Method Detail

getSegments

public org.infinispan.commons.util.IntSet getSegments()

Returns a copy of segments currently tied to this task

Returns:

copy of segments

getUnfinishedSegments

public org.infinispan.commons.util.IntSet getUnfinishedSegments()

Returns a copy of the unfinished segments

Returns:

getSource

public Address getSource()

requestSegments

public CompletableFuture<Void> requestSegments()

Send START_STATE_TRANSFER request to source node.

Returns:

a CompletableFuture that completes when the transfer is done.

requestKeys

public CompletableFuture<Void> requestKeys()

cancelSegments

public void cancelSegments(org.infinispan.commons.util.IntSet cancelledSegments)

Cancels a set of segments and marks them as finished. If all segments are cancelled then the whole task is cancelled, as if cancel() was called.

Parameters:

cancelledSegments - the segments to be cancelled

cancel

public void cancel()

Cancels all the segments and marks them as finished, sends a cancel command, then completes the task.

isCancelled

public boolean isCancelled()

onStateReceived

public void onStateReceived(int segmentId,
                            boolean isLastChunk)

isCompletedSuccessfully

public boolean isCompletedSuccessfully()

terminate

public void terminate()

Terminate abruptly regardless if the segments were received or not. This is used when the source node is no longer alive.

toString

public String toString()

Overrides:
