org.xtreemfs.babudb.api.database.DatabaseRO.lookup()
Performs a lookup for a single key. The result object contains a byte array containing the value, or null if the key could not be found. @param indexId index id (0..NumIndices-1) @param key the key to look up @param context arbitrary context which is passed to the listener. @return a future as proxy for the request result.
