Field Detail

### jjtree

    protected org.nfunk.jep.JJTParserState jjtree

### token_source

    public ParserTokenManager token_source

### token

    public Token token

### jj_nt

    public Token jj_nt

### lookingAhead

    public boolean lookingAhead

Constructor Detail

### Parser

    public Parser(java.io.InputStream stream)

### Parser

    public Parser(java.io.Reader stream)

### Parser

    public Parser(ParserTokenManager tm)

Method Detail

### parseStream

    public Node parseStream(java.io.Reader stream,
                            JEP jep_in)
                     throws ParseException

  Throws:
    `ParseException`

### restart

    public void restart(java.io.Reader stream,
                        JEP jep_in)

  Restart the parse with the given stream.

  Since:
    2.3.0 beta 1

### continueParse

    public Node continueParse()
                       throws ParseException

  Continue parsing without re-initilising stream. Allows renetrancy 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) {}

  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 x (NO_DOT_IN_IDENTIFIERS)

  Parameters:
    `state` - the state to be in. Currently the only legal values are DEFAULT and NO_DOT_IN_IDENTIFIER
