java.lang.Object
  extended by com.tangosol.util.Base
      extended by com.tangosol.util.AbstractStableIterator

All Implemented Interfaces:
java.util.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.

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(java.util.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(java.lang.Object oPrev)
          Remove the specified item.

Constructor Detail

PartitionSplittingBackingMap.PartitionedIterator

protected PartitionSplittingBackingMap.PartitionedIterator(java.util.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.

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(java.lang.Object oPrev)
Remove the specified item.

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
