Constructor & Destructor Documentation

◆ __construct()

Wikibase\Lib\Formatters\DispatchingSnakFormatter::__construct (   $format,
PropertyDataTypeLookup  $dataTypeLookup,
array  $formattersBySnakType,
array  $formattersByDataType 
)
Parameters
string$formatThe 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[]$formattersBySnakTypeAn associative array mapping snak types to SnakFormatter objects. If no formatter is defined for the a given snak type, $formattersByDataType will be checked for a SnakFormatter for the snak's data type.
SnakFormatter[]$formattersByDataTypeAn 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
InvalidArgumentExceptionIf any of the given formatters is incompatible with $format. Formats are assumed to be represented by MIME types, MIME parameters are ignored.
