                               throws StoreException

Specified by:

getMetaData in interface Repository

Throws:

StoreException

setDataDir

public void setDataDir(File dataDir)

Description copied from interface: Repository

Specified by:

setDataDir in interface Repository

Parameters:

dataDir - the directory where data for this repository is stored

getDataDir

public File getDataDir()

Description copied from interface: Repository

Get the directory where data and logging for this repository is stored.

Specified by:

Returns:

the directory where data for this repository is stored.

initialize

public void initialize()
                throws StoreException

Description copied from interface: Repository

Initializes this repository. A repository needs to be initialized before it can be used.

public RepositoryConnection getConnection()
                                   throws StoreException

Description copied from interface: Repository

Opens a connection to this repository that can be used for querying and updating the contents of the repository. Created connections need to be closed to make sure that any resources they keep hold of are released. The best way to do this is to use a try-finally-block as follows:

 Connection con = repository.getConnection();
 try {
        // perform operations on the connection
 }
 finally {
        con.close();
 }

A connection that allows operations on this repository.
