- Method Detail
  - accept
```
public boolean accept(Key key,
                      Value v)
```
    Specified by:
    
    accept in class ServerFilter
    
    Returns:
    
    true if the key/value pair is accepted by the filter.
  - deepCopy
```
public SortedKeyValueIterator<Key,Value> deepCopy(IteratorEnvironment env)
```
    Description copied from interface: SortedKeyValueIterator
    
    Creates a deep copy of this iterator as though seek had not yet been called. init should be called on an iterator before deepCopy is called. init should not need to be called on the copy that is returned by deepCopy; that is, when necessary init should be called in the deepCopy method on the iterator it returns. The behavior is unspecified if init is called after deepCopy either on the original or the copy. A proper implementation would call deepCopy on the source.
    
    Specified by:
    
    deepCopy in interface SortedKeyValueIterator<Key,Value>
    
    Specified by:
    
    deepCopy in class ServerFilter
    
    Parameters:
    
    env - IteratorEnvironment environment in which iterator is being run.
    
    Returns:
    
    SortedKeyValueIterator a copy of this iterator (with the same source and settings).
  - wrap
```
public static SortedKeyValueIterator<Key,Value> wrap(SortedKeyValueIterator<Key,Value> source,
                                                           Set<Column> cols)
```
