SlowIterator
public SlowIterator()
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 WrappingIterator
- Parameters:
env
- IteratorEnvironment environment in which iterator is being run.
- Returns:
- SortedKeyValueIterator a copy of this iterator (with the same source and settings).
next
public void next()
throws IOException
- Description copied from interface:
SortedKeyValueIterator
- Advances 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.
- Specified by:
next
in interface SortedKeyValueIterator<Key,Value>
- Overrides:
next
in class WrappingIterator
- Throws:
IOException
- if an I/O error occurs.
init
public void init(SortedKeyValueIterator<Key,Value> source,
Map<String,String> options,
IteratorEnvironment env)
throws IOException
- Description copied from interface:
SortedKeyValueIterator
- Initializes the iterator. Data should not be read from the source in this method.
- Specified by:
init
in interface SortedKeyValueIterator<Key,Value>
- Overrides:
init
in class WrappingIterator
- Parameters:
source
- SortedKeyValueIterator source to read data from.options
- Map map of string option names to option values.env
- IteratorEnvironment environment in which iterator is being run.
- Throws:
IOException
- unused.
