Constructor Detail

GridNearLockResponse

public GridNearLockResponse()

Empty constructor (required by Externalizable).

GridNearLockResponse

public GridNearLockResponse(GridCacheVersion lockVer,
                    GridUuid futId,
                    GridUuid miniId,
                    boolean filterRes,

                    Throwable err)

Parameters:

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:
