public CountingIterator deepCopy(IteratorEnvironment env)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.
public void init(SortedKeyValueIterator<Key,Value> source, Map<String,String> options, IteratorEnvironment env)Initializes the iterator. Data should not be read from the source in this method.
- Specified by:
SortedKeyValueIteratorsource to read data from.
Mapmap of string option names to option values.
IteratorEnvironmentenvironment in which iterator is being run.
public void next() throws IOExceptionAdvances to the next K,V pair. Note that in minor compaction scope and in non-full major compaction scopes the iterator may see deletion entries. These entries should be preserved by all iterators except ones that are strictly scan-time iterators that will never be configured for the minc or majc scopes. Deletion entries are only removed during full major compactions.
