The Collection interface

(No version information available, might only be in Git)

Introduction

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().

Interface synopsis

class Ds\Collection implements Countable, IteratorAggregate, JsonSerializable {
/* Methods */
abstract public clear(): void
abstract public copy(): Ds\Collection
abstract public isEmpty(): bool
abstract public toArray(): array
}

Changelog

Version Description
PECL ds 1.4.0 Collection implements IteratorAggregate now instead of just Traversable. (This change came to the polyfill in 1.4.1.)
