public GridNearGetRequest()

Empty constructor required for Externalizable.

GridNearGetRequest

public GridNearGetRequest(int cacheId,
                  IgniteUuid futId,
                  IgniteUuid miniId,
                  GridCacheVersion ver,
                  LinkedHashMap<K,Boolean> keys,
                  boolean readThrough,
                  boolean reload,
                  long topVer,
                  UUID subjId,
                  int taskNameHash,
                  long accessTtl,
                  boolean skipVals)

Parameters:

cacheId - Cache ID.

futId - Future ID.

miniId - Sub ID.

ver - Version.
