                              boolean keepCacheObjects)

Parameters:

cctx - Context.

key - Key.

topVer - Topology version.

readThrough - Read through flag.

forcePrimary - If true then will force network trip to primary node even if called on backup node.

subjId - Subject ID.

taskName - Task name.

deserializeBinary - Deserialize binary flag.

expiryPlc - Expiry policy.

skipVals - Skip values flag.

canRemap - Flag indicating whether future can be remapped on a newer topology version.

needVer - If true returns values as tuples containing value and version.

keepCacheObjects - Keep cache objects flag.

Method Detail

init

            GridNearSingleGetResponse res)

Parameters:

nodeId - Node ID.

res - Result.

onResult

public void onResult(UUID nodeId,
            GridNearGetResponse res)

Specified by:
