java.lang.Object

org.apache.manifoldcf.authorities.mappingconnectorpool.MappingConnectorPool

All Implemented Interfaces:

IMappingConnectorPool

public class MappingConnectorPool
extends java.lang.Object
implements IMappingConnectorPool

An implementation of IMappingConnectorPool. Coordination and allocation among cluster members is managed within. These objects are thread-local, so do not share them among threads.

Method Detail

grabMultiple

public IMappingConnector[] grabMultiple(java.lang.String[] orderingKeys,
                                        IMappingConnection[] mappingConnections)
                                 throws ManifoldCFException

Get multiple mapping 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 IMappingConnectorPool

Parameters:

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

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

Throws:

ManifoldCFException

grab

public IMappingConnector grab(IMappingConnection mappingConnection)
                       throws ManifoldCFException

Get a mapping connector. The connector is specified by an mapping connection object.

Specified by:

grab in interface IMappingConnectorPool

Parameters:

mappingConnection - is the mapping connection to base the connector instance on.

Throws:

ManifoldCFException

releaseMultiple

public void releaseMultiple(IMappingConnection[] connections,
                            IMappingConnector[] connectors)
                     throws ManifoldCFException

Release multiple mapping connectors.

Specified by:

releaseMultiple in interface IMappingConnectorPool

Parameters:

connections - are the connections describing the instances to release.

connectors - are the connector instances to release.

Throws:

ManifoldCFException

release

public void release(IMappingConnection connection,
                    IMappingConnector connector)
             throws ManifoldCFException

Release a mapping connector.

Specified by:

release in interface IMappingConnectorPool

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 mapping connector handles. This method polls all inactive handles.

Specified by:

pollAllConnectors in interface IMappingConnectorPool

Throws:

ManifoldCFException

flushUnusedConnectors

public void flushUnusedConnectors()
                           throws ManifoldCFException

Flush only those connector handles that are currently unused.

Specified by:

flushUnusedConnectors in interface IMappingConnectorPool

Throws:

ManifoldCFException

closeAllConnectors

public void closeAllConnectors()
                        throws ManifoldCFException

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

Specified by:

closeAllConnectors in interface IMappingConnectorPool

Throws:

ManifoldCFException
