"- get_next_state() returns a new DFA object, which
is in the next state. If there is no next state, it
returns undef."
Examples:
if ( $state1->get_next_state() )
{
$state1->next_state;
}
else
{
die "no next state";
}
if ( $state2 = $state1->get_next_state() )
{
$state1 = $state2;
}
else
{
die "no next state";
}
