kandi X-RAY | lazy-collections Summary
Fast and lazy collection operations. Working with methods like .map(), .filter() and .reduce() is nice, however they create new arrays and everything is eagerly done before going to the next step. This is where lazy collections come in, under the hood we use iterators and async iterators so that your data flows like a stream to have the optimal speed.

I have a post collection class which has some utility for filtering and mapping data.

Answered 2019-Feb-25 at 13:27What you've found is doc for Doctrine Collections package.
Doctrine ORM is using Doctrine Collections package, but they are separate packages from each other. Therefore the fact that you can create a custom collection doesn't mean ORM will respect that.
What you want to do is not possible right now with Doctrine ORM.
The feature of custom collections is scheduled for next major Doctrine ORM version.
