  • Field Details

  • Constructor Details

    • JccParser

      public JccParser(CharStream stream)
      Constructor with user supplied CharStream.

    • JccParser

      public JccParser(JccParserTokenManager tm)
      Constructor with generated Token Manager.

  • Method Details

    • parseStream

      public Node parseStream(CharStream stream, Jep jep, ArrayList<String> errorList) throws ParseException
      Throws:
      ParseException

    • restart

      public void restart(CharStream stream, Jep jep, ArrayList<String> errorList)
      Restart the parse with the given stream.
      Since:
      2.3.0 beta 1

    • continueParse

      public Node continueParse() throws ParseException
      Continue parsing without re-initializing the stream. Allows re-entrance of parser so that strings like "x=1; y=2; z=3;" can be parsed. When a semi colon is encountered parsing finishes leaving the rest of the string unparsed. Parsing can be resumed from the current position by using this method. For example 
       XJep j = new XJep();
 Parser parse = j.getParse();
 StringReader sr = new StringReader("x=1; y=2; z=3;");
 parse.restart(sr,j);
 Node node;
 try {
 while((node = j.continueParse())!=null) {
    j.println(node);
 } }catch(ParseException e) {}
      Empty expressions, such as the middle one in "x=1;;y=2" are returned as an ASTStart node, the end of file is returned as null.
      Throws:
      ParseException

    • setInitialTokenManagerState

      public void setInitialTokenManagerState(int state)
      Sets the initial state that the token manager is in. Can be used to change how x.x is interpreted, either as a single identifier (DEFAULT) or as x <DOT> x (NO_DOT_IN_IDENTIFIERS)
      Parameters:
      state - the state to be in. Currently the only legal values are DEFAULT and NO_DOT_IN_IDENTIFIER
