Count aggregates

At some point you may need to count the number of aggregates stored. You can do it like this:

$count = $orm->repository(User::class)->size();

This will return 0 or more.

And sometime you may need to simply know if there's at least one aggregate or none. For this case you should not use the size method as it overfetches data. Instead you can do:

$trueWhenTheresAtLeastOneUser = $orm->repository(User::class)->any();
// or
$trueWhenTheresNoUser = $orm->repository(User::class)->none();

Note

If you want to count the number of aggregates corresponding to a set of criteria head to the Specification chapter.
