com.stuffwithstuff.bantam.parselets.InfixParselet
One of the two parselet interfaces used by the Pratt parser. An InfixParselet is associated with a token that appears in the middle of the expression it parses. Its parse() method will be called after the left-hand side has been parsed, and it in turn is responsible for parsing everything that comes after the token. This is also used for postfix expressions, in which case it simply doesn't consume any more tokens in its parse() call.

    Expression left = prefix.parse(this, token);
    
    while (precedence < getPrecedence()) {
      token = consume();
      
      InfixParselet infix = mInfixParselets.get(token.getType());
      left = infix.parse(this, left, token);
    }
    
    return left;
  }

    // Get the queued token.

  private int getPrecedence() {

    if (parser != null) return parser.getPrecedence();
    
    return 0;
