    • setParseStatus

      public void setParseStatus(ParseStatus status)
      Description copied from interface: IMarkupHandler

      Sets the ParseStatus object that will be used during the parsing operation. This object can be used for instructing the parser about specific low-level conditions arisen during event handling.

      This method is always called by the parser before calling any other event handling method.

      Note that this method can be safely ignored by most implementations, as there are very few and very specific scenarios in which this kind of interaction with the parser would be needed. It is therefore mainly for internal use.

      Specified by:
      setParseStatus in interface IMarkupHandler
      Overrides:
      setParseStatus in class AbstractChainedMarkupHandler
      Parameters:
      status - the status object.
    • setParseConfiguration

      public void setParseConfiguration(ParseConfiguration parseConfiguration)
      Description copied from interface: IMarkupHandler

      Sets the ParseConfiguration object that will be used during the parsing operation. This object will normally have been specified to the parser object during its instantiation or initialization.

      This method is always called by the parser before calling any other event handling method.

      Note that this method can be safely ignored by most implementations, as there are very few scenarios in which this kind of interaction would be consisdered relevant.

      Specified by:
      setParseConfiguration in interface IMarkupHandler
      Overrides:
      setParseConfiguration in class AbstractChainedMarkupHandler
      Parameters:
      parseConfiguration - the configuration object.
    • handleDocumentEnd

      public void handleDocumentEnd(long endTimeNanos, long totalTimeNanos, int line, int col) throws ParseException
      Description copied from interface: IDocumentHandler

      Called at the end of document parsing.

      Specified by:
      handleDocumentEnd in interface IDocumentHandler
      Overrides:
      handleDocumentEnd in class AbstractChainedMarkupHandler
      Parameters:
      endTimeNanos - the current time (in nanoseconds) obtained when parsing ends.
      totalTimeNanos - the difference between current times at the start and end of parsing (in nanoseconds).
      line - the line of the document where parsing ends (usually the last one).
      col - the column of the document where the parsing ends (usually the last one).
      Throws:
      ParseException - if any exceptions occur during handling.
    • handleXmlDeclaration

      public void handleXmlDeclaration(char[] buffer, int keywordOffset, int keywordLen, int keywordLine, int keywordCol, int versionOffset, int versionLen, int versionLine, int versionCol, int encodingOffset, int encodingLen, int encodingLine, int encodingCol, int standaloneOffset, int standaloneLen, int standaloneLine, int standaloneCol, int outerOffset, int outerLen, int line, int col) throws ParseException
      Description copied from interface: IXMLDeclarationHandler

      Called when a XML Declaration is found.
