Method Detail

futureId

public IgniteUuid futureId()

Specified by:

futureId in interface GridCacheFuture<Boolean>

Returns:

Unique identifier for this future.

version

public GridCacheVersion version()

Specified by:

version in interface GridCacheFuture<Boolean>

Returns:

Future version.

nodes

public Collection<? extends ClusterNode> nodes()

Specified by:

nodes in interface GridCacheFuture<Boolean>

Returns:

Involved nodes.

onNodeLeft

public boolean onNodeLeft(UUID nodeId)

Callback for when node left.

Specified by:

onNodeLeft in interface GridCacheFuture<Boolean>

Parameters:

nodeId - Left node ID.

Returns:

True if future cared about this node.

trackable

public boolean trackable()

Specified by:

trackable in interface GridCacheFuture<Boolean>

Returns:

True if future should be tracked.

markNotTrackable

public void markNotTrackable()

Marks this future as non-trackable.

Specified by:

markNotTrackable in interface GridCacheFuture<Boolean>

onOwnerChanged

public boolean onOwnerChanged(GridCacheEntryEx entry,
                     GridCacheMvccCandidate owner)

Specified by:

onOwnerChanged in interface GridCacheMvccFuture<Boolean>

Parameters:

entry - Entry which received new owner.

owner - Owner.

Returns:

True if future cares about this entry.

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<Boolean>

Overrides:

cancel in class GridFutureAdapter<Boolean>

Returns:

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

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class GridFutureAdapter<Boolean>
