                      IgniteInClosure<GridNearTxPrepareResponse<K,V>> completeCb)

Parameters:

cctx - Context.

tx - Transaction.

nearMiniId - Near mini future id.

dhtVerMap - DHT versions map.

last - True if this is last prepare operation for node.

lastBackups - IDs of backup nodes receiving last prepare request during this prepare.

Method Detail

futureId

public IgniteUuid futureId()

Specified by:

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

Returns:

Unique identifier for this future.

nearMiniId

                     GridCacheMvccCandidate<K> owner)

Specified by:

onOwnerChanged in interface GridCacheMvccFuture<K,V,IgniteInternalTx<K,V>>

Parameters:

entry - Entry which received new owner.

owner - Owner.

Returns:

True if future cares about this entry.

trackable
