Constructor & Destructor Documentation

__construct()

Wikibase\Lib\Formatters\DispatchingSnakFormatter::__construct	(		$format,
		PropertyDataTypeLookup	$dataTypeLookup,
		array	$formattersBySnakType,
		array	$formattersByDataType
	)

Parameters

string	$format	The output format generated by this formatter. All SnakFormatters provided via $formattersBySnakType and $formattersByDataType must be safe for this output format. This is checked by comparing the $format with what each SnakFormatter returns from getFormat(). MIME parameters are ignored for this check, so FORMAT_HTML is considered compatible with FORMAT_HTML_DIFF, etc.
PropertyDataTypeLookup	$dataTypeLookup
SnakFormatter[]	$formattersBySnakType	An associative array mapping snak types to SnakFormatter objects. If no formatter is defined for the a given snak type, $formattersByDataType will be checked for a SnakFormatter for the snak's data type.
SnakFormatter[]	$formattersByDataType	An associative array mapping data types to SnakFormatter objects. If no formatter is defined for the a given data type, the "*" key in this array is checked for a default formatter.

Exceptions

InvalidArgumentException

If any of the given formatters is incompatible with $format. Formats are assumed to be represented by MIME types, MIME parameters are ignored.
