Package net.metanotion.io.block.index

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.

Method Details

next

public V next()

Specified by:

next in interface Iterator<K extends Comparable<? super K>>

Specified by:

next in interface ListIterator<K extends Comparable<? super K>>

Overrides:

next in class SkipIterator<K extends Comparable<? super K>,V>

Returns:

the next value, and advances the index

NoSuchElementException

RuntimeException - on IOE

nextKey

public K nextKey()

The key. Does NOT advance the index.

Overrides:

nextKey in class SkipIterator<K extends Comparable<? super K>,V>

Returns:

the key for which the value will be returned in the subsequent call to next()

Throws:

NoSuchElementException

RuntimeException - on IOE

previous

public V previous()

Specified by:

previous in interface ListIterator<K extends Comparable<? super K>>

Overrides:

previous in class SkipIterator<K extends Comparable<? super K>,V>

Returns:

the previous value, and decrements the index

Throws:

NoSuchElementException

RuntimeException - on IOE
