Examples of org.apache.xmlgraphics.ps.dsc.DSCListener.processEvent()

org.apache.xmlgraphics.ps.dsc.DSCListener.processEvent()
Called for each DSC event. You can call methods on the DSC parser to skip comments, for example. But implementations need to be good citizens and take into account that multiple listeners can be active at the same time and that they might interfere with other listeners. When returning from the call, state information such as filters should be restored. @param event the DSC event @param parser the DSC parser @throws IOException if an I/O error occurs @throws DSCException if a DSC-specific error occurs

            beginDocument = (DSCCommentBeginDocument)gotoDSCComment(
                    parser, DSCConstants.BEGIN_DOCUMENT);
            assertEquals("test/resources/images/barcode.eps",
                    beginDocument.getResource().getName());
            DSCListener listener = new DefaultNestedDocumentHandler(null);
            listener.processEvent(beginDocument, parser);


            //And again (the barcode is generated twice)
            beginDocument = (DSCCommentBeginDocument)gotoDSCComment(
                    parser, DSCConstants.BEGIN_DOCUMENT);
            assertEquals("test/resources/images/barcode.eps",
