◆ getId()

MediaWiki\Storage\NameTableStore::getId ( $name )

Get the id of the given name.

If the name doesn't exist this will throw. This should be used in cases where we believe the name already exists or want to check for existence.

◆ getMap()

MediaWiki\Storage\NameTableStore::getMap ( )

Get the whole table, in no particular order as a map of ids to names.

This method could be subject to DB or cache lag.

Returns: string[] keys are the name ids, values are the names themselves Example: [ 1 => 'foo', 3 => 'bar' ]
