    • Method Detail

      • 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 SerializationMap
        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

      • putAll

        public void putAll​(Map map)
        Copies all of the mappings from the specified map to this map. The effect of this call is equivalent to that of calling AbstractKeyBasedMap.put(K, V) on this map once for each mapping in the passed map. The behavior of this operation is unspecified if the passed map is modified while the operation is in progress.
        Specified by:
        putAll in interface Map
        Overrides:
        putAll in class SerializationMap
        Parameters:
        map - the Map containing the key/value pairings to put into this Map

      • 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 SerializationMap
        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.

      • removeBlind

        protected boolean removeBlind​(Object oKey)
        Removes the mapping for this key from this map if present. This method exists to allow sub-classes to optimize remove functionality for situations in which the original value is not required.
        Overrides:
        removeBlind in class SerializationMap
        Parameters:
        oKey - key whose mapping is to be removed from the map
        Returns:
        true iff the Map changed as the result of this operation

      • addMapListener

        public void addMapListener​(MapListener listener)
        Add a standard map listener that will receive all events (inserts, updates, deletes) that occur against the map, with the key, old-value and new-value included. This has the same result as the following call: 
           addMapListener(listener, (Filter) null, false);
        Specified by:
        addMapListener in interface ObservableMap
        Parameters:
        listener - the MapEvent listener to add

      • removeMapListener

        public void removeMapListener​(MapListener listener)
        Remove a standard map listener that previously signed up for all events. This has the same result as the following call: 
           removeMapListener(listener, (Filter) null);
        Specified by:
        removeMapListener in interface ObservableMap
        Parameters:
        listener - the listener to remove

      • addMapListener

        public void addMapListener​(MapListener listener,
                           Object oKey,
                           boolean fLite)
        Add a map listener for a specific key.

        The listeners will receive MapEvent objects, but if fLite is passed as true, they might not contain the OldValue and NewValue properties.

        To unregister the MapListener, use the ObservableMap.removeMapListener(MapListener, Object) method.

        Specified by:
        addMapListener in interface ObservableMap
        Parameters:
        listener - the MapEvent listener to add
        oKey - the key that identifies the entry for which to raise events
        fLite - true to indicate that the MapEvent objects do not have to include the OldValue and NewValue property values in order to allow optimizations

      • removeMapListener

        public void removeMapListener​(MapListener listener,
                              Object oKey)
        Remove a map listener that previously signed up for events about a specific key.
        Specified by:
        removeMapListener in interface ObservableMap
        Parameters:
        listener - the listener to remove
        oKey - the key that identifies the entry for which to raise events

      • addMapListener

        public void addMapListener​(MapListener listener,
                           Filter filter,
                           boolean fLite)
        Add a map listener that receives events based on a filter evaluation.

        The listeners will receive MapEvent objects, but if fLite is passed as true, they might not contain the OldValue and NewValue properties.

        To unregister the MapListener, use the ObservableMap.removeMapListener(MapListener, Filter) method.

        Specified by:
        addMapListener in interface ObservableMap
        Parameters:
        listener - the MapEvent listener to add
        filter - a filter that will be passed MapEvent objects to select from; a MapEvent will be delivered to the listener only if the filter evaluates to true for that MapEvent (see MapEventFilter); null is equivalent to a filter that alway returns true
        fLite - true to indicate that the MapEvent objects do not have to include the OldValue and NewValue property values in order to allow optimizations

      • removeMapListener

        public void removeMapListener​(MapListener listener,
                              Filter filter)
        Remove a map listener that previously signed up for events based on a filter evaluation.
        Specified by:
        removeMapListener in interface ObservableMap
        Parameters:
        listener - the listener to remove
        filter - the filter that was passed into the corresponding addMapListener() call

        Returns:
        a description of this Map

      • getMapListenerSupport

        protected MapListenerSupport getMapListenerSupport()
        Accessor for the MapListenerSupport for sub-classes.
        Returns:
        the MapListenerSupport, or null if there are no listeners

      • hasListeners

        protected boolean hasListeners()
        Determine if this map has any listeners at all.
        Returns:
        true iff this ObservableMap has at least one MapListener

      • dispatchPendingEvent

        protected void dispatchPendingEvent​(Object oKey,
                                    int nId,

                                    boolean fSynthetic)
        Dispatch an event that has not yet occurred, allowing the cache to potentially avoid reading of the "original value" information.
        Parameters:
        oKey - the key which the event is related to
        nId - the event ID
        oNewValue - the new value
        fSynthetic - true if the event is synthetic

        protected void dispatchEvent​(CacheEvent evt)
        Dispatch the passed event.
        Parameters:
        evt - a CacheEvent object
