Method Details

init

public final void init()
                throws RepositoryException

Description copied from interface: Repository

Initializes this repository. A repository needs to be initialized before it can be used, however explicitly calling this method is not necessary: the repository will automatically initialize itself if an operation is executed on it that requires it to be initialized.

Specified by:

init in interface Repository

Throws:

RepositoryException - If the initialization failed.

initializeInternal

protected abstract void initializeInternal()
                                    throws RepositoryException

Throws:

RepositoryException

shutDown

public final void shutDown()
                    throws RepositoryException

Description copied from interface: Repository

Shuts the repository down, releasing any resources that it keeps hold of. Once shut down, the repository can no longer be used until it is re-initialized.

Specified by:

shutDown in interface Repository

Throws:

RepositoryException

isInitialized

public final boolean isInitialized()

Description copied from interface: Repository

Indicates if the Repository has been initialized. Note that the initialization status may change if the Repository is shut down.

Specified by:

isInitialized in interface Repository

Returns:

                                  throws RepositoryException
