The Collection interface

はじめに

Collection is the base interface which covers functionality common to all the data structures in this library. It guarantees that all structures are traversable, countable, and can be converted to json using json_encode.

インターフェイス概要

Ds\Collection extends Countable IteratorAggregate JsonSerializable
/* メソッド */
public void Ds\Collection::clear()
public Ds\Collection Ds\Collection::copy()
public bool Ds\Collection::isEmpty()
public array Ds\Collection::toArray()
/* 継承したメソッド */
public int Countable::count()
public Traversable IteratorAggregate::getIterator()
public mixed JsonSerializable::jsonSerialize()

バージョン 説明
PECL ds 1.4.0 Collection implements IteratorAggregate now instead of just Traversable. (This change came to the polyfill in 1.4.1.)
