public class AuthorizableQueryManager extends Object
This class handles the translation of queries for users and groups from a JSON format to the query model of Jackrabbit's user groups search (see UserManager#findAuthorizables(Query)). The JSON query format is defined as follows: 
{
  ( selector: "authorizable" | "user" | "group" )?        // Defaults to "authorizable", see QueryBuilder#setSelector()

  (
    scope:                                                // See QueryBuilder#setScope()
    {
      groupName: /* group name (String) * /
      ( declaredOnly: true | false )                      // Defaults to true
    }
  ) ?                                                     // Defaults to all

  ( condition: [ CONJUNCTION+ ] ) ?                       // Defaults to a 'true' condition, see QueryBuilder#setCondition()

  (
    order | sort:                                         // See QueryBuilder#setOrder()
    {
      property: /* relative path (String) * /
      ( direction: "asc" | "desc" )                       // Defaults to "asc"
      ( ignoreCase: true | false )                        // Defaults to "true", see QueryBuilder#setSortOrder()
    }
  ) ?                                                     // Defaults to document order

  (
    limit:                                                // See QueryBuilder#setLimit()
    {
      offset: /* Positive Integer * /                     // Takes precedence over bound if both are given
      bound:  /* String, Number, Boolean * /
      max:    /* Positive Integer or -1 * /               // Defaults to no limit (-1)
    }
  ) ?                                                     // Defaults to all
}

  • A relative path refers to a property or a child node of an user or a group. Property names need to be prefixed with the at (@) character. Invalid JCR characters need proper escaping. The current path is denoted by a dot (.).
  • In a 'pattern' the percent character (%) represents any string of zero or more characters and the underscore character (_) represents any single character. Any literal use of these characters and the backslash character (\) must be escaped with a backslash character. The pattern is matched against Authorizable#getID() and Authorizable#getPrincipal().
  • The syntax of 'expression' is [-]value { [OR] [-]value }.
