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 interfaceSortedKeyValueIterator<Key,Value>
- Overrides:
deepCopy
in classFilter
- Parameters:
env
-IteratorEnvironment
environment in which iterator is being run, provided by Accumulo itself and is expected to be non-null.- Returns:
SortedKeyValueIterator
a copy of this iterator (with the same source and settings).
