The EventConfig class

(PECL event >= 1.2.6-beta)

Introduction

Represents configuration structure which could be used in construction of the EventBase.

final class EventConfig {

/* Constants */

const int FEATURE_ET = 1;

const int FEATURE_O1 = 2;

const int FEATURE_FDS = 4;

/* Methods */

public avoidMethod( string $method ): bool

public requireFeatures( int $feature ): bool

public setFlags( int $flags ): bool

public setMaxDispatchInterval( int $max_interval , int $max_callbacks , int $min_priority ): void

}

EventConfig::FEATURE_ET: Requires a backend method that supports edge-triggered I/O.
EventConfig::FEATURE_O1: Requires a backend method where adding or deleting a single event, or having a single event become active, is an O(1) operation.
EventConfig::FEATURE_FDS: Requires a backend method that can support arbitrary file descriptor types, and not just sockets.

EventConfig::avoidMethod — Tells libevent to avoid specific event method
EventConfig::__construct — Constructs EventConfig object
EventConfig::requireFeatures — Enters a required event method feature that the application demands
EventConfig::setFlags — Sets one or more flags to configure the eventual EventBase will be initialized
EventConfig::setMaxDispatchInterval — Prevents priority inversion
