ClosureIteratorIterator

Class ClosureIteratorIterator.

An extended IteratorIterator that applies a closure transformation to each element during iteration.

This class allows applying a transformation function dynamically while iterating over an existing Traversable.

Usage Example:

---

• Full name: \FastForward\Iterator\ClosureIteratorIterator
• Parent class: \FastForward\Iterator\CountableIteratorIterator

Methods

__construct

Initializes the ClosureIteratorIterator.

public __construct(iterable $iterator, \Closure $closure): mixed

Parameters:

Parameter	Type	Description
$iterator	iterable	the underlying iterator to wrap
$closure	\Closure	the transformation function applied to each element

---

current

Returns the current transformed element.

public current(): mixed

The closure is applied to the original current element of the iterator.

Return Value:

the transformed element

---

Inherited methods

count

Counts the number of elements in the iterable.

public count(): int

If the inner iterator implements Countable, it uses that. Otherwise, it counts the elements by iterating through them.

Return Value:

the number of elements in the iterable
