README
This package allows having "canonical objects".
Usage
Assuming "new Item(1)" will have id of "1":
$map = new IdentityMap(function ($item) { return $item->getId(); }); $item1 = new Item(1); $item2 = new Item(1); $item3 = new Item(2); echo $map->get($item1); // Will return item1 echo $map->get($item2); // Will return item1 echo $map->get($item3); // Will return item3
That way you can make sure items with the same key are the same physical objects
The closure argument that use pass to the identity map, needs to return the "unique key" for each product.
