Simple switching
(-->) :: Monad m => Wire s e m a b -> Wire s e m a b -> Wire s e m a bSource
Acts like the first wire until it inhibits, then switches to the second wire. Infixr 1.
- Depends: like current wire.
- Inhibits: after switching like the second wire.
- Switch: now.
Context switching
:: (Monad m, Ord k) | |
=> k | Initial mode. |
-> (k -> Wire s e m a b) | Select wire for given mode. |
-> Wire s e m (a, Event k) b |
Route the left input signal based on the current mode. The right input signal can be used to change the current mode. When switching away from a mode and then switching back to it, it will be resumed. Freezes time during inactivity.
- Complexity: O(n * log n) space, O(log n) lookup time on switch wrt number of started, inactive modes.
- Depends: like currently active wire (left), now (right).
- Inhibits: when active wire inhibits.
- Switch: now on mode change.
Event-based switching
Intrinsic
switch :: (Monad m, Monoid s) => Wire s e m a (b, Event (Wire s e m a b)) -> Wire s e m a bSource
Intrinsic switch: Start with the given wire. As soon as its event occurs, switch to the wire in the event's value.
- Inhibits: like argument wire until switch, then like the new wire.
- Switch: once, now, restart state.
dSwitch :: Monad m => Wire s e m a (b, Event (Wire s e m a b)) -> Wire s e m a bSource
Intrinsic switch: Delayed version of switch
.
- Inhibits: like argument wire until switch, then like the new wire.
- Switch: once, after now, restart state.
Intrinsic continuable
kSwitch :: (Monad m, Monoid s) => Wire s e m a b -> Wire s e m (a, b) (Event (Wire s e m a b -> Wire s e m a b)) -> Wire s e m a bSource
Intrinsic continuable switch: kSwitch w1 w2
starts with w1
.
Its signal is received by w2
, which may choose to switch to a new
wire. Passes the wire we are switching away from to the new wire,
such that it may be reused in it.
- Inhibits: like the first argument wire, like the new wire after switch. Inhibition of the second argument wire is ignored.
- Switch: once, now, restart state.
dkSwitch :: Monad m => Wire s e m a b -> Wire s e m (a, b) (Event (Wire s e m a b -> Wire s e m a b)) -> Wire s e m a bSource
Intrinsic continuable switch: Delayed version of kSwitch
.
- Inhibits: like the first argument wire, like the new wire after switch. Inhibition of the second argument wire is ignored.
- Switch: once, after now, restart state.
Extrinsic
rSwitch :: Monad m => Wire s e m a b -> Wire s e m (a, Event (Wire s e m a b)) bSource
Extrinsic switch: Start with the given wire. Each time the input event occurs, switch to the wire it carries.
- Inhibits: like the current wire.
- Switch: recurrent, now, restart state.
drSwitch :: Monad m => Wire s e m a b -> Wire s e m (a, Event (Wire s e m a b)) bSource
Extrinsic switch: Delayed version of rSwitch
.
- Inhibits: like the current wire.
- Switch: recurrent, after now, restart state.
Extrinsic continuable
krSwitch :: Monad m => Wire s e m a b -> Wire s e m (a, Event (Wire s e m a b -> Wire s e m a b)) bSource
Extrinsic continuable switch. This switch works like rSwitch
,
except that it passes the wire we are switching away from to the new
wire.
- Inhibits: like the current wire.
- Switch: recurrent, now, restart state.
