Method Detail

getCoordinators

public java.util.Vector getCoordinators(java.lang.Object resId)

migrateCoordinationFrom

public void migrateCoordinationFrom(java.lang.Object resId,
                                    java.io.Serializable nodeId)
                             throws NotCoordinatorException,
                                    AlreadyCoordinatorException

Migrates the coordination of a resource from a remote node to the local one. This operation do preserve the guaranteed order of message delivery, so that the migration must be completely transparent to users and coordinators.

Parameters:

resId - the id of the related resource

nodeId - id of the node from which the coordination is to be moved

Throws:

NotCoordinatorException - if the designated node is not a coord.

AlreadyCoordinatorException - if the local node is already a coordinator

copyCoordinationFrom

public void copyCoordinationFrom(java.lang.Object resId,
                                 java.io.Serializable nodeId)
                          throws NotCoordinatorException,
                                 AlreadyCoordinatorException

Replicates the coordination of a resource from a remote node to the local one. This operation do preserve the guaranteed order of message delivery, so that the replication must be completely transparent to users and coordinators.

Parameters:

resId - the id of the related resource

nodeId - the id of the node from which the coordination is to be replicated

Throws:

NotCoordinatorException - if the designated node is not a coordinator

AlreadyCoordinatorException - if the local node is already a coordinator

getNodeId

public java.io.Serializable getNodeId()

Returns the id of the local node which can be sent in messages as it is serializable.

Returns:

the id of the local node
