Constructor Detail

GridNearOptimisticTxPrepareFuture

public GridNearOptimisticTxPrepareFuture(GridCacheSharedContext cctx,
                                 GridNearTxLocal tx)

Parameters:

cctx - Context.

tx - Transaction.

Method Detail

onOwnerChanged

public boolean onOwnerChanged(GridCacheEntryEx entry,
                     GridCacheMvccCandidate owner)

Parameters:

entry - Entry which received new owner.

owner - Owner.

Returns:

True if future cares about this entry.

onNodeLeft

public boolean onNodeLeft(UUID nodeId)

Callback for when node left.

Parameters:

nodeId - Left node ID.

Returns:

True if future cared about this node.

onResult

public void onResult(UUID nodeId,
            GridNearTxPrepareResponse res)

Specified by:

onResult in class GridNearTxPrepareFutureAdapter

Parameters:

nodeId - Sender.

res - Result.

requestedKeys

public Set<IgniteTxKey> requestedKeys()

Returns:

Keys for which MiniFuture isn't completed.

onDone

public boolean onDone(IgniteInternalTx t,
             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<IgniteInternalTx>

Parameters:

t - Optional result.

err - Optional error.

Returns:

True if result was set by this call.

prepare0

protected void prepare0(boolean remap,
            boolean topLocked)

Initializes future.

Specified by:

prepare0 in class GridNearOptimisticTxPrepareFutureAdapter

Parameters:

remap - Remap flag.

topLocked - True if thread already acquired lock preventing topology change.

toString

public String toString()

Overrides:

toString in class GridCompoundFuture<GridNearTxPrepareResponse,IgniteInternalTx>
