Indexclass Lambda
Available in flash8, neko, js, flash, php, cpp, cs, java
The Lambda
class is a collection of functional methods in order to
use functional-style programming with haXe.
- static function array<A>(it : Iterable<A>) : Array<A>
- Creates an
Array
from an Iterable
- static function concat<T>(a : Iterable<T>, b : Iterable<T>) : List<T>
- Returns a list containing all items of 'a' followed by all items of 'b'
- static function count<A>(it : Iterable<A>, ?pred : A -> Bool) : Int
- Count the number of elements in an
Iterable
having pred
returning true. - static function empty(it : Iterable<Dynamic>) : Bool
- Tells if an iterable does not contain any element.
- static function exists<A>(it : Iterable<A>, f : A -> Bool) : Bool
- Tells if at least one element of the iterable is found by using the specific function.
- static function filter<A>(it : Iterable<A>, f : A -> Bool) : List<A>
- Return the list of elements matching the function 'f'
- static function fold<A, B>(it : Iterable<A>, f : A -> B -> B, first : B) : B
- Functional 'fold' using an
Iterable
- static function foreach<A>(it : Iterable<A>, f : A -> Bool) : Bool
- Tells if all elements of the iterable have the specified property defined by
f
. - static function has<A>(it : Iterable<A>, elt : A, ?cmp : A -> A -> Bool) : Bool
- Tells if the element is part of an iterable. The comparison
is made using the
==
operator. Optionally you can pass as
a third parameter a function that performs the comparison.
That function must take as arguments the two items to
compare and returns a boolean value. - static function indexOf<T>(it : Iterable<T>, v : T) : Int
- Returns the index of the item in the given Iterable, depending on the order of the Iterator.
Returns -1 if the item was not found.
- static function iter<A>(it : Iterable<A>, f : A -> Void) : Void
- Call the function 'f' on all elements of the
Iterable
'it'. - static function list<A>(it : Iterable<A>) : List<A>
- Creates a
List
from an Iterable
- static function map<A, B>(it : Iterable<A>, f : A -> B) : List<B>
- Creates a new
Iterable
by appling the function 'f' to all
elements of the iterator 'it'. - static function mapi<A, B>(it : Iterable<A>, f : Int -> A -> B) : List<B>
- Similar to
map
, but also pass an index for each item iterated.
