Sling Models Injectors
The AEM Library provides several custom Sling Models injectors to facilitate injection of AEM Library-specific context objects. Injector services are registered by default when the AEM Library Models bundle is installed, so @Inject annotated fields in model classes will be handled by the injectors below in addition to the default set of injectors provided by Sling.
