data T key a

Constructors

Cons

Fields

• initial :: Map key a
• stream :: T StrictTime [(key, a)]

Instances

(Show a, Show key) => Show (T key a)

Methods

showsPrec :: Int -> T key a -> ShowS

show :: T key a -> String

showList :: [T key a] -> ShowS

Semigroup (T key y)

Methods

(<>) :: T key y -> T key y -> T key y

sconcat :: NonEmpty (T key y) -> T key y

stimes :: Integral b => b -> T key y -> T key y

Monoid (T key y)

Methods

mempty :: T key y

mappend :: T key y -> T key y -> T key y

mconcat :: [T key y] -> T key y

Read (T key a)

Methods

null :: T key a -> Bool

length :: T key a -> Int

(NFData key, NFData a) => NormalForm (T key a)

Methods

evaluateHead :: T key a -> ()

Ord key => Transform (T key y)

For reverse you must make sure, that all controller events have an corresponding initial value. Controllers that miss an initial value their last constant piece will be undefined.

Methods

take :: Int -> T key y -> T key y

drop :: Int -> T key y -> T key y

dropMarginRem :: Int -> Int -> T key y -> (Int, T key y)

splitAt :: Int -> T key y -> (T key y, T key y)

reverse :: T key y -> T key y

mapStream :: (T StrictTime [(key, a)] -> T StrictTime [(key, a)]) -> T key a -> T key a
