Method Detail

getConnection

public RepositoryConnection getConnection()
                                   throws RepositoryException

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();
 }
 

Specified by:

getConnection in interface Repository

Returns:

A connection that allows operations on this repository.

Throws:

RepositoryException - If something went wrong during the creation of the Connection.

getDataDir

public File getDataDir()

Description copied from interface: Repository

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

Specified by:

getDataDir in interface Repository

Returns:

the directory where data for this repository is stored.

getValueFactory

public ValueFactory getValueFactory()

Description copied from interface: Repository

Gets a ValueFactory for this Repository.

Specified by:

getValueFactory in interface Repository

Returns:

A repository-specific ValueFactory.

initialize

public void initialize()
                throws RepositoryException

Description copied from interface: Repository

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

Specified by:

initialize in interface Repository

Throws:

RepositoryException - If the initialization failed.

isWritable

public boolean isWritable()
                   throws RepositoryException

Description copied from interface: Repository

Checks whether this repository is writable, i.e. if the data contained in this repository can be changed. The writability of the repository is determined by the writability of the Sail that this repository operates on.

Specified by:

isWritable in interface Repository

Throws:

RepositoryException

setDataDir

public void setDataDir(File dataDir)

Description copied from interface: Repository

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

Specified by:

setDataDir in interface Repository

Parameters:

dataDir - the directory where data for this repository is stored

shutDown

public 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

toString

public String toString()

Overrides:

toString in class Object

getAdditionalHttpHeaders

public Map<String,String> getAdditionalHttpHeaders()

Returns:

Returns the additionalHttpHeaders.

setAdditionalHttpHeaders

public void setAdditionalHttpHeaders(Map<String,String> additionalHttpHeaders)

Parameters:

additionalHttpHeaders - The additionalHttpHeaders to set as key value pairs.
