Method Detail

grabMultiple

public IRepositoryConnector[] grabMultiple(java.lang.String[] orderingKeys,
                                           IRepositoryConnection[] repositoryConnections)
                                    throws ManifoldCFException

Get multiple repository connectors, all at once. Do this in a particular order so that any connector exhaustion will not cause a deadlock.

Specified by:

grabMultiple in interface IRepositoryConnectorPool

Parameters:

orderingKeys - are the keys which determine in what order the connectors are obtained.

repositoryConnections - are the connections to use the build the connector instances.

Throws:

ManifoldCFException

grab

public IRepositoryConnector grab(IRepositoryConnection repositoryConnection)
                          throws ManifoldCFException

Get a repository connector. The connector is specified by a repository connection object.

Specified by:

grab in interface IRepositoryConnectorPool

Parameters:

repositoryConnection - is the repository connection to base the connector instance on.

Throws:

ManifoldCFException

releaseMultiple

public void releaseMultiple(IRepositoryConnection[] connections,
                            IRepositoryConnector[] connectors)
                     throws ManifoldCFException

Release multiple repository connectors.

Specified by:

releaseMultiple in interface IRepositoryConnectorPool

Parameters:

connections - are the connections describing the instances to release.

connectors - are the connector instances to release.

Throws:

ManifoldCFException

release

public void release(IRepositoryConnection connection,
                    IRepositoryConnector connector)
             throws ManifoldCFException

Release a repository connector.

Specified by:

release in interface IRepositoryConnectorPool

Parameters:

connection - is the connection describing the instance to release.

connector - is the connector to release.

Throws:

ManifoldCFException

pollAllConnectors

public void pollAllConnectors()
                       throws ManifoldCFException

Idle notification for inactive repository connector handles. This method polls all inactive handles.

Specified by:

pollAllConnectors in interface IRepositoryConnectorPool

Throws:

ManifoldCFException

flushUnusedConnectors

public void flushUnusedConnectors()
                           throws ManifoldCFException

Flush only those connector handles that are currently unused.

Specified by:

flushUnusedConnectors in interface IRepositoryConnectorPool

Throws:

ManifoldCFException

closeAllConnectors

public void closeAllConnectors()
                        throws ManifoldCFException

Clean up all open repository connector handles. This method is called when the connector pool needs to be flushed, to free resources.

Specified by:
