Detailed Description

Generic operation result class Has warning/error list, boolean status and arbitrary value.

"Good" means the operation was completed with no warnings or errors.

"OK" means the operation was partially or wholly completed.

An operation which is not OK should have errors so that the user can be informed as to what went wrong. Calling the fatal() function sets an error message and simultaneously switches off the OK flag.

The recommended pattern for functions returning StatusValue objects is to return a StatusValue unconditionally, both on success and on failure (similarly to Option, Maybe, Promise etc. objects in other languages) – so that the developer of the calling code is reminded that the function can fail, and so that a lack of error-handling will be explicit.

This class accepts any MessageSpecifier objects. The use of Message objects should be avoided when serializability is needed. Use MessageValue in that case instead.

Stability: newable

Stability: stable: to extend

Since: 1.25 @template T Type of the value stored in the status when the operation result is OK. May be 'never' to indicate that there's no meaningful value, and that this status is only used to keep track of errors and warnings.

Constructor & Destructor Documentation

◆ __construct()

StatusValue::__construct ( )

Reimplemented in MediaWiki\Status\Status.

Definition at line 75 of file StatusValue.php.

Member Function Documentation

◆ __toString()

StatusValue::__toString ( )

Returns a string representation of the status for debugging.

This is fairly verbose and may change without notice.

Returns: string

Definition at line 493 of file StatusValue.php.

◆ cast()

static StatusValue::cast ( StatusValue $sv )

static

Succinct helper method to wrap a StatusValue in some other specific subclass.

One place where this is useful is when formatting StatusValue objects:

$this->getOutput()->addHtml( Status::cast( $sv )->getHTML() );

Also, several code paths in MediaWiki core use Status::wrap() to turn a returned StatusValue into a Status (e.g. ()); in such cases, cast() can be used to "restore" the original type. $form = HTMLForm::factory( 'ooui', [ ... ], $this->getContext() ) ->setSubmitCallback( function ( array $data, HTMLForm $form ) { return CustomStatusValue::newGood( $data ); ); $result = $form->tryAuthorizedSubmit(); // $result is a generic Status if ( $result && $result->isGood() ) { $result = CustomStatusValue::cast( $result ); // $result is a CustomStatusValue again } To support this pattern, StatusValue subclasses should not add any new properties: all data should be stored in the standard fields, chiefly self::$value and self::$statusData. (Making them associative arrays can help to keep the data extensible.)

Parameters

StatusValue $sv

Returns: static

Definition at line 133 of file StatusValue.php.

StatusValue::error	(		$message,
			$parameters )

◆ getErrorsByType()

StatusValue::getErrorsByType ( $type )

Each entry is a map of:

message: string message key or MessageSpecifier

◆ getMessages()

StatusValue::getMessages ( ?string $type = null )
