The Collection interface

(PECL ds >= 1.0.0)

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

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

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.)
