```
public CSNGenerator(int serverId,
                    long timestamp)
```
    Create a new CSNGenerator.
    
    Parameters:
    
    serverId - id to use when creating CSNs.
    
    timestamp - time to start with.
  - CSNGenerator
```
public CSNGenerator(int serverId,
                    ServerState state)
```
    Create a new CSNGenerator.
    
    Parameters:
    
    serverId - serverId to use when creating CSNs.
    
    state - This generator will be created in a way that makes sure that all CSNs generated will be larger than all the CSNs currently in state.
- Method Detail
  - newCSN
```
public CSN newCSN()
```
    Generate a new CSN.
    
    Returns:
    
    the generated CSN
  - adjust
```
public void adjust(CSN number)
```
    Adjust the lastTime of this CSNGenerator with a CSN that we have received from another server.
    This is necessary because we need that the CSN generated after processing an update received from other hosts to be larger than the received CSN
    
    Parameters:
    
    number - the CSN to adjust with
  - adjust
```
public void adjust(ServerState state)
```
    Adjust utility method that takes ServerState as a parameter.
    
    Parameters:
    
    state - the ServerState to adjust with
