Various additional operations on lists
Synopsis
- mapI :: (a -> Bool) -> (a -> [a]) -> [a] -> [a]
- mapI2 :: (a -> Bool) -> (a -> b) -> (a -> [b]) -> [a] -> [b]
- mapI22 :: (a -> Bool) -> (a -> b) -> (b -> d) -> (a -> c) -> (c -> d) -> [a] -> [d]
- mapI12 :: (a -> Bool) -> (a -> c) -> (a -> b) -> (b -> c) -> [a] -> [c]
- mapI21 :: (a -> Bool) -> (a -> b) -> (b -> c) -> (a -> c) -> [a] -> [c]
Operations to apply a function or different functions (some can create an inner list) to an element of the outer list
mapI :: (a -> Bool) -> (a -> [a]) -> [a] -> [a] Source #
Function that applies additional function f :: a -> [a]
to a
if p a = True
mapI2 :: (a -> Bool) -> (a -> b) -> (a -> [b]) -> [a] -> [b] Source #
Function that applies additional function f :: a -> b
to a
if p a = True
and otherwise another function g :: a -> [b]
to [a]
to obtain [b]
mapI22 :: (a -> Bool) -> (a -> b) -> (b -> d) -> (a -> c) -> (c -> d) -> [a] -> [d] Source #
Function that can apply two different ways of computing something depending of the predicate value p :: a -> Bool
and the structure of transition the data for the [a]
.
It is used if there are two ways to transform data both of them consists of two applied functoins. Similar to arrow techniques.
mapI12 :: (a -> Bool) -> (a -> c) -> (a -> b) -> (b -> c) -> [a] -> [c] Source #
Function that can apply two different ways of computing something depending of the predicate value p :: a -> Bool
and the structure of transition the data for the [a]
.
It is used if there are two ways to transform data and the first one consists of one function and another -- from two applied consequently ones. Similar to arrow techniques.
mapI21 :: (a -> Bool) -> (a -> b) -> (b -> c) -> (a -> c) -> [a] -> [c] Source #
Function that can apply two different ways of computing something depending of the predicate value p :: a -> Bool
and the structure of transition the data for the [a]
.
It is used if there are two ways to transform data and the first one consists of two applied consequently functions and the second -- from one applied function. Similar to arrow techniques.
