest(OGCWebServiceEvent event) handles a GetCoverage request
void	handleRequest(OGCWebServiceEvent event) handles a request against an OGC web service
void	handleResponse(OGCWebServiceEvent response) handles the response of an OGC web service
boolean	isInterested(OGCWebServiceEvent event) returns true if the handler is interested in a event
void	registerHandler(Handler handler) registers a Handler so this Handler is able to act as a proxy to the registered handler

Method Detail

clone

public java.lang.Object clone()

returns a copy of the WCService_Impl using the same capabilities reference

Returns:

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

doService

public OGCWebServiceResponse doService(OGCWebServiceRequest request)
                                throws WebServiceException

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

handleRequest

public void handleRequest(OGCWebServiceEvent event)

handles a request against an OGC web service

Specified by:

handleRequest in interface Handler

handleGetCoverageRequest

private WCSGetCoverageResponse handleGetCoverageRequest(OGCWebServiceEvent event)

handles a GetCoverage request

createErrorResponse

private WCSGetCoverageResponse createErrorResponse(OGCWebServiceRequest request,
                                                   java.lang.Exception ex,
                                                   java.lang.String location)

returns a response object that contains an error message

getSerializedImage

private java.lang.Object getSerializedImage(java.lang.Object image,
                                            java.lang.String format)
                                     throws NotSupportedFormatException,

Throws:

NotSupportedFormatException

java.lang.Exception

handleResponse

public void handleResponse(OGCWebServiceEvent response)

handles the response of an OGC web service

Specified by:

handleResponse in interface Handler

isInterested

public boolean isInterested(OGCWebServiceEvent event)

returns true if the handler is interested in a event

Specified by:

isInterested in interface Handler

registerHandler
