Attributes: eof_index - index of EOF, or -1 timeout_index - index of TIMEOUT, or -1 After a successful match by the search() method the following attributes are available: start - index into the buffer, first byte of match end - index into the buffer, first byte after match match - the matching string itself c C s\ d| _ d| _g | _xDt|�D ]8\}}|tkr4|| _ q |tkrD|| _q | jj||f� q W dS )z�This creates an instance of searcher_string.

'freshlen' must indicate the number of bytes at the end of 'buffer' which have not been searched before. It helps to avoid searching the same, possibly big, buffer over and over again. See class spawn for the 'searchwindowsize' argument. If there is a match this returns the index of that string, and sets 'start', 'end' and 'match'. Otherwise, this returns -1.
