#NAME

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

#DESCRIPTION

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

#WHY?

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

#ATTRIBUTES

#$bool = $obj->negate

#$obj->set_negate($bool)

#$attr = NEGATE()

The NEGATE attribute will be added via Test2::Util::HashBase.

#METHODS

#$clone = $obj->clone_negate()

Create a shallow copy of the object, and call toggle_negate on it.

#$obj->toggle_negate()

Toggle the negate attribute. If the attribute was on it will now be off, if it was off it will now be on.
