Member Function Documentation

checkPermissions()

ApiImageRotate::checkPermissions (   $user,   $title  )

protected

Checks that the user has permissions to perform rotations.

Parameters

User	$user	The user to check
Title	$title

Returns

string|null Permission error message, or null if there is no error

Definition at line 139 of file ApiImageRotate.php.

References $title, $user, and ApiBase\parseMsg().

Referenced by execute().

execute()

ApiImageRotate::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.

getAllowedParams()

ApiImageRotate::getAllowedParams

(

$flags = 0

)

Definition at line 163 of file ApiImageRotate.php.

References $flags, getPageSet(), ApiBase\PARAM_HELP_MSG, ApiBase\PARAM_REQUIRED, ApiBase\PARAM_TYPE, and true.

getExamplesMessages()

ApiImageRotate::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

Returns

array

Reimplemented from ApiBase.

Definition at line 184 of file ApiImageRotate.php.

getPageSet()

ApiImageRotate::getPageSet ( )

private

Get a cached instance of an ApiPageSet object.

Returns

ApiPageSet

Definition at line 125 of file ApiImageRotate.php.

References $mPageSet, and NS_FILE.

Referenced by execute(), and getAllowedParams().

isWriteMode()

ApiImageRotate::isWriteMode

(

)

Indicates whether this module requires write mode.

Returns

bool

Reimplemented from ApiBase.

Definition at line 159 of file ApiImageRotate.php.

mustBePosted()

ApiImageRotate::mustBePosted

(

)

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

Returns

bool

Reimplemented from ApiBase.

Definition at line 155 of file ApiImageRotate.php.

needsToken()

ApiImageRotate::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.

Returns

string|false

Reimplemented from ApiBase.
