The identity map pattern is a database access design pattern used to improve performance by providing a context-specific, in-memory cache to prevent duplicate retrieval of the same object data from the database.
$blogEntry = new AnyModelObject();
$id = 'some-unique-id-here';
$identityMap = new Pimf\Util\IdentityMap();
if (true === $identityMap->hasId($id)) {
return $identityMap->getObject($id);
}
Setting objects/instances inti the identity map.
$identityMap->set($id, $blogEntry);
if (true === $identityMap->hasObject($blogEntry)) {
throw new RuntimeException('Object has an ID, cannot insert.');
}
