updateTopology

public Topology updateTopology(Topology topology,
                      boolean detectConflict,
                      boolean commit)
                        throws com.vordel.api.nm.NodeManagerAPIException

Aimed at internal use only. This method will overwrite the current topology with a new topology. The equivalent server-side method is invoked internally by one Node Manager on all others when a topology update needs to be propagated to all Node Managers. The Node Manager that is pushing the topology change out to all other Node Managers will firstly invoke this method with commit=false and detectConflict=true. A commit is now pending (subject to a timeout) in all Node Managers. If all Node Managers return successfully, the same controlling Node Manager will call this method again with commit=true and detectConflict=true. The Node Managers that receive this call will then commit the topology changes. While a commit is pending, a Node Manager cannot process any other updates. In a client application this method could be used to push a topology out to all Node Managers.

Parameters:

topology - The new topology

detectConflict - If this flag is true the Node Manager should only accept in-synch updates, i.e. if the current version is n, the new version must be n+1.

commit - Set to false if this is a pending update. Set to true if the update should be committed. A commit=false is sent before a commit=true request.

Returns:

Throws:

com.vordel.api.nm.NodeManagerAPIException
