Method Detail

__construct() public ¶

__construct( array|Traversable $items , callable $callback )

Creates an iterator from another iterator that will modify each of the values by converting them using a callback function.

Each time the callback is executed it will receive the value of the element in the current iteration, the key of the element and the passed $items iterator as arguments, in that order.

Parameters

array|Traversable $items: The items to be filtered.
callable $callback: Callback.

Throws

InvalidArgumentException
If passed incorrect type for items.

Overrides

Cake\Collection\Collection::__construct()

current() public ¶

current( )

Returns the value returned by the callback after passing the current value in the iteration

Returns

mixed

Overrides

IteratorIterator::current()

unwrap() public ¶

unwrap( )

We perform here some strictness analysis so that the iterator logic is bypassed entirely.

Returns

Iterator

__debugInfo() public ¶

__debugInfo( )

Returns an array that can be used to describe the internal state of this object.

Returns

array

count() public ¶

count( )

Returns the amount of elements in the collection.

Returns

integer

Implementation of

Cake\Collection\CollectionInterface::count()

countKeys() public ¶

countKeys( )

Returns the number of unique keys in this iterator. This is, the number of elements the collection will contain after calling toArray()

Returns

integer

Implementation of

Cake\Collection\CollectionInterface::countKeys()

serialize() public ¶

serialize( )

Returns a string representation of this object that can be used to reconstruct it

Returns

string

Implementation of

Serializable::serialize()

unserialize() public ¶

unserialize( string $collection )

Unserializes the passed string and rebuilds the Collection instance

Parameters

string $collection: The serialized collection

Implementation of

Serializable::unserialize()
