Constructor Detail

GridDhtColocatedLockFuture

public GridDhtColocatedLockFuture(GridCacheContext<?,?> cctx,
                          Collection<KeyCacheObject> keys,
                          @Nullable
                          GridNearTxLocal tx,
                          boolean read,
                          boolean retval,
                          long timeout,
                          long accessTtl,
                          CacheEntryPredicate[] filter,
                          boolean skipStore,
                          boolean keepBinary)

Parameters:

cctx - Registry.

keys - Keys to lock.

tx - Transaction.

read - Read flag.

retval - Flag to return value or not.

timeout - Lock acquisition timeout.

accessTtl - TTL for read operation.

filter - Filter.

skipStore - Skip store flag.

Method Detail

version

public GridCacheVersion version()

Specified by:

version in interface GridCacheMvccFuture<Boolean>

Returns:

Future version.

onOwnerChanged

public boolean onOwnerChanged(GridCacheEntryEx entry,
                     GridCacheMvccCandidate owner)

Specified by:

onOwnerChanged in interface GridCacheMvccFuture<Boolean>

Parameters:

entry - Entry which received new owner.

owner - Owner.

Returns:

True if future cares about this entry.

futureId

public IgniteUuid futureId()

Specified by:

futureId in interface GridCacheFuture<Boolean>

Returns:

Future ID.

trackable

public boolean trackable()

Specified by:

trackable in interface GridCacheFuture<Boolean>

Returns:

True if future should be tracked.

markNotTrackable

public void markNotTrackable()

Marks this future as non-trackable.

Specified by:

markNotTrackable in interface GridCacheFuture<Boolean>

complete

public void complete(boolean success)

Parameters:

success - Success flag.

onNodeLeft

public boolean onNodeLeft(UUID nodeId)

Description copied from interface: GridCacheFuture

Callback for when node left.

Specified by:

onNodeLeft in interface GridCacheFuture<Boolean>

Parameters:

nodeId - Left node ID

Returns:

True if node was in the list.

requestedKeys

public Set<IgniteTxKey> requestedKeys()

Returns:

Keys for which locks requested from remote nodes but response isn't received.

cancel

public boolean cancel()

Default no-op implementation that always returns false. Futures that do support cancellation should override this method and call GridFutureAdapter.onCancelled() callback explicitly if cancellation indeed did happen.

Specified by:

cancel in interface IgniteInternalFuture<Boolean>

Overrides:

cancel in class GridCompoundFuture<Boolean,Boolean>

Returns:

True if future was canceled (i.e. was not finished prior to this call).

onDone

public boolean onDone(Boolean success,
             Throwable err)

Callback to notify that future is finished. Note that if non-null exception is passed in the result value will be ignored.

Overrides:

onDone in class GridFutureAdapter<Boolean>

Parameters:

success - Optional result.

err - Optional error.

Returns:

True if result was set by this call.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class GridCompoundIdentityFuture<Boolean>
