NAME
Message::Passing::ZeroMQ::Role::HasASocket - Role for instances which have a ZeroMQ socket.
ATTRIBUTES
socket_bind
Bind a server to an address.
For example tcp://*:5222 to make a server listening on a port on all of the host's addresses, or tcp://127.0.0.1:5222 to bind the socket to a specific IP on the host.
connect
Connect to a server. For example tcp://127.0.0.1:5222.
This option is mutually exclusive with socket_bind, as sockets can connect in one direction only.
socket_type
The connection direction can be either the same as, or the opposite of the message flow direction.
The currently supported socket types are:
PUB
This socket publishes messages to zero or more subscribers.
All subscribers get a copy of each message.
SUB
The pair of PUB, receives broadcast messages.
PUSH
This socket type distributes messages in a round-robin fashion between subscribers. Therefore N subscribers will see 1/N of the message flow.
PULL
The pair of PUSH, receives a proportion of messages distributed.
linger
Bool indicating the value of the ZMQ_LINGER options.
Defaults to 0 meaning sockets are lossy, but will not block.
linger off (default)
Sending messages will be buffered on the client side up to the set buffer for this connection. Further messages will be dropped until the buffer starts to empty.
Receiving messages will be buffered by ZeroMQ for you until you're ready to receive them, after which they will be discarded.
linger off
Sending messages will be be buffered on the client side up to the set buffer for this connection. If this buffer fills, then ZeroMQ will block the program which was trying to send the message. If the client quits before all messages were sent, ZeroMQ will block exit until they have been sent.
METHODS
setsockopt
For wrapping by sub-classes to set options after the socket is created.
