Detailed Description

Represents a title within MediaWiki.

Optionally may contain an interwiki designation or namespace.

Note: This class can fetch various kinds of data from the database; however, it does so inefficiently.; Consider using a TitleValue object instead. TitleValue is more lightweight and does not rely on global state or the database.
