GenericReplicaState

All Known Implementing Classes:

CausalContext, VVContext
```
public interface VVState
extends GenericReplicaState
```
Replica state that stores a version version for causal context. The implementations should support the updating of the version vector through timestamps and other version vectors.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`VersionVector`	`getVV()` Gets the version vector stored in the state.
`VersionVector`	`getVVCopy()` Gets a copy of the version vector stored in the state.
`Integer`	`getVVEntry(ReplicaID otherReplicaID)`
`Timestamp`	`incClock()` Increments the "clock" of the replica (i.e., increments the specific entry of the replica in question) by generating a new timestamp
`void`	`mergeTs(Timestamp ts)` Method called when merging the state with other replica.
`void`	`updateTs(Timestamp ts)` Updates the replica's version vector with a given timestamp.
`void`	`updateVV(VersionVector vv)` Updates the replica's version vector with a given version vector.

- Method Detail
  - getVVCopy
```
VersionVector getVVCopy()
```
    Gets a copy of the version vector stored in the state.
    
    Returns:
    
    the version vector
  - getVV
```
VersionVector getVV()
```
    Gets the version vector stored in the state.
    
    Returns:
    
    the version vector
  - incClock
```
Timestamp incClock()
```
    Increments the "clock" of the replica (i.e., increments the specific entry of the replica in question) by generating a new timestamp
    
    Returns:
    
    the newly created timestamp
  - updateTs
```
void updateTs(Timestamp ts)
```
    Updates the replica's version vector with a given timestamp. The update only occurs if the timestamp is superior to the entry of the replica.
    
    Parameters:
    
    ts - the timestamp to integrate into the version vector.
  - updateVV
```
void updateVV(VersionVector vv)
```
    Updates the replica's version vector with a given version vector. The update only occurs if the any of the entries are superior to replica own entries.
    
    Parameters:
    
    vv - the version vector received.
  - mergeTs
```
void mergeTs(Timestamp ts)
```
    Method called when merging the state with other replica. It acts as a wrapper to updateTs when the argument passed is not a null.
    
    Parameters:
    
    ts - the timestamp to update.
  - getVVEntry
```
Integer getVVEntry(ReplicaID otherReplicaID)
```
