      • addAttribute

        public void addAttribute​(java.lang.String key,
                                 java.lang.String nsPrefix,

      • addPCData

        public void addPCData​(java.io.Reader reader,
                              java.lang.String systemID,
                              int lineNr)
        This method is called when a PCDATA element is encountered. A Java reader is supplied from which you can read the data. The reader will only read the data of the element. You don't need to check for boundaries. If you don't read the full element, the rest of the data is skipped. You also don't have to care about entities; they are resolved by the parser.
        Specified by:
        addPCData in interface IXMLBuilder
        Parameters:
        reader - the Java reader from which you can retrieve the data.
        systemID - the system ID of the XML data source.
        lineNr - the line in the source where the element starts.
      • getResult

        public java.lang.Object getResult()
        Returns the result of the building process. This method is called just before the parse method of IXMLParser returns.
        Specified by:
        getResult in interface IXMLBuilder
        Returns:
        the result of the building process.
