}

Description

Keys have:

• a system-wide unique id.
• a token.

Key is used internally by ReflectiveInjector because its system-wide unique id allows the injector to store created objects in a more efficient way.

Key should not be created directly. ReflectiveInjector creates keys automatically when resolving providers.
