PHP Manual

EventDnsBase::__construct

Constructs EventDnsBase object

Description

public EventDnsBase::__construct( EventBase $base , intbool $initialize )

Constructs EventDnsBase object.

Parameters

base

Event base.

initialize

If initialize is true, it attempts to use the underlying operating system defaults to configure the DNS base senibly. If it is false, the DNS base is left unconfigured, with no nameservers or options set. In the latter case the DNS base should be configured manually, e.g. with EventDnsBase::parseResolvConf.

If initialize is an integer, it must be one of the following flags:

Flag Description
EventDnsBase::DISABLE_WHEN_INACTIVE Do not prevent the libevent event loop from exiting when we have no active DNS requests.
EventDnsBase::INITIALIZE_NAMESERVERS Process the resolv.conf.
EventDnsBase::NAMESERVERS_NO_DEFAULT Do not add default nameserver if there are no nameservers in the resolv.conf.

Errors/Exceptions

If initialize has a type other than intbool, a TypeError is thrown.

If the value of initialize is invalid, a EventException is thrown.
