Interface ServiceUserMapper

@ProviderType
public interface ServiceUserMapper

The ServiceUserMapper service can be used to map a service provided by a bundle to the ID of a user account used to access the ResourceResolver used by the service to access its data.

The goal of this service is to allow services to be implemented accessing the storage with service-specific accounts which are tailored to allow the service appropriate access without requiring administrative level access to the storage.

In general a service is implement in a single bundle such as the JSP compiler bundle. Other services may be implemented in multiple bundles. In certain cases there may be sub-services requiring different access levels. For example a couple of bundles may implement a "mail" service where each bundle implements a part of the service such as the "smtp", "queuing", and "delivery" sub services. Such sub services are identified with the subServiceName parameter on the method calls.

In addition to allowing to phase out the use of ResourceResolver.getAdministrativeResourceResolver and SlingRepository.loginAdministrative it also allows to better account for changes to the storage by the different services.

This service is not intended to be used by the general user but by implementations of the ResourceResolverFactory and SlingRepository services.

This service is not intended to be implemented by clients.

Method Summary

Modifier and Type	Method and Description
java.util.List<Mapping>	getActiveMappings() Returns a list of all of the active mappings in the Service User Mapper.
java.lang.Iterable<java.lang.String>	getServicePrincipalNames(Bundle bundle, java.lang.String subServiceName) Returns the principal names to access the data store on behalf of the service.

Method Detail

getServiceUserID

java.lang.String getServiceUserID(Bundle bundle,
                                  java.lang.String subServiceName)

Returns the ID of a user to access the data store on behalf of the service.

Parameters:

bundle - The bundle implementing the service request access to resources.

subServiceName - Name of the sub service. This parameter is optional and may be an empty string or null.

Returns:

The ID of the user to use to provide access to the resources for the service. This may be null if no particular user can be derived for the service identified by the bundle and the optional serviceInfo.

getServicePrincipalNames

java.lang.Iterable<java.lang.String> getServicePrincipalNames(Bundle bundle,
                                                              java.lang.String subServiceName)

Returns the principal names to access the data store on behalf of the service.

Parameters:

bundle - The bundle implementing the service request access to resources.

subServiceName - Name of the sub service. This parameter is optional and may be an empty string or null.

Returns:

The principal names to use to provide access to the resources for the service. This may be null if no mapping has been defined for the service identified by the bundle and the optional serviceInfo or if no principal names have been specified with the mapping. In this case getServiceUserID(Bundle, String) should be used instead.

getActiveMappings

java.util.List<Mapping> getActiveMappings()

Returns a list of all of the active mappings in the Service User Mapper.

Returns:

A list of the currently active mapped Service users
