$on_new_socket = null)
Constructs a ZMQSocket object. persistent_id parameter can be used to allocated a persistent socket. A persistent socket has to be allocated from a persistent context and it stays connected over multiple requests. The persistent_id parameter can be used to recall the same socket over multiple requests. The
on_new_socket is called only when a new underlying socket structure is created.
Параметри
context-
ZMQContext object.
type-
The socket type. See
ZMQ::SOCKET_*constants. persistent_id-

persistent_idis specified the socket will be persisted over multiple requests. Ifcontextis not persistent the socket falls back to non-persistent mode. on_new_socket-
