    ZMQ Constant Types

    ZMQ::SOCKET_PAIR

    Exclusive pair pattern

    ZMQ::SOCKET_PUB

    Publisher socket

    ZMQ::SOCKET_SUB

    Subscriber socket

    ZMQ::SOCKET_REQ

    Request socket

    ZMQ::SOCKET_REP

    Reply socket

    ZMQ::SOCKET_XREQ

    Alias for SOCKET_DEALER

    ZMQ::SOCKET_XREP

    Alias for SOCKET_ROUTER

    ZMQ::SOCKET_PUSH

    Pipeline upstream push socket

    ZMQ::SOCKET_PULL

    Pipeline downstream pull socket

    ZMQ::SOCKET_ROUTER

    Extended REP socket that can route replies to requesters

    ZMQ::SOCKET_DEALER

    Extended REQ socket that load balances to all connected peers

    ZMQ::SOCKET_XPUB

    Similar to SOCKET_PUB, except you can receive subscriptions as messages. The subscription message is 0 (unsubscribe) or 1 (subscribe) followed by the topic.

    ZMQ::SOCKET_XSUB

    Similar to SOCKET_SUB, except you can send subscriptions as messages. See SOCKET_XPUB for format.

    ZMQ::SOCKET_STREAM

    Used to send and receive TCP data from a non-ØMQ peer. Available if compiled against ZeroMQ 4.x or higher (Value: int).

    ZMQ::SOCKOPT_HWM

    The high water mark for inbound and outbound messages is a hard limit on the maximum number of outstanding messages ØMQ shall queue in memory for any single peer that the specified socket is communicating with. Setting this option on a socket will only affect connections made after the option has been set. On ZeroMQ 3.x this is a wrapper for setting both SNDHWM and RCVHWM. (Value: int).

    ZMQ::SOCKOPT_SNDHWM

    The ZMQ_SNDHWM option shall set the high water mark for outbound messages on the specified socket. Available if compiled against ZeroMQ 3.x or higher (Value: int).

    ZMQ::SOCKOPT_RCVHWM

    The SOCKOPT_RCVHWM option shall set the high water mark for inbound messages on the specified socket. Available if compiled against ZeroMQ 3.x or higher (Value: int).

    ZMQ::SOCKOPT_AFFINITY

    Set I/O thread affinity (Value: int)

    ZMQ::SOCKOPT_IDENTITY

    Set socket identity (Value: string)

    ZMQ::SOCKOPT_SUBSCRIBE

    Establish message filter. Valid for subscriber socket (Value: string)

    ZMQ::SOCKOPT_UNSUBSCRIBE

    Remove message filter. Valid for subscriber socket (Value: string)

    ZMQ::SOCKOPT_RATE

    Set rate for multicast sockets (pgm) (Value: int >= 0)

    ZMQ::SOCKOPT_RECOVERY_IVL

    Set multicast recovery interval (Value: int >= 0)

    ZMQ::SOCKOPT_RECONNECT_IVL
