Interface ResourceContext

public interface ResourceContext

The resource context provides access to instances of resource classes.

This interface can be injected using the Context annotation.

The resource context can be utilized when instances of managed resource classes are to be returned by sub-resource locator methods. Such instances will be injected and managed within the declared scope just like instances of root resource classes.

resourceClass - the resource class.

Returns:

an instance if it could be resolved, otherwise null.

initialized (same) resource instance.
