    • isClassTraceOn

      public static boolean isClassTraceOn()
      Deprecated.
      This method has been deprecated. It is recommended to use the standard Java logging framework directly.
      Returns true if tracing is enabled for this class.
      Returns:
      true if tracing is enabled for this class, false otherwise.

    • setClassTraceOn

      public static void setClassTraceOn(boolean aClassTraceOn)
      Deprecated.
      This method has been deprecated. It is recommended to use the standard Java logging framework directly.
      Enables tracing for all instances of this class. If the argument is true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.
      Parameters:
      aClassTraceOn - if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

    • encodeGXYView

      public String encodeGXYView(ILcdGXYView aView, OutputStream aOutputStream, ALcdRequestContext aRequestContext) throws IOException
      Description copied from interface: ILcdGXYViewEncoder
      Encodes a given ILcdGXYView to the provided OutputStream.
      Specified by:
      encodeGXYView in interface ILcdGXYViewEncoder
      Parameters:
      aView - the ILcdGXYView to be encoded. You can rely on its getImage method to access the rendered view.
      aOutputStream - the OutputStream to write the encoded view to.
      aRequestContext - an ALcdRequestContext giving access to the request parameters. Can be null.
      Returns:
      the content type used by the encoding. This is set as content type on the HTTP(S) response and cannot be null.
      Throws:
      IOException - if an I/O exception occurs during the encoding

    • getContentType

      public String getContentType()
      Description copied from interface: ILcdGXYViewEncoder
      Returns a content type that identifies the encoding approach used by this encoder and that gets advertised in the OGC service capabilities. This is usually the MIME type of the encoded result, but this is not required: it is up to the encodeGXYView method to return the actually used content type for a given ILcdGXYView.
      Specified by:
      getContentType in interface ILcdGXYViewEncoder
      Specified by:
      getContentType in interface ILcdWMSFeatureInfoRequestEncoder
      Returns:
      the content type that identifies the encoding approach used by this encoder

    • encode

      public void encode(ILcdGXYLayerSubsetList aSelectionSublist, OutputStream aOutputStream, ILcdGXYView aGXYView) throws jakarta.servlet.ServletException
      Encodes the ILcdGXYView to a JPEG and writes in to the given OutputStrean. The elements of the given TLcdGXYLayerSubsetList are painted in the ILcdGXYView in the selection color.
      Specified by:
      encode in interface ILcdWMSFeatureInfoRequestEncoder
      Parameters:
      aSelectionSublist - a TLcdGXYLayerSubsetList containing the selection to be encoded.
      aOutputStream - the OutputStream to write the output to.
      aGXYView - the ILcdGXYView in which the elements are selected .
      Throws:
      jakarta.servlet.ServletException - for writing and sending exceptions.
