Public Methods
virtual bool	RegisterRegExp (unsigned int key, iRegExp &re)=0
	Register a regular expression for matching.
virtual bool	UnregisterRegExp (unsigned int key)=0
	Unregister a previously registered expression.
virtual unsigned int	GetFreeKey ()=0
	Requests a new (free) key.
virtual unsigned int	GetError ()=0
	Returns the last error. Value is only valid when a member function has returned false.
virtual unsigned int	GetMatchedKey ()=0
	Returns the key of the last RE matched.
virtual iString*	GetMatchedText ()=0
	Returns a pointer to the last matched text.
virtual bool	PushStream (iDataBuffer &buf)=0
	Saves the current input stream and state, then resets the current state and uses stream from buf.
virtual bool	PopStream ()=0
	Replaces the current input stream and state with the next stream and state on the stack.
virtual unsigned int	Match ()=0
	Scans the input stream for a match by one of the RegularExpression's returns 0 on failure, otherwise returns the key of the matched RE.
