Constructor Details

#initialize(search_root, patterns, options = {}) ⇒ FileSearch

Initialises a FileSearch instance, which acts as an Enumerable of Recls::Entry

Signature

  • Parameters:

    • search_root (String, Recls::Entry) The root directory of the search. May be nil, in which case the current directory is assumed

    • patterns (String, Array) The pattern(s) for which to search. May be nil, in which case Recls::WILDCARDS_ALL is assumed

    • options (Hash, Integer) Combination of flags (with behaviour as described below for the flags option), or an options hash

  • Options:

    • flags (Integer) Combination of flags - FILES, DIRECTORIES, RECURSIVE, etc. If the value modulo TYPEMASK is 0, then FILES is assumed

Return

An instance of the class
