identity library
Classes
-
Identity<A>
-
Represents a container that wraps a single value.
-
MergedMap<K, V1, V2>
-
Properties
-
reduce
→ B Function(Identity<A>) Function<A, B>(B initial, B f(B, A))
-
An alias to fold function.
final
Functions
-
ap<A, B>(Identity<B Function(A)> f)
→ Identity<B> Function(Identity<A>)
-
Applies the function wrapped in an Identity to the value inside another Identity.
-
Extracts the value contained within the
identity.
-
flatMap<A, B>(Identity<B> f(A))
→ Identity<B> Function(Identity<A>)
-
Flat maps (or binds) the value inside an Identity using a given function.
-
fold<A, B>(B initial, B f(B, A))
→ B Function(Identity<A>)
-
Folds the value within an Identity monad.
-
foldMap<A, M>(BaseMonoid<M> monoid, M f(A))
→ M Function(Identity<A>)
-
Maps over the value within an Identity monad and then folds the result using a given
monoid.
-
letFn<A, B>(String name, B f(Map<String, A> fa), Map<String, A> fa)
→ MergedMap<String, A, B>
-
-
map<A, B>(B f(A))
→ Identity<B> Function(Identity<A>)
-
Transforms the value inside an Identity using a given function.
-
of<B>(B value)
→ Identity<B>
-
Wraps the provided value into an
Identity.
