The Collection interface

(PECL ds >= 1.0.0)

Introduzione

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().

Sommario dell'interfaccia

interface Ds\Collection extends Countable, IteratorAggregate, JsonSerializable {

/* Metodi */

public function clear(): void

public function copy(): Ds\Collection

public function isEmpty(): bool

public function toArray(): array

/* Metodi ereditati */

public function Countable::count(): int

public function IteratorAggregate::getIterator(): Traversable

public function JsonSerializable::jsonSerialize(): mixed

}

Log delle modifiche
