Container
in package
PSR11 compliant dependency injection container for WooCommerce.
Classes in the src directory should specify dependencies from that directory via an 'init' method having arguments
with type hints. If an instance of the container itself is needed, the type hint to use is \Psr\Container\ContainerInterface.
Classes in the src directory should interact with anything outside (especially code in the includes directory
and WordPress functions) by using the classes in the Proxies directory. The exception is idempotent
functions (e.g. wp_parse_url), those can be used directly.
Classes in the includes directory should use the wc_get_container function to get the instance of the container when
they need to get an instance of a class from the src directory.
Internally, an instance of RuntimeContainer will be used for the actual class resolution. This class uses reflection to instantiate classes and figure out dependencies, so there's no need for explicit class registration. When running the unit tests suite this will be replaced with an instance of TestingContainer, which provides additional functionality.
