Class SimplePrintListener

java.lang.Object
  org.deegree.enterprise.control.AbstractListener
      org.deegree.portal.common.control.AbstractSimplePrintListener
          org.deegree.portal.standard.wms.control.SimplePrintListener

All Implemented Interfaces:

EventListener, WebListener

public class SimplePrintListener
extends AbstractSimplePrintListener

This class prints the View context. It inherits from AbstractSimplePrintListner and implement the abstract method getViewContext TODO The methods changeBBox(), changeLayerList(), extractBBox() are already implemented in AbstractContextListner. The question now is wether to inherit from AbstractContextListner instead of AbstractListner?

public SimplePrintListener()

Method Detail

getViewContext

protected ViewContext getViewContext(RPCWebEvent rpc)

Description copied from class: AbstractSimplePrintListener

reads the view context to print from the users session

Specified by:

getViewContext in class AbstractSimplePrintListener

Returns:

the viewcontext defined by the rpc

extractBBox

protected Envelope extractBBox(RPCStruct bboxStruct,
                               CoordinateSystem crs)

Convenience method to extract the boundig box from an rpc fragment.

Parameters:

bboxStruct - the RPCStruct containing the bounding box. For example, <member><name>boundingBox</name>etc....

crs - a coordinate system value, may be null.

Returns:

an envelope with the boundaries defined in the rpc structure

changeLayerList

protected void changeLayerList(ViewContext vc,
                               RPCMember[] rpcLayerList)
                        throws PortalException

changes the layer list of the ViewContext vc according to the information contained in the rpcLayerList

Parameters:

vc - The original ViewContext where the changes will be applied to

rpcLayerList - the current layerlist

Throws:

PortalException

changeBBox

public static final void changeBBox(ViewContext vc,
                                    Envelope bbox)
                             throws PortalException

changes the bounding box of a given view context

Parameters:

vc - the view context to be changed

bbox - the new bounding box

Throws:

PortalException
