Class IBSkipIterator<K extends Comparable<? super K>,V>

java.lang.Object

net.metanotion.util.skiplist.SkipIterator<K,V>

net.metanotion.io.block.index.IBSkipIterator<K,V>

All Implemented Interfaces:

Iterator<V>, ListIterator<V>

public class IBSkipIterator<K extends Comparable<? super K>,V>
extends SkipIterator<K,V>

I2P Overridden to load the span when required and null out the keys and values when the iterator leaves the span. If the caller does not iterate all the way through, the last span will remain in memory.
