Class ResourceSynchronizer<R extends Resource<R,N>,N extends ResourceNode<R,N>>

Direct Known Subclasses:

public abstract class ResourceSynchronizer<R extends Resource<R,N>,N extends ResourceNode<R,N>> extends Object

Each resource has one synchronizer between it and any other node for the resource.

Every resource type should support testing. The test should ensure point-in-time consistency between two nodes as much as possible.

Resources are only required to support synchronization when is a master. They may optionally support synchronization when a slave (such as a csync2 master on a slave node).
