Container::register() │ public │ WC 1.0

Interface for registering a new dependency with the container.

By default, the $value will be added as a shared dependency. This means that it will be a single instance shared among any other classes having that dependency.

If you want a new instance every time it's required, then wrap the value in a call to the factory method (@see Container::factory for example)

Note: Currently if the provided id already is registered in the container, the provided value is ignored.

Method of the class: Container{}

No Hooks.

Return

null. Nothing (null).

Usage

$Container = new Container();
$Container->register( $id, $value );
$id(string) (required)
A unique string identifier for the provided value. Typically it's the fully qualified name for the dependency.
$value(mixed) (required)
The value for the dependency. Typically, this is a closure that will create the class instance needed.
