A unique object used for retrieving items from the <a href='Injector-class.html'><code>Injector</code></a>.
|
|
|
|
|
|
|
|
|
|
Keys have:
|
|
|
|
|
- a system-wide unique `id`.
|
|
|
|
|
- a `token`, usually the `Type` of the instance.
|
|
|
|
|
|
|
|
|
|
Keys are used internally by the <a href='Injector-class.html'><code>Injector</code></a> because their system-wide unique `id`s allow the
|
|
|
|
|
injector to index in arrays rather than looking up items in maps.
