class Set

A set is a collection that contains no duplicate elements.

Great care must be exercised if mutable objects are used as set elements. The behavior of a set is not specified if the value of an object is changed in a manner that affects equals comparisons while the object is an element in the set.

Example usage:

``` php $foo = new \My\Foo(); $set = new Set(\My\Foo::class);

$set->add($foo); // returns TRUE, the element doesn't exist $set->add($foo); // returns FALSE, the element already exists

$bar = new \My\Foo(); $set->add($bar); // returns TRUE, $bar !== $foo ```

@template T @extends AbstractSet<T>
