GridNearLockResponse

public GridNearLockResponse(int cacheId,
                    GridCacheVersion lockVer,
                    IgniteUuid futId,
                    IgniteUuid miniId,
                    boolean filterRes,
                    int cnt,
                    Throwable err)

Parameters:

cacheId - Cache ID.

lockVer - Lock ID.

futId - Future ID.

miniId - Mini future ID.

filterRes - True if need to allocate array for filter evaluation results.

cnt - Count.

err - Error.

Method Detail

pending

public Collection<GridCacheVersion> pending()

Gets pending versions that are less than GridDistributedBaseMessage.version().

Returns:

DHT version.

filterResult

public boolean filterResult(int idx)

Gets filter evaluation result for fast-commit transaction.

Parameters:

idx - Result index.

Returns:
