Constructor Summary | |
---|---|
AbstractSerializationCache(BinaryStore store)
Construct a serialization cache on top of a BinaryStore. |
|
AbstractSerializationCache(BinaryStore store,
boolean fBinaryMap)
Construct a serialization cache on top of a BinaryStore, optionally storing only Binary keys and values. |
|
AbstractSerializationCache(BinaryStore store,
ClassLoader loader)
Construct a serialization cache on top of a BinaryStore, using the passed ClassLoader for deserialization. |
Method Summary | |
---|---|
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. |
void |
addMapListener(MapListener listener,
Filter filter,
boolean fLite)
Add a map listener that receives events based on a filter evaluation. |
void |
addMapListener(MapListener listener,
Object oKey,
boolean fLite)
Add a map listener for a specific key. |
void |
clear()
Clear all key/value mappings. |
protected void |
dispatchEvent(CacheEvent evt)
Dispatch the passed event. |
protected void |
dispatchPendingEvent(Object oKey,
int nId,
Object oNewValue,
boolean fSynthetic)
Dispatch an event that has not yet occurred, allowing the cache to potentially avoid reading of the "original value" information. |
abstract void |
evict()
Flush items that have expired. |
protected String |
getDescription()
Assemble a human-readable description. |
protected MapListenerSupport |
getMapListenerSupport()
Accessor for the MapListenerSupport for sub-classes. |
protected boolean |
hasListeners()
Determine if this map has any listeners at all. |
Object |
put(Object oKey,
Object oValue)
Associates the specified value with the specified key in this map. |
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(java.lang.Object, java.lang.Object)
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. |
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. |
protected boolean |
removeBlind(Object oKey)
Removes the mapping for this key from this map if present. This method exists to allow sub-classes to optmiize remove functionalitly for situations in which the original value is not required. |
void |
removeMapListener(MapListener listener)
Remove a standard map listener that previously signed up for all events. |
void |
removeMapListener(MapListener listener,
Filter filter)
Remove a map listener that previously signed up for events based on a filter evaluation. |
void |
removeMapListener(MapListener listener,
Object oKey)
Remove a map listener that previously signed up for events about a specific key. |
