Constructor & Destructor Documentation

◆ __construct()

CategoryChangesAsRdf::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Stability: stable
to call

Reimplemented from Maintenance.

Member Function Documentation

◆ execute()

CategoryChangesAsRdf::execute ( )

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.
