Constructor Detail

FeatureInfoPortletPerform

public FeatureInfoPortletPerform(javax.servlet.http.HttpServletRequest request,
                                 org.apache.jetspeed.portal.Portlet portlet,
                                 javax.servlet.ServletContext sc)

Parameters:

request -

portlet -

sc - will be needed to evaluate the absolut path of the transform script(s)

Method Detail

init

public void init()

initializes the portlet by putting the init parameters to the users session. Even if this is not absolutly neccessary it simplifies a few things ...

doGetFeatureInfo

protected void doGetFeatureInfo()
                         throws PortalException,
                                OGCWebServiceException

performs a GetFeatureInfo/GetFeature/DescribeCoverage request depending on the layer typs the request targets. If defiend the result will be transformed by a XSLT script to get a human readable out put.

Throws:

PortalException

OGCWebServiceException

setCurrentFILayer

void setCurrentFILayer(String[] fiLayer)

sets the name of the the layers that are activated for feature info requests in the uses WMC

Parameters:

fiLayer -

perform

protected String perform(List<Layer> layerList,
                         ViewContext vc)
                  throws OGCWebServiceException,
                         PortalException

distributes the performance of the feature info requests depending on the requested service to a specialized method

Parameters:

layerList - list of context layers provided by the same OWS

vc -

Returns:

formated feature info result

Throws:

OGCWebServiceException

PortalException

findCurrentFILayers

String[] findCurrentFILayers()

sets the name of the the layers that are activated for feature info requests in the uses WMC

Returns:

layers involved in feature info
