    Query object classes.

Parameter:
    policy          The policy to query.

Keyword Parameters/Class attributes:
    name            The name of the object set to match.
    name_regex      If true, regular expression matching will
                    be used for matching the name.
    common          The name of the inherited common to match.
    common_regex    If true, regular expression matching will
                    be used for matching the common name.
    perms           The permissions to match.
    perms_equal     If true, only commons with permission sets
                    that are equal to the criteria will
                    match.  Otherwise, any intersection
                    will match.
    perms_regex     If true, regular expression matching
                    will be used on the permission names instead
                    of set logic.
                    comparison will not be used.
    perms_indirect  If false, permissions inherited from a common
                    permission set not will be evaluated.  Default
                    is true.
