cache.
|
| Insert(Object, Object, Int64) |
Associates the specified value with the specified key in this
cache.

Register the global back cache listener.
|
| RegisterListener(Object) |
Register the back cache listener for the specified key.
|
| RegisterListeners |
Register the back map listeners for the specified set of keys.
|
| Release |
Release the CompositeCache.
|
| Remove |
Remove the mapping for this key from this cache if present.
|
| RemoveKeyHolder |
Remove the key holder from the ThreadLocal object.
|
| ResetFrontMap |
Reset the front map.
|
| ResetHitStatistics |
Reset the cache statistics.
|
| ResetInvalidationStrategy |
Reset the "current invalidation strategy" flag.
|
| SetKeyHolder |
Set up a thread local Set to hold all the keys that might be evicted
from the front cache.
|
| ToString |
For debugging purposes, format the contents of the
CompositeCache in a human readable format.
(Overrides Object..::..ToString()()()().) |
| TryLock |
Lock the keys in the given set without blocking.
|
| UnregisterDeactivationListener |
Unregister back cache deactivation listener.
|
| UnregisterFrontListener |
Unregister the global front cache listener.
|
| UnregisterListener()()()() |
Unregister the global back cache listener.
|
| UnregisterListener(Object) |
Unregister the back cache listener for the specified key.
|
| UnregisterListeners |
Unregister the back cache listener for the specified keys.
Note: all the keys in the passed-in set must be locked and will be unlocked. |
| Validate |
Validate the front cache entry for the specified back cache
event.
|
Fields

different from the target strategy.
|
| m_strategyTarget |
The invalidation strategy that this cache is to use.
|
| s_tloKeys |
