Constructor & Destructor Documentation

◆ __construct()

RebuildRecentchanges::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Stability: stable: to call

Reimplemented from Maintenance.

Definition at line 43 of file rebuildrecentchanges.php.

References Maintenance\addDescription(), Maintenance\addOption(), and Maintenance\setBatchSize().

Member Function Documentation

◆ execute()

RebuildRecentchanges::execute ( )

Do the actual work.

All child classes will need to implement this

Returns: bool|null|void True for success, false for failure. Not returning a value, or returning null, is also interpreted as success. Returning false for failure will cause doMaintenance.php to exit the process with a non-zero exit status.
