Detailed Description

This class contains a list of pages that the client has requested.

Initially, when the client passes in titles=, pageids=, or revisions= parameter, an instance of the ApiPageSet class will normalize titles, determine if the pages/revisions exist, and prefetch any additional page data requested.

When a generator is used, the result of the generator will become the input for the second instance of this class, and all subsequent actions will use the second instance for all their work.

Since: 1.21 derives from ApiBase instead of ApiQueryBase

◆ __construct()

ApiPageSet::__construct	(	ApiBase	$dbSource,

◆ populateFromQueryResult()

ApiPageSet::populateFromQueryResult	(		$db,

Parameters

array $revIDs Array of revision IDs

Definition at line 749 of file ApiPageSet.php.

References initFromRevIDs().

◆ populateFromTitles()

ApiPageSet::populateFromTitles ( $titles )

Populate this PageSet from a list of Titles.

Parameters

array $titles Array of Title objects

Definition at line 720 of file ApiPageSet.php.

References initFromTitles().

◆ populateGeneratorData()

ApiPageSet::populateGeneratorData	(	&	$result,
		array	$path = [] )

Populate the generator data for all titles in the result.

The page data may be inserted into an ApiResult object or into an associative array. The $path parameter specifies the path within the ApiResult or array to find the "pages" node.

The "pages" node itself must be an associative array mapping the page ID or fake page ID values returned by this pageset (see self::getAllTitlesByNamespace() and self::getSpecialTitles()) to associative arrays of page data. Each of those subarrays will have the data from self::setGeneratorData() merged in.

Data that was set by self::setGeneratorData() for pages not in the "pages" node will be ignored.

Parameters

ApiResult \| array	&$result
array	$path

Returns: bool Whether the data fit

References $path, $title, ApiResult\addValue(), and NS_SPECIAL.

◆ processDbRow()

◆ processTitlesArray()

ApiPageSet::processTitlesArray ( $titles )

private

Given an array of title strings, convert them into Title objects.

Alternatively, an array of Title objects may be given. This method validates access rights for the title, and appends normalization values to the output.

Parameters

array $titles Array of Title objects or strings

Returns: LinkBatch

◆ requestField()

ApiPageSet::requestField ( $fieldName )

Must be called before execute()

Parameters

string $fieldName Field name

Definition at line 288 of file ApiPageSet.php.

◆ resolvePendingRedirects()

ApiPageSet::resolvePendingRedirects ( )

private

Resolve any redirects in the result if redirect resolution was requested.

This function is called repeatedly until all redirects have been resolved.

Referenced by executeInternal(), initFromPageIds(), and initFromTitles().

◆ setGeneratorData()

ApiPageSet::setGeneratorData	(	Title	$title,
		array	$data )

Set data for a title.

This data may be extracted into an ApiResult using self::populateGeneratorData. This should generally be limited to data that is likely to be particularly useful to end users rather than just being a dump of everything returned in non-generator mode.

Redirects here will not be followed, even if 'redirects' was specified, since in the case of multiple redirects we can't know which source's data to use on the target.

Parameters

Title	$title
array	$data

Definition at line 1285 of file ApiPageSet.php.

References $title.

◆ setRedirectMergePolicy()

ApiPageSet::setRedirectMergePolicy ( $callable )

Controls how generator data about a redirect source is merged into the generator data for the redirect target.

When not set no data is merged. Note that if multiple titles redirect to the same target the order of operations is undefined.

Example to include generated data from redirect in target, prefering the data generated for the destination when there is a collision:

$pageSet->setRedirectMergePolicy( function( array $current, array $new ) {
    return $current + $new;
} );

Parameters

callable | null $callable Recieves two array arguments, first the generator data for the redirect target and second the generator data for the redirect source. Returns the resulting generator data to use for the redirect target.
