Constructor Detail

GridNearPessimisticTxPrepareFuture

public GridNearPessimisticTxPrepareFuture(GridCacheSharedContext cctx,
                                  GridNearTxLocal tx)

Parameters:

cctx - Context.

tx - Transaction.

Method Detail

ignoreFailure

protected boolean ignoreFailure(Throwable err)

Checks if this compound future should ignore this particular exception.

Overrides:

ignoreFailure in class GridCompoundFuture<GridNearTxPrepareResponse,IgniteInternalTx>

Parameters:

err - Exception to check.

Returns:

True if this error should be ignored.

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.

prepare

public void prepare()

Prepares transaction.

Specified by:

prepare in class GridNearTxPrepareFutureAdapter

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.

onDone

public boolean onDone(@Nullable
             IgniteInternalTx res,
             @Nullable
             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:

res - Optional result.

err - Optional error.

Returns:

True if result was set by this call.

toString

public String toString()

Overrides:
