Constructor and Description
GridDhtGetSingleFuture(GridCacheContext<K,V> cctx, long msgId, UUID reader, KeyCacheObject key, boolean addRdr, boolean readThrough, @NotNull AffinityTopologyVersion topVer, @Nullable UUID subjId, int taskNameHash, @Nullable IgniteCacheExpiryPolicy expiryPlc, boolean skipVals, boolean recovery, @Nullable String txLbl, @Nullable MvccSnapshot mvccSnapshot)

Method Summary

Modifier and Type	Method and Description
IgniteUuid	futureId()
Collection<Integer>	invalidPartitions() Node that future should be able to provide keys to retry before it completes, so it's not necessary to wait till future is done to get retry keys.
boolean	onDone(GridCacheEntryInfo res, Throwable err) Callback to notify that future is finished.
GridCacheVersion	version()

Method Detail

futureId

public IgniteUuid futureId()

Returns:

Future ID.

version

public GridCacheVersion version()

Returns:

Future version.

onDone

public boolean onDone(GridCacheEntryInfo res,
                      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<GridCacheEntryInfo>

Parameters:

res - Optional result.

err - Optional error.

Returns:

True if result was set by this call.

invalidPartitions

public Collection<Integer> invalidPartitions()

Node that future should be able to provide keys to retry before it completes, so it's not necessary to wait till future is done to get retry keys.

Specified by:

invalidPartitions in interface GridDhtFuture<GridCacheEntryInfo>

Returns:

Keys to retry because this node is no longer a primary or backup.
