TabletStateChangeIterator
public TabletStateChangeIterator()
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.
consume
protected void consume()
throws IOException
- Specified by:
consume
in class SkippingIterator
- Throws:
IOException
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).
