Member Function Documentation

◆ execute()

ApiPurge::execute ( )

Purges the cache of a page.

Reimplemented from ApiBase.

Definition at line 60 of file ApiPurge.php.

References $params, ApiBase\addWarning(), ApiBase\dieBlocked(), ApiBase\extractRequestParams(), MediaWiki\Context\ContextSource\getAuthority(), ApiBase\getModuleName(), ApiBase\getResult(), ApiBase\setContinuationManager(), and wfTimestampNow().

◆ getAllowedParams()

ApiPurge::getAllowedParams ( $flags = 0 )

Definition at line 181 of file ApiPurge.php.

References ApiBase\PARAM_HELP_MSG.

◆ getExamplesMessages()

ApiPurge::getExamplesMessages ( )

protected

Returns usage examples for this module.

Return value has query strings as keys, with values being either strings (message key), arrays (message key + parameter), or Message objects.

Do not call this base class implementation when overriding this method.

Since: 1.25

Stability: stable: to override

Returns: array

Reimplemented from ApiBase.

Definition at line 196 of file ApiPurge.php.

◆ getHelpUrls()

ApiPurge::getHelpUrls ( )

Return links to more detailed help pages about the module.

Since: 1.25, returning boolean false is deprecated

Stability: stable: to override

Returns: string|array

Reimplemented from ApiBase.

Definition at line 208 of file ApiPurge.php.

◆ isWriteMode()

ApiPurge::isWriteMode ( )

Indicates whether this module requires write mode.

This should return true for modules that may require synchronous database writes. Modules that do not need such writes should also not rely on primary database access, since only read queries are needed and each primary DB is a single point of failure. Additionally, requests that only need replica DBs can be efficiently routed to any datacenter via the Promise-Non-Write-API-Action header.

Stability: stable: to override

Returns: bool

Reimplemented from ApiBase.

Definition at line 173 of file ApiPurge.php.

◆ mustBePosted()

ApiPurge::mustBePosted ( )

Indicates whether this module must be called with a POST request.

Stability: stable: to override

Returns: bool

Reimplemented from ApiBase.

Definition at line 177 of file ApiPurge.php.
