All Implemented Interfaces:

Symbol<P>

public class SequenceOfSeparatedSymbols<P extends Processor>
extends AbstractSymbol<P>

Compound with two symbols where one symbol is a delimiter. The symbol can appears zero times or more. Between two successive symbols there has to be the delimiter.

Constructor Summary

SequenceOfSeparatedSymbols(Symbol<P> symbol, Symbol<P> delimiter)
Creates an instance for the specified symbol and delimiter.

Method Summary

protected void	doProcess(TokenIterator iterator, P processor) Processes the wrapped symbol if it matches otherwise does nothing.
MatchingResult	matches(Token token) Returns MatchingResult.OK.

Constructor Detail

SequenceOfSeparatedSymbols

public SequenceOfSeparatedSymbols(Symbol<P> symbol,
                                  Symbol<P> delimiter)

Creates an instance for the specified symbol and delimiter.

Method Detail

matches

public MatchingResult matches(Token token)

Returns MatchingResult.OK.

Parameters:

token - Token to be checked. Will be null if beyond last token.

doProcess

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

Processes the wrapped symbol if it matches otherwise does nothing. Next the delimiter and the symbol are processed if the delimiter matches. This step is repeated as long as the delimiter matches.

Specified by:

doProcess in class AbstractSymbol<P extends Processor>

processor - Processor who does the actual processing.

Throws:

ParsingException - if a parsing error occurs.
