Inherits
val mutable selected : (child * Source.source) option
val mutable to_finish : Source.source list
We have to explictly manage our children as they are dynamically created
by application of the transition functions. In particular we need a list
of all children that have output data in the current round.
val mutable need_eot : bool
Indicates that the former child was left without having finished its
track, in which case the switch will artifically produce an EOT.
method private virtual select : child option
The selection method should return None or Some c,
where c is a ready child.
val mutable cached_selected : child option option
Don't call #select directly but use #cached_select
to ensure consistency during one time tick between #is_ready and
#get_frame.
