Additional Inherited Members

- Static Public Member Functions inherited from Maintenance
static posix_isatty ( $fd)
 Wrapper for posix_isatty() We default as considering stdin a tty (for nice readline methods) but treating stout as not a tty to avoid color codes.
 
static readconsole ( $prompt='> ')
 Prompt the console for input.
 
static requireTestsAutoloader ()
 Call this to set up the autoloader to allow classes to be used from the tests directory.
 
static setLBFactoryTriggers (LBFactory $LBFactory)
 
static shouldExecute ()
 Should we execute the maintenance script, or just allow it to be included as a standalone class? It checks that the call stack only includes this function and "requires" (meaning was called from the file scope)
 
- Public Attributes inherited from Maintenance
resource $fileHandle
 Used when creating separate schema files.
 
array $orderedOptions = []
 Used to read the options in the order they were passed.
