Interface ReQueableToken<T extends ReQueableToken>

All Superinterfaces:

Chainable<T>, Comparable<T>, Displayable, FlowState, GUID, Notification, Serializable, Token<T>

public interface ReQueableToken<T extends ReQueableToken>
extends Token<T>

A Token aware of its neighbours in a Double linked list Q.

Useful if the Token implementation cannot simply rely on its initial state of sequence like Token.getId(), like it can be moved around.

USAGE CAUTION: One does not need to use this always; as the Current Q the ones served/processes anyway STATE changes and the ones in Q only count the READY ones.
This is only useful, if within the same state we wish to re-arrange or re-shuffle the order within the Q ; other than first cum first serve basis (natural id).
