    • EvictingBackupMap

      public EvictingBackupMap()
      Default constructor.
  • Method Details

    • get

      public Object get(Object oKey)
      Returns the value to which this map maps the specified key.
      Specified by:
      get in interface Map
      Specified by:
      get in class AbstractKeyBasedMap
      Parameters:
      oKey - the key object
      Returns:
      the value to which this map maps the specified key, or null if the map contains no mapping for this key
    • put

      public Object put(Object oKey, Object oValue)
      Associates the specified value with the specified key in this map.
      Specified by:
      put in interface Map
      Overrides:
      put in class AbstractKeyBasedMap
      Parameters:
      oKey - key with which the specified value is to be associated
      oValue - value to be associated with the specified key
      Returns:
      previous value associated with specified key, or null if there was no mapping for key
    • remove

      public Object remove(Object oKey)
      Removes the mapping for this key from this map if present. Expensive: updates both the underlying cache and the local cache.
      Specified by:
      remove in interface Map
      Overrides:
      remove in class AbstractKeyBasedMap
      Parameters:
      oKey - key whose mapping is to be removed from the map
      Returns:
      previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.
    • iterateKeys

      protected Iterator iterateKeys()
      Create an iterator over the keys in this Map. The Iterator must support remove() if the Map supports removal.
      Specified by:
      iterateKeys in class AbstractKeyBasedMap
      Returns:
      a new instance of an Iterator over the keys in this Map
