Static Public Member Functions

Static Public Member Functions inherited from Maintenance
static	getTermSize ()
	Get the terminal size as a two-element array where the first element is the width (number of columns) and the second element is the height (number of rows).
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, Config $config)
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)

Constructor & Destructor Documentation

__construct()

DumpIterator::__construct

(

)

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from Maintenance.

Reimplemented in CompareParsers, SearchDump, and PreprocessDump.

Definition at line 41 of file dumpIterator.php.

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

Member Function Documentation

conclusions()

DumpIterator::conclusions

disableInterwikis()

static DumpIterator::disableInterwikis ( $prefix, & $data )

static

Definition at line 113 of file dumpIterator.php.

execute()

DumpIterator::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.
