Class Bytes

  • public class Bytes
extends BSON
    Class that hold definitions of the wire protocol

    • Field Detail

      • ORDER

        public static final java.nio.ByteOrder ORDER
        Little-endian

      • QUERYOPTION_TAILABLE

        public static final int QUERYOPTION_TAILABLE
        Tailable means cursor is not closed when the last data is retrieved. Rather, the cursor marks the final object's position. You can resume using the cursor later, from where it was located, if more data were received. Like any "latent cursor", the cursor may become invalid at some point (CursorNotFound) - for example if the final object it references were deleted.

        Constant Field Values

      • QUERYOPTION_SLAVEOK

        public static final int QUERYOPTION_SLAVEOK
        When turned on, read queries will be directed to slave servers instead of the primary server.

        Constant Field Values

      • QUERYOPTION_OPLOGREPLAY

        public static final int QUERYOPTION_OPLOGREPLAY
        Internal replication use only - driver should not set
        See Also:
        Constant Field Values

      • QUERYOPTION_NOTIMEOUT

        public static final int QUERYOPTION_NOTIMEOUT
        The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that.
        See Also:
        Constant Field Values

      • QUERYOPTION_AWAITDATA

        public static final int QUERYOPTION_AWAITDATA
        Use with TailableCursor. If we are at the end of the data, block for a while rather than returning no data. After a timeout period, we do return as normal.

        Constant Field Values

      • QUERYOPTION_EXHAUST

        public static final int QUERYOPTION_EXHAUST
        Stream the data down full blast in multiple "more" packages, on the assumption that the client will fully read all data queried. Faster when you are pulling a lot of data and know you want to pull it all down. Note: the client is not allowed to not read all the data unless it closes the connection.

        Constant Field Values

      • QUERYOPTION_PARTIAL

        public static final int QUERYOPTION_PARTIAL
        Use with sharding (mongos). Allows partial results from a sharded system if any shards are down/missing from the cluster. If not used an error will be returned from the mongos server.

        Constant Field Values

      • RESULTFLAG_CURSORNOTFOUND

        public static final int RESULTFLAG_CURSORNOTFOUND
        Set when getMore is called but the cursor id is not valid at the server. Returned with zero results.
        See Also:
        Constant Field Values

      • RESULTFLAG_ERRSET

        public static final int RESULTFLAG_ERRSET
        Set when query failed. Results consist of one document containing an "$err" field describing the failure.
        See Also:
        Constant Field Values

      • RESULTFLAG_SHARDCONFIGSTALE

        public static final int RESULTFLAG_SHARDCONFIGSTALE
        Drivers should ignore this. Only mongos will ever see this set, in which case, it needs to update config from the server.
        See Also:
        Constant Field Values

      • RESULTFLAG_AWAITCAPABLE

        public static final int RESULTFLAG_AWAITCAPABLE
        Set when the server supports the AwaitData Query option. If it doesn't, a client should sleep a little between getMore's of a Tailable cursor. Mongod version 1.6 supports AwaitData and thus always sets AwaitCapable.

        public static byte getType​(java.lang.Object object)
