All Implemented Interfaces:
Enumeration, Iterator
Enclosing class:
PartitionSplittingBackingMap
public class PartitionSplittingBackingMap.PartitionedIterator extends com.oracle.coherence.common.collections.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 Details

    • PartitionedIterator

      protected 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 Details

    • advance

      protected void advance()
      Advance to the next object.

      This method must be implemented by the concrete sub-class by calling AbstractStableIterator.setNext(T) if there is a next object.

      Specified by:
      advance in class com.oracle.coherence.common.collections.AbstractStableIterator

    • remove

      protected void remove(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 com.oracle.coherence.common.collections.AbstractStableIterator
      Parameters:
      oPrev - the previously iterated object that should be removed
