.. class:: CallArgsInfo
Represent the "signature" or protocol of a listener in the context of
topics.
.. method:: __init__(self, func, firstArgIdx)
Inputs:
- Args and defaultVals are the complete set of arguments and
default values as obtained form inspect.getargspec();
- The firstArgIdx points to the first item in
args that is of use, so it is typically 0 if listener is a function,
and 1 if listener is a method.
- The acceptsAllKwargs should be true
if the listener has **kwargs in its protocol.
After construction,
- self.allParams will contain the subset of 'args' without first
firstArgIdx items,
- self.numRequired will indicate number of required arguments
(ie self.allParams[:self.numRequired] are the required args names);
- self.acceptsAllKwargs = acceptsAllKwargs
- self.autoTopicArgName will be the name of argument
in which to put the topic object for which pubsub message is
sent, or None. This is identified by the argument that has a
default value of AUTO_TOPIC.
For instance, listener(self, arg1, arg2=AUTO_TOPIC, arg3=None) will
have self.allParams = (arg1, arg2, arg3), self.numRequired=1, and
self.autoTopicArgName = 'arg2', whereas
listener(self, arg1, arg3=None) will have
self.allParams = (arg1, arg3), self.numRequired=1, and
self.autoTopicArgName = None.
.. method:: getAllArgs(self)
.. method:: getOptionalArgs(self)
.. method:: getRequiredArgs(self)
Return a tuple of names indicating which call arguments
are required to be present when pub.sendMessage(...) is called.
