Constructor & Destructor Documentation

WikiExporter::__construct	(	$db,
		$history = `WikiExporter::CURRENT`,
		$buffer = `WikiExporter::BUFFER`,
		$text = `WikiExporter::TEXT`
	)

If using WikiExporter::STREAM to stream a large amount of data, provide a database connection which is not managed by LoadBalancer to read from: some history blob types will make additional queries to pull source data while the main query is still running.

Parameters

IDatabase	$db
int \| array	$history	One of WikiExporter::FULL, WikiExporter::CURRENT, WikiExporter::RANGE or WikiExporter::STABLE, or an associative array: offset: non-inclusive offset at which to start the query limit: maximum number of rows to return dir: "asc" or "desc" timestamp order
int	$buffer	One of WikiExporter::BUFFER or WikiExporter::STREAM
int	$text	One of WikiExporter::TEXT or WikiExporter::STUB

WikiExporter::outputPageStream ( $resultset )

protected

Runs through a query result set dumping page and revision records.

The result set should be sorted/grouped by page to avoid duplicate page records in the output.

Should be safe for streaming (non-buffered) queries, as long as it was made on a separate database connection not managed by LoadBalancer; some blob storage types will make queries to pull source data.
