Constructor Detail

SnapshotFinishedFutureTask

public SnapshotFinishedFutureTask(IgniteCheckedException e)

Parameters:

e - Finished snapshot task future with particular exception.

Method Detail

start

public boolean start()

Initiates snapshot task.

Returns:

true if task started by this call.

acceptException

public void acceptException(Throwable th)

Parameters:

th - An exception which occurred during snapshot processing.

snapshotName

public String snapshotName()

Returns:

Snapshot name.

sourceNodeId

public UUID sourceNodeId()

Returns:

Node id which triggers this operation.

requestId

public UUID requestId()

Returns:

Snapshot operation request ID.

affectedCacheGroups

public Set<Integer> affectedCacheGroups()

Returns:

Set of cache groups included into snapshot operation.

cancel

public boolean cancel()

Default no-op implementation that always returns false. Futures that do support cancellation should override this method and call GridFutureAdapter.onCancelled() callback explicitly if cancellation indeed did happen.

Specified by:

cancel in interface IgniteInternalFuture<T>

Overrides:

cancel in class GridFutureAdapter<T>

Returns:

True if future was canceled (i.e. was not finished prior to this call).

toString

public String toString()

Overrides:

toString in class GridFutureAdapter<T>
