TrimIteratorIterator

Class TrimIteratorIterator.

An iterator that trims each value within a Traversable.

This class extends ClosureIteratorIterator and applies trim() to each element, removing leading and trailing characters based on the specified character mask.

Usage Example:

---

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

Methods

__construct

Initializes the TrimIteratorIterator.

public __construct(iterable $iterator, string|null $characters = \self::DEFAULT_CHARACTERS): mixed

Parameters:

Parameter	Type	Description
$iterator	iterable	the iterator containing values to be trimmed
$characters	string|null	A string defining the characters to be trimmed.

---

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

---

__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
