The building blocks of a model are its classes and relations.
The building blocks of the execution of a model are instances of these
classes and relations, which are created during execution.
The animator automatically names these instances.
Naming class instances
During execution, the instances of a class A are
referred to as A[0], A[1], A[2],
and so on. The name A[0] is given to the first instance
of class A, the name A[1] to the
second, and so on.
Component instance names
Instances of a component use the following naming scheme,
where the composite is the whole and the component is the part:
Special object names
Besides classes and instances, the animator tracks a few
other special objects such as breakpoints, call stacks, and event
queues. You can reference all these special objects from the command
prompt using tracer commands.
