protected boolean isNearLocallyMapped(GridCacheEntryEx e,
                                      AffinityTopologyVersion topVer)

Parameters:

e - Transaction entry.

topVer - Topology version.

Returns:

True if entry is locally mapped as a primary or back up node.

evictNearEntry

protected boolean evictNearEntry(GridCacheEntryEx e,
                                 GridCacheVersion obsoleteVer,

topVer - Topology version.

Returns:

True if attempt was made to evict the entry.

unlockAll

public void unlockAll(Collection<? extends K> keys)

Unlocks given keys only if current thread owns the locks. Only the keys that have been locked by calling thread and pass through the filter (if any) will be unlocked. If none of the key locks is owned by current thread, then this method will do nothing.

Transactions

Locks are not transactional and should not be used from within transactions. If you do need explicit locking within transaction, then you should use TransactionConcurrency.PESSIMISTIC concurrency control for transaction which will acquire explicit locks for relevant cache operations.

Parameters:

keys - Keys to unlock.

removeLocks

public void removeLocks(GridCacheVersion ver,
                        Collection<KeyCacheObject> keys)

Removes locks regardless of whether they are owned or not for given version and keys.

Parameters:

ver - Lock version.

keys - Keys.

onDeferredDelete

public void onDeferredDelete(GridCacheEntryEx entry,
                             GridCacheVersion ver)

Specified by:

onDeferredDelete in class GridCacheAdapter<K,V>

Parameters:

entry - Entry.

ver - Version.

toString

public String toString()

Overrides:

toString in class GridNearCacheAdapter<K,V>
