Index of values

The negation of =*.

Compare two objects structurally with (=), falling back to physical equality with (==) if this is not possible.

accum_b is identical to accum_e but produces a behavior rather than an event.

accum_e i e creates a event with memory which occurs whenever its internal state changes.

behavior_source force start stop creates a behavior.

changes b occurs whenever b changes, and has the new value of b.

changesq b is similar to changes b but detects changes using physical equality.

collapse_b b is a behavior isomorphic to the current value of b.

collapse_e b is an event isomorphic to the current value of b.

collect_b is identical to collect_e but produces a behavior rather than an event.

collect_e f i e is similar to accum_e but passes the value of the event e to the function f in order to update the internal state.

delta f b is similar to changesq b but the value of the event it creates is determined by applying f to the old and new values, respectively, of b.

edge_e b occurs whenever b transitions from None to Some v, and has the value v.

Create a new event receiver.

event_source start stop creates an event.

filter_e f e passes all occurrences of e for which f returns true.

fix_b is identical to fix_e but works with a behavior.

fix_e g f allows f to reference an event before it is defined: the result of applying f to this "phantom" event is passed to g, whose output is used to "fill in" the phantom event.

gate b e is a behavior which follows b, but changes only when the event e occurs.

hold i e is a behavior equal to the last occurrence of e (or i, if e has not yet occurred).

latch b e is similar to snapshot b e but carries the value b had just before e occured.

lift0 a is a behavior which is always equal to a.

lift1 f returns a function which, when applied to a behavior, returns a behavior which is always equal to f applied to the current value of the behavior.

map_e f e transforms the value of the event a with f.

map_wait_e f e is a convenience function similar to map in that it creates an event by applying the function f to the event e whenever e occurs.

may_e e occurs whenever e is Some v, and has the value v.

merge_e l occurs when any event in l occurs, with the value of that event.

never is an event which never occurs.

Create a new cell with the given initial value.

now is an event which occurs exactly once, when a it is first instantiated (i.e.

once_e e passes only the first occurrence of e.

par_b l is a behavior whose value is a list of the values of all behaviors in the list l.

par_e l occurs when at least one event in l occurs, with the value of all occuring events joined in a list.

unregister h destroys the endpoint h.

register_e e marks the event e as an endpoint.

scollapse_b g i e is similar to collapse_b but allows state to be maintained across switches.

Send a value to an event receiver.

Set the value of a cell.

snapshot b e is an event which occurs with the value of b when the event e occurs.

snapshot_e e trigger occurs whenever event trigger occurs.

sswitch_b g f i e is similar to switch_b but allows state to be maintained across switches.

switch_b i e is a behavior isomorphic to the last occurrence of e (or i, if e has not yet occurred).

switch_e i e is an event isomorphic to the last occurrence of e (or i, if e has not yet occurred).

tag_e v a replaces the value of the event a with v.

track i b is a behavior which follows b whenever it is not None.

unzip_b b produces two behaviors whose values are the first and second halves of the value of b.

unzip_e e produces two events synchronous with e whose values are the first and second halves of the value of e.

when_e b occurs whenever b becomes true.

zip_b a b is a behavior with the value of a paired with b.

zip_e a b occurs whenever both a and b occur, and has the value of a paired with b.
