Method Detail

grabMultiple

IRepositoryConnector[] grabMultiple(java.lang.String[] orderingKeys,
                                    IRepositoryConnection[] authorityConnections)
                             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.

Parameters:

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

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

Throws:

ManifoldCFException

grab

IRepositoryConnector grab(IRepositoryConnection repositoryConnection)
                   throws ManifoldCFException

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

Parameters:

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

Throws:

ManifoldCFException

releaseMultiple

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

Release multiple repository connectors.

Parameters:

connections - are the connections describing the instances to release.

connectors - are the connector instances to release.

Throws:

ManifoldCFException

release

void release(IRepositoryConnection connection,
             IRepositoryConnector connector)
      throws ManifoldCFException

Release a repository connector.

Parameters:

connection - is the connection describing the instance to release.

connector - is the connector to release.

Throws:

ManifoldCFException

pollAllConnectors

void pollAllConnectors()
                throws ManifoldCFException

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

Throws:

ManifoldCFException

flushUnusedConnectors

void flushUnusedConnectors()
                    throws ManifoldCFException

Flush only those connector handles that are currently unused.

Throws:

ManifoldCFException

closeAllConnectors

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.

Throws:

ManifoldCFException
