FileCFSkippingIterator

FileCFSkippingIterator
protected FileCFSkippingIterator(SortedKeyValueIterator<Key,Value> src,
Set<ByteSequence> colFamSet,
boolean inclusive)
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.
- Specified by:
deepCopy in interface SortedKeyValueIterator<Key,Value>- Overrides:
deepCopy in class ColumnFamilySkippingIterator
- Parameters:
env - IteratorEnvironment environment in which iterator is being run.
- Returns:
- SortedKeyValueIterator a copy of this iterator (with the same source and settings).
