Method Detail

init

public void init(@Nullable
                 @Nullable AffinityTopologyVersion topVer)

Initializes future.

Parameters:

topVer - Topology version.

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.

isMini

protected boolean isMini(IgniteInternalFuture<?> f)

Specified by:

isMini in class CacheDistributedGetFutureAdapter<K,V>

Parameters:

f - Future.

Returns:

True if mini-future.

map

protected void map(Collection<KeyCacheObject> keys,
                   Map<ClusterNode,LinkedHashMap<KeyCacheObject,Boolean>> mapped,
                   AffinityTopologyVersion topVer)

Specified by:

map in class CacheDistributedGetFutureAdapter<K,V>

Parameters:

keys - Keys.

mapped - Mappings to check for duplicates.

topVer - Topology version to map on.

toString

public String toString()

Overrides:
