PHP マニュアル: Constructs EventDnsBase object

説明

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

Constructs EventDnsBase object.

パラメータ

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	説明
`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`.

エラー / 例外

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

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

変更履歴

バージョン	説明
PECL event 3.1.3	If `initialize` has a type other than intbool, a TypeError is thrown.
PECL event 3.1.0RC1	The type of the `initialize` parameter has been changed from bool to mixed. The value can be either bool (preserving the previous meaning) or one of the following constants: `EventDnsBase::DISABLE_WHEN_INACTIVE`, `EventDnsBase::INITIALIZE_NAMESERVERS`, or `EventDnsBase::NAMESERVERS_NO_DEFAULT`.
