/*!
|

|
|
Provides a @c Tape with a queue of upcoming pulses and an is-at-end flag.
|
||
|
|
|
||
|
|
If is-at-end is set then get_next_pulse() returns a second of silence and
|
||
|
|
is_at_end() returns true.
|
||
|
|
|
||
|
|
Otherwise get_next_pulse() returns something from the pulse queue if there is
|
||
|
|
anything there, and otherwise calls get_next_pulses(). get_next_pulses() is
|
||
|
|
virtual, giving subclasses a chance to provide the next batch of pulses.
