Member Function Documentation

execute()

ApiFileRevert::execute

(

)

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

Reimplemented from ApiBase.

References ApiBase\checkTitleUserPermissions(), ApiBase\extractRequestParams(), MediaWiki\Context\ContextSource\getAuthority(), ApiBase\getErrorFormatter(), ApiBase\getModuleName(), ApiBase\getResult(), ApiBase\useTransactionalTimeLimit(), and validateParameters().

getAllowedParams()

ApiFileRevert::getAllowedParams

(

)

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Stability: stable

to override

Returns

array

Reimplemented from ApiBase.

Definition at line 126 of file ApiFileRevert.php.

getExamplesMessages()

ApiFileRevert::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 146 of file ApiFileRevert.php.

getHelpUrls()

ApiFileRevert::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 154 of file ApiFileRevert.php.

isWriteMode()

ApiFileRevert::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 122 of file ApiFileRevert.php.

mustBePosted()

ApiFileRevert::mustBePosted

(

)

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

Stability: stable

to override

Returns

bool

Reimplemented from ApiBase.

Definition at line 118 of file ApiFileRevert.php.

needsToken()

ApiFileRevert::needsToken

(

)

Returns the token type this module requires in order to execute.

Modules are strongly encouraged to use the core 'csrf' type unless they have specialized security needs. If the token type is not one of the core types, you must use the ApiQueryTokensRegisterTypes hook to register it.

Returning a non-falsey value here will force the addition of an appropriate 'token' parameter in self::getFinalParams(). Also, self::mustBePosted() must return true when tokens are used.

In previous versions of MediaWiki, true was a valid return value. Returning true will generate errors indicating that the API module needs updating.

Stability: stable

to override

Returns

string|false

Reimplemented from ApiBase.

Definition at line 142 of file ApiFileRevert.php.

validateParameters()

ApiFileRevert::validateParameters ( )

protected

Validate the user parameters and set $this->archiveName and $this->file.

Throws an error if validation fails
