doProcess

protected final void doProcess(TokenIterator iterator,
                               P processor)
                        throws ParsingException

Processes the current token of the specified iterator by invoking process(Token, Processor) and go to the next token.

Specified by:

doProcess in class AbstractSymbol<P extends Processor>

processor - Processor who does the actual processing.

Throws:

ParsingException - if a parsing error occurs.

process

protected void process(Token token,
                       P processor)
