Detailed Description

Represents result of \Wikibase\Lib\Store\EntityRevisionLookup::getLatestRevisionId method call.

Is immutable.

The idea behind the design is to force developer to handle all the possible cases.

How to create:

$concreteRevision = LatestRevisionIdResult::concreteRevision( 123 );
$revisionRedirectsToQ7 = LatestRevisionIdResult::redirect( 123, new ItemId( 'Q7' ) );

Example of usage:

$result = $someResult->onRedirect( function ( int $revisionId, EntityId $redirectsTo ) {
return 'redirect';
} )
->onNonexistentEntity( function () {
return 'nonexistent';
} )
->onConcreteRevision( function ( int $revisionId ) {
return 'concrete';
} )
->map();
// $result will be one of 'redirect', 'nonexistent' or 'concrete' depending
// on the $someResult type
