([SLING-5664](https://issues.apache.org/jira/browse/SLING-5664)) the service
with the highest service ranking is returned. In case multiple services are
returned, they are ordered descending by their service ranking (i.e. the one
with the highest ranking first). | Any object | yes | yes | Parameterized

Sling Object | `sling-object` | `Integer.MAX_VALUE` | 1.1.0
| Injects commonly used sling objects if the
field matches with the class: request, response, resource resolver, current
resource, SlingScriptHelper. This works only if the adaptable can get the
according information, i.e. all objects are available via
`SlingHttpServletRequest` while `ResourceResolver` can only resolve the
`ResourceResolver` object and nothing else. A discussion around this limitation
can be found at [SLING-4083](https://issues.apache.org/jira/browse/SLING-4083).
Also `Resource`s can only be injected if the according injector-specific
annotation is used (`@SlingObject`). | `Resource`, `ResourceResolver` or
`SlingHttpServletRequest` objects (not all objects can be resolved by all
adaptables). | yes | none | none
