```
public Keyspaces withAddedOrUpdated(KeyspaceMetadata keyspace)

  - withAddedOrReplaced
```
public Keyspaces withAddedOrReplaced(KeyspaceMetadata keyspace)
```
    Returns a new Keyspaces equivalent to this one, but with the provided keyspace metadata either added (if this Keyspaces does not have that keyspace), or replaced by the provided definition.
    Note that if this contains the provided keyspace, its pre-existing definition is discarded and completely replaced with the newly provided one. See withAddedOrUpdated(KeyspaceMetadata) if you wish the provided definition to be "merged" with the existing one instead.
    
    Parameters:
    
    keyspace - the keyspace metadata to add, or replace the existing definition with.
    
    Returns:
    
    the newly created object.
  - withAddedOrReplaced
```
public Keyspaces withAddedOrReplaced(Keyspaces keyspaces)
```
    Calls withAddedOrReplaced(KeyspaceMetadata) on all the keyspaces of the provided Keyspaces.
    
    Parameters:
    
    keyspaces - the keyspaces to add, or replace if existing.
    
    Returns:
    
    the newly created object.
