  31 // {{{ class UserFilter
  32 /** This class provides a convenient and centralized way of filtering users.
  33  *
  34  * Usage:
  35  * $uf = new UserFilter(new UFC_Blah($x, $y), new UFO_Coin($z, $t));
  36  *
  37  * Resulting UserFilter can be used to:
  38  * - get a list of User objects matching the filter
  39  * - get a list of UIDs matching the filter
  40  * - get the number of users matching the filter
  41  * - check whether a given User matches the filter
  42  * - filter a list of User objects depending on whether they match the filter
  43  *
  44  * Usage for UFC and UFO objects:
  45  * A UserFilter will call all private functions named XXXJoins.
  46  * These functions must return an array containing the list of join
  47  * required by the various UFC and UFO associated to the UserFilter.
  48  * Entries in those returned array are of the following form:
  49  *   'join_tablealias' => array('join_type', 'joined_table', 'join_criter')
  50  * which will be translated into :
  51  *   join_type JOIN joined_table AS join_tablealias ON (join_criter)
  52  * in the final query.
  53  *
  54  * In the join_criter text, $ME is replaced with 'join_tablealias', $PID with
  55  * profile.pid, and $UID with accounts.uid.
  56  *
  57  * For each kind of "JOIN" needed, a function named addXXXFilter() should be defined;
  58  * its parameter will be used to set various private vars of the UserFilter describing
  59  * the required joins ; such a function shall return the "join_tablealias" to use
  60  * when referring to the joined table.
  61  *
  62  * For example, if data from profile_job must be available to filter results,
  63  * the UFC object will call $uf-addJobFilter(), which will set the 'with_pj' var and
  64  * return 'pj', the short name to use when referring to profile_job; when building
  65  * the query, calling the jobJoins function will return an array containing a single
  66  * row:
  67  *   'pj' => array('left', 'profile_job', '$ME.pid = $UID');
  68  *
  69  * The 'register_optional' function can be used to generate unique table aliases when
  70  * the same table has to be joined several times with different aliases.
