Lambda

Lambda (Class)

The Lambda class is a collection of methods to support functional programming. It is ideally used with using Lambda and then acts as an extension to Iterable types.

On static platforms, working with the Iterable structure might be slower than performing the operations directly on known types, such as Array and List.

If the first argument to any of the methods is null, the result is unspecified.

See: https://haxe.org/manual/std-Lambda.html

Static Members

map(it: Iterable, f: Function): Array<map.B>

Creates a new Array by applying function f to all elements of it. The order of elements is preserved. If f is null, the result is unspecified.

Name Type
it Iterable
f Function
Returns
Array<map.B>

exists(it: Iterable, f: Function): Bool

Tells if it contains an element for which f is true.

This function returns true as soon as an element is found for which a call to f returns true.

If no such element is found, the result is false.

If f is null, the result is unspecified.

Name Type
it Iterable
f Function
Returns
Bool

fold(it: Iterable, f: Function, first: fold.B): fold.B

Functional fold on Iterable it, using function f with start argument first.

If it has no elements, the result is first.

Otherwise the first element of it is passed to f alongside first. The result of that call is then passed to f with the next element of it, and so on until it has no more elements.

If it or f are null, the result is unspecified.

Name Type
it Iterable
f Function
first fold.B
Returns
fold.B
