Detailed Description
Constructor & Destructor Documentation
◆ __construct()
| ViewCLI::__construct | ( | ) |
Default constructor.
Children should call this first if implementing their own constructors
- Stability: stable
- to call

Member Function Documentation
◆ execute()
| ViewCLI::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.
