public abstract class AbstractGroupImpl extends AbstractEntity implements AbstractGroup
Synchronization model. When changing and reading the group membership, this class uses internal synchronization to ensure atomic operations and the "happens-before" relationship for reads/updates from different threads. Sub-classes should not use this same synchronization mutex when doing expensive operations - e.g. if resizing a cluster, don't block everyone else from asking for the current number of members.
