* The format of this dumper is very similar to the internal structure of the

* ContainerBuilder, but based on PHP arrays and \stdClass objects instead of
|
||||
* rich value objects for performance reasons.
|
||||
*

* By removing the abstraction and optimizing some cases like deep collections,

* fewer classes need to be loaded, fewer function calls need to be executed and
|
||||
* fewer run time checks need to be made.
|
||||
*
|
||||
* In addition to that, this container dumper treats private services as
|
||||
* strictly private with their own private services storage, whereas in the
|
||||
* Symfony service container builder and PHP dumper, shared private services can
|
||||
* still be retrieved via get() from the container.
|
||||
*
|
||||
* It is machine-optimized, for a human-readable version based on this one see
|

* \Drupal\Component\DependencyInjection\Dumper\PhpArrayDumper.
