Deprecated.

as of API version 2.3 (bundle version 2.2.2). Use AbstractSlingRepositoryManager and AbstractSlingRepository2 instead.

@Deprecated
 @ProviderType
public abstract class AbstractSlingRepository
extends AbstractNamespaceMappingRepository
implements SlingRepository, Runnable

The AbstractSlingRepository is an abstract implementation of the SlingRepository interface which provides default support for attached repositories as well as ensuring live repository connection, reconnecting if needed. Implementations of the SlingRepository interface may wish to extend this class to benefit from a default implementation.

As of version 2.2 (bundle version 2.2.0) the registration of repository services based on this abstract base class works differently. To be able to know the calling bundle to implement the loginService(String, String) method the service is registered as a service factory. Yet this component is registered as a non-service component with Declarative Services handling its registration itself so the the ServiceFactory cannot simply create instances of this class. The solution is for the service factory to create a proxy to the actual component object. All method calls are just routed through with the exception of the loginService(String, String) method which is routed to a new internal method taking the calling bundle as an additional argument.

The changes to support this new registration mechanism are as follows:

• The registerService() method is now final.
• The getServiceRegistrationInterfaces() and getServiceRegistrationProperties() methods have been added and can be overwritten by implementations of this class. The registerService() method calls these new methods to get the interfaces and properties for the service registration.

Implementations of this class overwriting the registerService() method must replace this overwritten method with overwriting the new getServiceRegistrationInterfaces() and/or getServiceRegistrationProperties() methods.

Description copied from interface: SlingRepository

Returns a session to the given workspace which has administrative powers.

NOTE: This method is intended for use by infrastructure bundles to access the repository and provide general services. This method MUST not be used to handle client requests of whatever kinds. To handle client requests a regular authenticated session retrieved through Repository.login(javax.jcr.Credentials, String) or Session.impersonate(javax.jcr.Credentials) must be used.

This method is deprecated. Services running in the Sling system should use the SlingRepository.loginService(String serviceInfo, String workspace) method instead. Implementations of this method must throw javax.jcr.LoginException if they don't support it.

Specified by:

loginAdministrative in interface SlingRepository

Parameters:

workspace - The name of the workspace to which to get an administrative session. If null the SlingRepository.getDefaultWorkspace() default workspace is assumed.

Returns:

The administrative Session

Throws:

javax.jcr.LoginException - If this method is not supported or is disabled by the implementation.

javax.jcr.RepositoryException - If an error occurs creating the administrative session

loginService

public final javax.jcr.Session loginService(String subServiceName,
                                            String workspace)
                                     throws javax.jcr.LoginException,
                                            javax.jcr.RepositoryException

Deprecated.

This method always throws LoginException because it does not directly have the calling bundle at its disposition to decide on the required service name.

This method is final and cannot be overwritten by extensions. See the class comments for full details on how this works.

Specified by:

loginService in interface SlingRepository

Parameters:

subServiceName - Optional Subservice Name to specialize account selection for the service. This may be null.

workspace - The name of the workspace to which to get an administrative session. If null the SlingRepository.getDefaultWorkspace() default workspace is assumed.

Returns:

A Session with appropriate permissions to execute the service.

Throws:

javax.jcr.LoginException - If there is no service account defined for the calling bundle or the defined service account does not exist.

javax.jcr.RepositoryException - if an error occurs.

getRepositoryAccessor

protected RepositoryAccessor getRepositoryAccessor()

Deprecated.

Returns a new instance of the RepositoryAccessor class to access a repository over RMI or through JNDI.

Extensions of this method may return an extension of the RepositoryAccessor class if the provide extended functionality.

acquireRepository

protected javax.jcr.Repository acquireRepository()

Deprecated.

Acquires the repository by calling the RepositoryAccessor.getRepositoryFromURL(String) with the value of the RepositoryAccessor.REPOSITORY_URL_OVERRIDE_PROPERTY framework or configuration property. If the property exists and a repository can be accessed using this property, that repository is returned. Otherwise null is returned.

Extensions of this class may overwrite this method with implementation specific acquisition semantics and may call this base class method or not as the implementation sees fit.

This method does not throw any Throwable but instead just returns null if not repository is available. Any problems trying to acquire the repository must be caught and logged as appropriate.

Returns:

The acquired JCR Repository or null if not repository can be acquired.

setupRepository

protected void setupRepository(javax.jcr.Repository repository)

Deprecated.

This method is called after a repository has been acquired by acquireRepository() but before the repository is registered as a service.

Implementations may overwrite this method but MUST call this base class implementation first.

Parameters:

repository - The JCR Repository to setup.

registerService

protected final org.osgi.framework.ServiceRegistration registerService()

Deprecated.

Registers this component as an OSGi service with the types provided by the getServiceRegistrationInterfaces() method and properties provided by the getServiceRegistrationProperties() method.

As of version 2.2 (bundle version 2.2.0) this method is final and cannot be overwritten because the mechanism of service registration using a service factory is required to fully implement the loginService(String, String) method. See the class comments for full details on how this works.

Returns:

The OSGi ServiceRegistration object representing the registered service.

getServiceRegistrationProperties

protected Dictionary<String,Object> getServiceRegistrationProperties()

Deprecated.

Return the service registration properties to be used to register the repository service in registerService().

This method may be overwritten to return additional service registration properties. But it is strongly recommended to always include the properties returned from this method.

Returns:

The service registration properties to be used to register the repository service in registerService()

Since:

2.2 (bundle version 2.2.0)

getServiceRegistrationInterfaces

protected String[] getServiceRegistrationInterfaces()

Deprecated.

Returns the service types to be used to register the repository service in registerService(). All interfaces returned must be accessible to the class loader of the class of this instance.

This method may be overwritten to return additional types but the types returned from this base implementation must always be included.

Returns:

The service types to be used to register the repository service in registerService()

Since:

2.2 (bundle version 2.2.0)

getRepository

protected javax.jcr.Repository getRepository()

Deprecated.

Returns the repository underlying this instance or null if no repository is currently being available.

pingRepository

protected boolean pingRepository(javax.jcr.Repository repository)

Deprecated.

Checks that the given repository is still available. This implementation tries to get the Repository.SPEC_NAME_DESC descriptor from the repository and returns true if the returned value is not null.

Extensions of this class may overwrite this method to implement different access checks. The contract of this method must be obeyed, though in a sense, the true must only be returned if repository is actually usable.

Parameters:

repository - The JCR Repository to check for availability.

Returns:

true if repository is not null and accessible.

pingAndCheck

protected boolean pingAndCheck()

Deprecated.

Ping our current repository and check that admin login (required by Sling) works.

tearDown

protected void tearDown(javax.jcr.Repository repository)

Deprecated.

Performs any cleanups before the repository is actually disposed off by the disposeRepository(Repository) method.

This method is meant for cleanup tasks before the repository is actually disposed off. Extensions of this class may overwrite but must call this base class implementation.

Parameters:
