Constructor Detail

GridDhtAssignmentFetchFuture

public GridDhtAssignmentFetchFuture(GridCacheContext<K,V> ctx,
                            long topVer,
                            Collection<ClusterNode> availableNodes)

Parameters:

ctx - Cache context.

availableNodes - Available nodes.

Method Detail

init

public void init()

Initializes fetch future.

onResponse

public void onResponse(ClusterNode node,
              GridDhtAffinityAssignmentResponse<K,V> res)

Parameters:

node - Node.

res - Reponse.

onNodeLeft

public void onNodeLeft(UUID leftNodeId)

Parameters:

leftNodeId - Left node ID.

onDone

public boolean onDone(@Nullable
             List<List<ClusterNode>> res,
             @Nullable
             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<List<List<ClusterNode>>>

Parameters:

res - Optional result.

err - Optional error.

Returns:

True if result was set by this call.
