A ``zmq.Frame`` wraps an underlying ``zmq_msg_t``. Message *properties* can be accessed by treating a Frame like a dictionary (``frame["User-Id"]``). .. versionadded:: 14.4, libzmq 4 Frames created by ``recv(copy=False)`` can be used to access message properties and attributes, such as the CURVE User-Id. For example:: frames = socket.recv_multipart(copy=False) user_id = frames[0]["User-Id"] This class is used if you want to do non-copying send and recvs. When you pass a chunk of bytes to this class, e.g. ``Frame(buf)``, the ref-count of `buf` is increased by two: once because the Frame saves `buf` as an instance attribute and another because a ZMQ message is created that points to the buffer of `buf`. This second ref-count increase makes sure that `buf` lives until all messages that use it have been sent. Once 0MQ sends all the messages and it doesn't need the buffer of ``buf``, 0MQ will call ``Py_DECREF(s)``. Parameters ---------- data : object, optional any object that provides the buffer interface will be used to construct the 0MQ message data. track : bool [default: False] whether a MessageTracker_ should be created to track this object. Tracking a message has a cost at creation, because it creates a threadsafe Event object. copy : bool [default: use copy_threshold] Whether to create a copy of the data to pass to libzmq or share the memory with libzmq. If unspecified, copy_threshold is used. copy_threshold: int [default: zmq.COPY_THRESHOLD] If copy is unspecified, messages smaller than this many bytes will be copied and messages larger than this will be shared with libzmq. c,||S)N)get)selfkeys r __getitem__zFrame.__getitem__Csxx}}rcLtdd|dS)zThe RADIO-DISH group of the message.
