scan

public long scan(char target,
        int start,
        int end,
        int count,
        boolean allowQuit)

Description copied from class: Buffer

Search in BUF for COUNT instances of the character TARGET between START and END. If COUNT is positive, search forwards; END must be >= START. If COUNT is negative, search backwards for the -COUNTth instance; END must be <= START. If COUNT is zero, do anything you please; run rogue, for all I care. If END is zero, use beginning or end of (FIXME: accessible part of) the buffer, as appropriate for the direction indicated by COUNT. If we find COUNT instances, SHORTAGE is zero, and return the position after the COUNTth match. Note that for reverse motion this is not the same as the usual convention for Emacs motion commands. If we don't find COUNT instances before reaching END, set SHORTAGE to the number of TARGETs left unfound, and return (shortage<<32|END).

Specified by:

scan in class Buffer

Returns:

(SHORTAGE<<32|POS)

Buffer.scan(char, int, int, int, boolean)
