Enclosing class:

GetMapHandler_Impl

private class GetMapHandler_Impl.ServiceInvokerForNL

extends java.lang.Thread

implements OGCWebServiceClient

Inner class for accessing the data of one named layer and creating DisplayElements and a Thrme from it. The class extends Thread and implements the run method, so that a parallel data accessing from several layers is possible.

                                       int index)

Creates a new ServiceInvokerForNL object.

Parameters:

layer -

index - index of the requested layer

Method Detail

run

public void run()

overrides the run-method of the parent class Thread for enabling a multi-threaded access to the data.

Specified by:

run in interface java.lang.Runnable

createGetFeatureRequest

private OGCWebServiceEvent createGetFeatureRequest(DataSource ds)
                                            throws java.lang.Exception

Returns:

envent object containing a GetFeature request

Throws:

java.lang.Exception

createGetCoverageRequest

private OGCWebServiceEvent createGetCoverageRequest(DataSource ds)
                                             throws InconsistentRequestException

creates a getCoverage request considering the getMap request and the filterconditions defined in the submitted DataSource object The request will be encapsualted within a OGCWebServiceEvent.

Returns:

envent object containing a GetCoverage request

Throws:

InconsistentRequestException

createGetMapRequest

private OGCWebServiceEvent createGetMapRequest(DataSource ds)
                                        throws XMLParsingException

creates a getMap request for requesting a cascaded remote WMS considering the getMap request and the filterconditions defined in the submitted DataSource object The request will be encapsualted within a OGCWebServiceEvent.

Returns:

envent object containing a GetMap request

Throws:

XMLParsingException

write

public void write(java.lang.Object result)

The method implements the OGCWebServiceClient interface. So a deegree OWS implementation accessed by this class is able to return the result of a request by calling the write-method.

Specified by:

write in interface OGCWebServiceClient

Parameters:

result - to a GetXXX request

Throws:

java.lang.Exception

handleGetFeatureResponse

private void handleGetFeatureResponse(WFSGetFeatureResponse response)
                               throws java.lang.Exception

handles the response of a WFS and calls a factory to create DisplayElement and a Theme from it

Throws:

java.lang.Exception

handleGetCoverageResponse

private void handleGetCoverageResponse(WCSGetCoverageResponse response)
                                throws java.lang.Exception
