msgId - Message ID.

reader - Reader.

keys - Keys.

readThrough - Read through flag.

reload - Reload flag.

tx - Transaction.

topVer - Topology version.

subjId - Subject ID.

taskNameHash - Task name hash code.

expiryPlc - Expiry policy.

skipVals - Skip values flag.

Method Detail

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<Collection<GridCacheEntryInfo>>

Returns:

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

futureId

public IgniteUuid futureId()

Returns:

Future ID.

version

public GridCacheVersion version()

Returns:

Future version.

onDone

public boolean onDone(Collection<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<Collection<GridCacheEntryInfo>>

Parameters:

res - Optional result.

err - Optional error.

Returns:

True if result was set by this call.
