NAME

6       Test2::Compare::Negatable - Poor mans 'role' for compare objects that
7       can be negated.
8

DESCRIPTION

10       Using this package inside an Test2::Compare::Base subclass will
11       overload "!$obj" and import "clone_negate()" and "toggle_negate()".
12

WHY?

14       Until perl 5.18 the 'fallback' parameter to overload would not be
15       inherited, so we cannot use inheritance for the behavior we actually
16       want. This module works around the problem by emulating the "use
17       overload" call we want for each consumer class.
18

ATTRIBUTES

20       $bool = $obj->negate
21       $obj->set_negate($bool)
22       $attr = NEGATE()
23           The NEGATE attribute will be added via Test2::Util::HashBase.
24

METHODS

26       $clone = $obj->clone_negate()
27           Create a shallow copy of the object, and call "toggle_negate" on
28           it.
29
30       $obj->toggle_negate()
31           Toggle the negate attribute. If the attribute was on it will now be
32           off, if it was off it will now be on.
