Technically Null Container
==========================

[](#technically-null-container)

`Technically\NullContainer` is a [PSR-11](https://www.php-fig.org/psr/psr-11/) container implementation that is always empty.

This is a [NullObject](https://en.wikipedia.org/wiki/Null_object_pattern) pattern implementation for PSR-11.

This is useful when you want to provide an optional `ContainerInterface` dependency, but don't want to deal with nullable values.
