  - parse
```
Node parse(java.util.Iterator<Token> it)
    throws ParseException
```
    Main entry point used by the ConfigurableParser
    
    Parameters:
    
    it - iterator with the list of tokens
    
    Returns:
    
    the generated parser tree
    
    Throws:
    
    ParseException - if the input cannot be parsed
  - parseSubExpression
```
Node parseSubExpression()
                 throws ParseException
```
    Parse sub expressions. This methods is used by GrammarMatcher to parse sub expressions, for instance to parse function arguments.
    
    Returns:
    
    the root node of the matched sub expression.
    
    Throws:
    
    ParseException - if the input cannot be parsed
  - parsePrefixSuffix
```
Node parsePrefixSuffix()
                throws ParseException
```
    Callback function used by GrammerMatchers where the matcher expects a simple number, variable, or function call with optional, prefix or suffix operator.
    
    Returns:
    
    the root node of the matched sub expression.
    
    Throws:
    
    ParseException - if the input cannot be parsed

  - setIterator
```
void setIterator(Lookahead2Iterator<Token> it)
```
    Set the iterator used by the parseSubExpression()
    
    Parameters:
    
    it - the iterator
