Class PartitionSplittingBackingMap.PartitionedIterator

java.lang.Object
com.tangosol.util.Base
com.tangosol.util.AbstractStableIterator
com.tangosol.net.partition.PartitionSplittingBackingMap.PartitionedIterator

All Implemented Interfaces:

Iterator

Enclosing class:

PartitionSplittingBackingMap

public class PartitionSplittingBackingMap.PartitionedIterator

extends AbstractStableIterator

An Iterator designed to ensure that a stable copy of each partition's keys is available for the duration of the iteration over its keys. <p/> This is primarily intended for use with the BinaryMap, which does not provide thread-safe iterators if the BinaryMap continues to be modified while the iteration is occurring.

Constructor Summary

protected

PartitionSplittingBackingMap.PartitionedIterator(Map[] amap) Construct PartitionedIterator based on the specified array of maps, where each map contains data for one and only one partition.

Method Summary

protected void	advance() Advance to the next object.
protected void	remove(Object oPrev) Remove the specified item.

Constructor Detail

PartitionSplittingBackingMap.PartitionedIterator

protected PartitionSplittingBackingMap.PartitionedIterator(Map[] amap)

Construct PartitionedIterator based on the specified array of maps, where each map contains data for one and only one partition.

Parameters:

amap - an array of underlying maps

Method Detail

advance

protected void advance()

Advance to the next object. <p/> This method must be implemented by the concrete sub-class by calling AbstractStableIterator.setNext(java.lang.Object) if there is a next object.

Specified by:

advance in class AbstractStableIterator

remove

protected void remove(Object oPrev)

Remove the specified item. <p/> This is an optional operation. If the Iterator supports element removal, then it should implement this method, which is delegated to by the AbstractStableIterator.remove() method.

Overrides:

remove in class AbstractStableIterator

Parameters:

oPrev - the previously iterated object that should be removed
