public class NodeEngineImpl extends Object implements NodeEngine
But the crucial thing is that we don't want to leak concrete dependencies to the outside. For example
we don't leak OperationServiceImpl
to the outside.

public MemberImpl getLocalMember()
NodeEngine
The returned value will never be null but it may change when local lite member is promoted to a data member or when this member merges to a new cluster after split-brain detected. Returned value should not be cached but instead this method should be called each time when local member is needed.

public Operation[] getPostJoinOperations()
PostJoinAwareService
s.
Post join operations should return response, at least a null
response.
Note: Post join operations must be lock free, meaning no locks at all:
no partition locks, no key-based locks, no service level locks, no database interaction!
The Operation.getPartitionId()
method should return a negative value.
This means that the operations should not implement PartitionAwareOperation
.
