All Implemented Interfaces:: Map<Object,Object>, Container

public final class FastIteratingContainer extends Object implements Container

The FastIteratingContainer implementation of the Container interface assuems two things:

Puts and removes are rare in proportion to gets and iteration are common. Put and remove are much more expensive here than in MapContainer.
Keys will not be reused (using a key twice with different values implicitly does an expensive remove).

In order for allow for removes and adds to be called while an iterator is in use, iterator-responses use cloned key/value lists.

- FastIteratingContainer
  
  public FastIteratingContainer()
Method Details
- updateTimestamp
  
  public void updateTimestamp()
  
  Set the timestamp of this container to System.currentTimeMillis().
  
  Specified by:
  
  updateTimestamp in interface Container
- getTimestamp
  
  public long getTimestamp()
  
  Returns the timestamp of this container.
  
  Specified by:
  
  getTimestamp in interface Container
  
  Returns:
  
  The timestamp.
- keyIterator
  
  public Iterator<Object> keyIterator()
  
  Returns an iterator over the keys contained in this container. If the container is modified while an iteration is in progress, the results of the iteration is not affected and vice-versa.
  
  Specified by:
  
  keyIterator in interface Container
  
  Returns:
  
  An iterator over the keys currently contained in the container.
- valueIterator
  
  public Iterator<Object> valueIterator()
  
  Returns an iterator over the values contained in this container. If the container is modified while an iteration is in progress, the results of the iteration is not affected and vice-versa.
  
  Specified by:
  
  valueIterator in interface Container
  
  Returns:
  
  An iterator over the values currently contained in the container.
- size
  
  public int size()
  
  Specified by:
  
  size in interface Map<Object,Object>
- isEmpty
  
  public boolean isEmpty()
  
  Specified by:
  
  isEmpty in interface Map<Object,Object>
- containsKey

  Specified by:
  
  containsKey in interface Map<Object,Object>
- containsValue
  
  public boolean containsValue(Object value)
  
  Specified by:

  Specified by:
  
  remove in interface Map<Object,Object>
