                 @Nullable
                 UUID subjId)

Parameters:

cctx - Context.

keys - Keys.

reload - Reload flag.

forcePrimary - If true get will be performed on primary node even if called on backup node.

tx - Transaction.

filters - Filters.

Method Detail

init

public void init()

Initializes future.

trackable

public boolean trackable()

Specified by:

trackable in interface GridCacheFuture<Map<K,V>>

Returns:

True if future should be tracked.

markNotTrackable

public void markNotTrackable()

Marks this future as non-trackable.

Specified by:

markNotTrackable in interface GridCacheFuture<Map<K,V>>

futureId

public GridUuid futureId()

Specified by:

futureId in interface GridCacheFuture<Map<K,V>>

Returns:

Unique identifier for this future.

version

public GridCacheVersion version()

Specified by:

version in interface GridCacheFuture<Map<K,V>>

Returns:

Future version.

nodes

public Collection<? extends GridNode> nodes()

Specified by:

nodes in interface GridCacheFuture<Map<K,V>>

Returns:

Involved nodes.

onNodeLeft

public boolean onNodeLeft(UUID nodeId)

Callback for when node left.

Specified by:

onNodeLeft in interface GridCacheFuture<Map<K,V>>

Parameters:

nodeId - Left node ID.

Returns:

True if future cared about this node.

onDone

public boolean onDone(Map<K,V> 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<Map<K,V>>

Parameters:

res - Optional result.

err - Optional error.

Returns:

True if result was set by this call.
