Class TransientRepository

java.lang.Object
  org.apache.jackrabbit.commons.AbstractRepository
      org.apache.jackrabbit.core.TransientRepository

All Implemented Interfaces:

Repository, JackrabbitRepository, SessionListener

public class TransientRepository
extends AbstractRepository
implements JackrabbitRepository, SessionListener

A repository proxy that automatically initializes and shuts down the underlying repository instance when the first session is opened or the last one closed. As long as all sessions are properly closed when no longer used, this class can be used to avoid having to explicitly shut down the repository.

Constructor Detail

TransientRepository

public TransientRepository(TransientRepository.RepositoryFactory factory,
                           String home)

Creates a transient repository proxy that will use the given repository factory to initialize the underlying repository instances.

Parameters:

factory - repository factory

home - the path to the repository home directory.

TransientRepository

public TransientRepository()

Creates a transient repository proxy that will use the repository configuration file and home directory specified in system properties org.apache.jackrabbit.repository.conf and org.apache.jackrabbit.repository.home. If these properties are not found, then the default values "repository.xml" and "repository" are used.

TransientRepository

public TransientRepository(RepositoryConfig config)

Creates a transient repository proxy that will use the given repository configuration to initialize the underlying repository instance.

Parameters:

config - repository configuration

TransientRepository

public TransientRepository(String config,
                           String home)

Creates a transient repository proxy that will use the given repository configuration file and home directory paths to initialize the underlying repository instances.

Parameters:

config - repository configuration file

home - repository home directory

See Also:

TransientRepository(File, File)

TransientRepository

public TransientRepository(File dir)

Creates a transient repository proxy based on the given repository home directory and the repository configuration file "repository.xml" contained in that directory.

Parameters:

dir - repository home directory

Since:

Apache Jackrabbit 1.6

TransientRepository

public TransientRepository(File xml,
                           File dir)

Creates a transient repository proxy that will use the given repository configuration file and home directory paths to initialize the underlying repository instances. The repository configuration file is reloaded whenever the repository is restarted, so it is safe to modify the configuration when all sessions have been closed.

If the given repository configuration file does not exist, then a default configuration file is copied to the given location when the first session starts. Similarly, if the given repository home directory does not exist, it is automatically created when the first session starts. This is a convenience feature designed to reduce the need for manual configuration.

Parameters:

xml - repository configuration file

dir - repository home directory

Since:

Apache Jackrabbit 1.6

Method Detail

getHomeDir

public String getHomeDir()

Returns:

the path to the repository home directory.

getDescriptorKeys

public String[] getDescriptorKeys()

Returns the available descriptor keys. If the underlying repository is initialized, then the call is proxied to it, otherwise the static descriptor keys are returned.

Specified by:

getDescriptorKeys in interface Repository

Returns:

descriptor keys

getDescriptor

public String getDescriptor(String key)

Returns the identified repository descriptor. If the underlying repository is initialized, then the call is proxied to it, otherwise the static descriptors are used.

Specified by:

getDescriptor in interface Repository

Parameters:

key - descriptor key

Returns:

descriptor value

See Also:

Repository.getDescriptor(String)

getDescriptorValue

public Value getDescriptorValue(String key)

Specified by:

getDescriptorValue in interface Repository

getDescriptorValues

public Value[] getDescriptorValues(String key)

Specified by:

getDescriptorValues in interface Repository

isSingleValueDescriptor

public boolean isSingleValueDescriptor(String key)

Specified by:

isSingleValueDescriptor in interface Repository

login

public Session login(Credentials credentials,
                     String workspaceName)
              throws RepositoryException

Logs in to the content repository. Initializes the underlying repository instance if needed. The opened session is added to the set of open sessions and a session listener is added to track when the session gets closed.

Specified by:

login in interface Repository

Parameters:

credentials - login credentials

workspaceName - workspace name

Returns:

new session

Throws:

RepositoryException - if the session could not be created

See Also:

Repository.login(Credentials,String)

shutdown

public void shutdown()

Forces all active sessions to logout. Once the last session has logged out, the underlying repository instance will automatically be shut down.

Specified by:

shutdown in interface JackrabbitRepository

See Also:

Session.logout()

loggedOut

public void loggedOut(SessionImpl session)

Removes the given session from the set of open sessions. If no open sessions remain, then the underlying repository instance is shut down.

Specified by:

loggedOut in interface SessionListener

Parameters:

session - closed session

See Also:

SessionListener.loggedOut(SessionImpl)

loggingOut

public void loggingOut(SessionImpl session)

Ignored. Called when a Session is about to be 'closed' by calling Session.logout()

Specified by:

loggingOut in interface SessionListener

Parameters:

session - the Session that is about to be 'closed'
