"Amalgamating Sessions and Methods in Object Oriented Languages"

Prof. M. Dezani
University of Turin

We suggest an amalgamation of communication based programming (centred
on sessions) and object oriented programming, whereby sessions between
concurrent threads are amalgamated with methods. In our proposal
threads consist of the execution of session bodies on objects and
communicate with each other through asynchronously sending/receiving
objects on channels.  The choice on how to respond to a session
request is based on the name of the request and the class of the
object receiving the request, the choice on how to continue a session
is made on the basis of the class of the object
sent/received. Sessions can be delegated to other sessions, although
session themselves are not first class objects.
