Constructor Detail

GridNearLockResponse

public GridNearLockResponse()

Empty constructor (required by Externalizable).

GridNearLockResponse

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

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.

clientRemapVer - True if client node should remap lock request. If compatibleRemapVer is true when first request is not remapped, but all subsequent will use remap version.

addDepInfo - Deployment info.

compatibleRemapVer - True if remap version is compatible with lock version.

Method Detail

clientRemapVersion

@Nullable
public @Nullable AffinityTopologyVersion clientRemapVersion()

Returns:

True if client node should remap lock request.

compatibleRemapVersion

public boolean compatibleRemapVersion()

Returns:

True is remap version is compatible with current topology version.

pending

public Collection<GridCacheVersion> pending()

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

Returns:

Pending versions.

pending

public void pending(Collection<GridCacheVersion> pending)

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

Parameters:

pending - Pending versions.

miniId

public int miniId()

Returns:

Mini future ID.

dhtVersion

public GridCacheVersion dhtVersion(int idx)

Parameters:

idx - Index.

Returns:

DHT version.

mappedVersion

public GridCacheVersion mappedVersion(int idx)

Returns DHT candidate version for acquired near lock on DHT node.

Parameters:

idx - Key index.

Returns:

DHT version.

filterResult

public boolean filterResult(int idx)

Gets filter evaluation result for fast-commit transaction.

Parameters:

idx - Result index.

Returns:

True if filter passed on primary node, false otherwise.

addValueBytes

public void addValueBytes(@Nullable
                          @Nullable CacheObject val,
