Constructor Detail

GridNearTxPrepareFuture

public GridNearTxPrepareFuture()

Empty constructor required for Externalizable.

GridNearTxPrepareFuture

public GridNearTxPrepareFuture(GridCacheSharedContext<K,V> cctx,
                       GridNearTxLocal<K,V> tx)

Parameters:

cctx - Context.

tx - Transaction.

Method Detail

futureId

public IgniteUuid futureId()

Specified by:

futureId in interface GridCacheFuture<IgniteInternalTx<K,V>>

Returns:

Unique identifier for this future.

version

public GridCacheVersion version()

Specified by:

version in interface GridCacheFuture<IgniteInternalTx<K,V>>

Returns:

Future version.

onOwnerChanged

public boolean onOwnerChanged(GridCacheEntryEx<K,V> entry,
                     GridCacheMvccCandidate<K> owner)

Specified by:

onOwnerChanged in interface GridCacheMvccFuture<K,V,IgniteInternalTx<K,V>>

Parameters:

entry - Entry which received new owner.

owner - Owner.

Returns:

True if future cares about this entry.

nodes

public Collection<? extends ClusterNode> nodes()

Specified by:

nodes in interface GridCacheFuture<IgniteInternalTx<K,V>>

Returns:

Involved nodes.

trackable

public boolean trackable()

Specified by:

trackable in interface GridCacheFuture<IgniteInternalTx<K,V>>

Returns:

True if future should be tracked.

markNotTrackable

public void markNotTrackable()

Marks this future as non-trackable.

Specified by:

markNotTrackable in interface GridCacheFuture<IgniteInternalTx<K,V>>

onNodeLeft

public boolean onNodeLeft(UUID nodeId)

Callback for when node left.

Specified by:

onNodeLeft in interface GridCacheFuture<IgniteInternalTx<K,V>>

Parameters:

nodeId - Left node ID.

Returns:

True if future cared about this node.

onResult

public void onResult(UUID nodeId,
            GridNearTxPrepareResponse<K,V> res)

Parameters:

nodeId - Sender.

res - Result.

onDone

public boolean onDone(IgniteInternalTx<K,V> 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<K,V>>

Parameters:

t - Optional result.

err - Optional error.

Returns:

True if result was set by this call.

prepare

public void prepare()

Waits for topology exchange future to be ready and then prepares user transaction.

toString

public String toString()

Overrides:

toString in class GridCompoundIdentityFuture<IgniteInternalTx<K,V>>
