public class AddOperation extends AbstractPNCounterOperation implements MutatingOperation
PNCounter
.
The session consistency guarantees are provided by sending a last-observed
vector clock with each operation. The operation response will contain the
current replica vector clock.name

name
- the name of the PNCounterdelta
- the delta to add to the counter value, can be negativegetBeforeUpdate
- true
if the operation should return the
counter value before the addition, false
if it should return the value after the additionobservedClock
- previously observed vector clock, may be null
