An active object system is a transition-based object-oriented system suitable
for the design of various concurrent systems. An AOS consists of a collection
of interacting objects, where the behavior of each object is determined by the
transition statements provided in the class of that object. A transition statement
is a condition-action pair, an equational assignment statement, or an event routine.
The transition statements provided for each object can access, besides the state
of that object, the states of the other objects known to it through its interface
variables. Interface variables are bound to objects when objects are instantiated
so that desired connections among objects are established. The major benefit of
the AOS approach is that an active system can be hierarchically composed from
its active software components as if it were a hardware system. An AOS provides
better encapsulation and more flexible communication protocols than ordinary
object oriented systems, since control within an AOS is localized. / Graduation date: 1992
