Inheritance diagram for IPython.parallel.controller.heartmonitor:
A multi-heart Heartbeat system using PUB and XREP sockets. pings are sent out on the PUB, and hearts are tracked based on their XREQ identities.
Authors:
Bases: object
A basic heart object for responding to a HeartMonitor. This is a simple wrapper with defaults for the most common Device model for responding to heartbeats.
It simply builds a threadsafe zmq.FORWARDER Device, defaulting to using SUB/XREQ for in/out.
You can specify the XREQ’s IDENTITY via the optional heart_id argument.
Bases: IPython.config.configurable.LoggingConfigurable
A basic HeartMonitor class pingstream: a PUB stream pongstream: an XREP stream period: the period of the heartbeat in milliseconds

This method is just like the trait_names() method, but is unbound.

This method is just like the traits() method, but is unbound.
The TraitTypes returned don’t know anything about the values that the various HasTrait’s instances are holding.
This follows the same algorithm as traits does and does not allow for any simple way of specifying merely that a metadata name exists, but has any value. This is because get_metadata returns None if a metadata key doesn’t exist.
A trait whose value must be an instance of a specified class.
The value can also be an instance of a subclass of the specified class.

Setup a handler to be called when a trait changes.
This is used to setup dynamic notifications of trait changes.
Static handlers can be created by creating methods on a HasTraits subclass with the naming convention ‘_[traitname]_changed’. Thus, to create static handler for the trait ‘a’, create the method _a_changed(self, name, old, new) (fewer arguments can be used, see below).
Parameters : | handler : callable
name : list, str, None
remove : bool

Longs that are unnecessary (<= sys.maxint) are cast to ints.
