Vordefinierte Konstanten

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: Integer).

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: Integer).

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: Integer).

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: Integer).

ZMQ::SOCKOPT_AFFINITY

Set I/O thread affinity (Value: Integer)

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: Integer >= 0)

ZMQ::SOCKOPT_RECOVERY_IVL

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

ZMQ::SOCKOPT_RECONNECT_IVL

Set the initial reconnection interval (Value: Integer >= 0)

ZMQ::SOCKOPT_RECONNECT_IVL_MAX

Set the max reconnection interval (Value: Integer >= 0)

ZMQ::SOCKOPT_MCAST_LOOP

Control multicast loopback (Value: Integer >= 0)

ZMQ::SOCKOPT_SNDBUF

Set kernel transmit buffer size (Value: Integer >= 0)

ZMQ::SOCKOPT_RCVBUF

Set kernel receive buffer size (Value: Integer >= 0)

ZMQ::SOCKOPT_RCVMORE

Receive multi-part messages (Value: Integer)

ZMQ::SOCKOPT_TYPE

Get the socket type. Valid for getSockOpt (Value: Integer)

ZMQ::SOCKOPT_LINGER

The linger value of the socket. Specifies how long the socket blocks trying flush messages after it has been closed (Value: Integer)

ZMQ::SOCKOPT_BACKLOG

The SOCKOPT_BACKLOG option shall set the maximum length of the queue of outstanding peer connections for the specified socket; this only applies to connection-oriented transports. (Value: Integer)

ZMQ::SOCKOPT_MAXMSGSIZE

Limits the maximum size of the inbound message. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_SNDTIMEO

Sets the timeout for send operation on the socket. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_RCVTIMEO

Sets the timeout for receive operation on the socket. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_IPV4ONLY

Disable IPV6 support if 1. Available if compiled against ZeroMQ 3.x (Value: Integer)

ZMQ::SOCKOPT_LAST_ENDPOINT

Retrieve the last connected endpoint - for use with * wildcard ports. Available if compiled against ZeroMQ 3.x or higher (Value: String)

ZMQ::SOCKOPT_TCP_KEEPALIVE_IDLE

Idle time for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_TCP_KEEPALIVE_CNT

Count time for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_TCP_KEEPALIVE_INTVL

Interval for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::SOCKOPT_DELAY_ATTACH_ON_CONNECT

Set a CIDR string to match against incoming TCP connections. Available if compiled against ZeroMQ 3.x or higher (Value: String)

ZMQ::SOCKOPT_TCP_ACCEPT_FILTER

Set a CIDR string to match against incoming TCP connections. Available if compiled against ZeroMQ 3.x or higher (Value: String)

ZMQ::SOCKOPT_XPUB_VERBOSE

Set the XPUB to receive an application message on each instance of a subscription. Available if compiled against ZeroMQ 3.x or higher (Value: String)

ZMQ::SOCKOPT_ROUTER_RAW

Sets the raw mode on the ROUTER, when set to 1. In raw mode when using tcp:// transport the socket will read and write without ZeroMQ framing. Available if compiled against ZeroMQ 4.0 or higher (Value: String)

ZMQ::SOCKOPT_IPV6

Enable IPV6. Available if compiled against ZeroMQ 4.0 or higher (Value: String)

ZMQ::CTXOPT_MAX_SOCKETS

The socket limit for this context. Available if compiled against ZeroMQ 3.x or higher (Value: Integer)

ZMQ::POLL_IN

Poll for incoming data

ZMQ::POLL_OUT

Poll for outgoing data

ZMQ::MODE_NOBLOCK

Non-blocking operation. Deprecated, use ZMQ::MODE_DONTWAIT instead

ZMQ::MODE_DONTWAIT

Non-blocking operation

ZMQ::MODE_SNDMORE

Send multi-part message

ZMQ::DEVICE_FORWARDER

Forwarder device

ZMQ::DEVICE_QUEUE

Queue device

ZMQ::DEVICE_STREAMER

Streamer device

ZMQ::ERR_INTERNAL

ZMQ extension internal error

ZMQ::ERR_EAGAIN

Implies that the operation would block when ZMQ::MODE_DONTWAIT is used

ZMQ::ERR_ENOTSUP

The operation is not supported by the socket type

ZMQ::ERR_EFSM

The operation can not be executed because the socket is not in correct state

ZMQ::ERR_ETERM

The context has been terminated
