S ) r a� Frame(data=None, track=False, copy=None, copy_threshold=zmq.COPY_THRESHOLD)
A zmq message Frame class for non-copy send/recvs.
This class is only needed if you want to do non-copying send and recvs.
When you pass a string to this class, like ``Frame(s)``, the
ref-count of `s` is increased by two: once because the Frame saves `s` as
an instance attribute and another because a ZMQ message is created that
points to the buffer of `s`. This second ref-count increase makes sure
that `s` lives until all messages that use it have been sent. Once 0MQ
sends all the messages and it doesn't need the buffer of s, 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.
