    • startTokenization

      void startTokenization(Tokenizer self) throws SAXException
      This method is called at the start of tokenization before any other methods on this interface are called. Implementations should hold the reference to the Tokenizer in order to set the content model flag and in order to be able to query for Locator data.
      Parameters:
      self - the Tokenizer.
      Throws:
      SAXException - if something went wrong
    • wantsComments

      boolean wantsComments() throws SAXException
      If this handler implementation cares about comments, return true. If not, return false.
      Returns:
      whether this handler wants comments
      Throws:
      SAXException - if something went wrong
    • doctype

      void doctype(String name, String publicIdentifier, String systemIdentifier, boolean forceQuirks) throws SAXException
      Receive a doctype token.
      Parameters:
      name - the name
      publicIdentifier - the public id
      systemIdentifier - the system id
      forceQuirks - whether the token is correct
      Throws:
      SAXException - if something went wrong
    • startTag

      void startTag(ElementName eltName, HtmlAttributes attributes, boolean selfClosing) throws SAXException
      Receive a start tag token.
      Parameters:
      eltName - the tag name
      attributes - the attributes
      selfClosing - TODO
      Throws:
      SAXException - if something went wrong
    • endTag

      void endTag(ElementName eltName) throws SAXException
      Receive an end tag token.
      Parameters:
      eltName - the tag name
      Throws:
      SAXException - if something went wrong
    • comment

      void comment(char[] buf, int start, int length) throws SAXException

      Parameters:
      buf - a buffer holding the data
      start - the offset into the buffer
      length - the number of code units to read
      Throws:
      SAXException - if something went wrong
    • characters

      void characters(char[] buf, int start, int length) throws SAXException
      Receive character tokens. This method has the same semantics as the SAX method of the same name.
