Setting Parser properties for use by this hook[edit]

Are you contributing to an extension and want to set a parser property that can later be used by the OutputPageParserOutput hook? The ParserOutput::setExtensionData() and ::appendExtensionData() methods and are available for your purpose.

For instance, if somewhere in your code, you define a property like:

$parser->getOutput()->setExtensionData( 'my_ext_foo', '...' );

In your method for this hook, you can fetch the value from the ParserOutput like this:

$parserOutput->getExtensionData( 'my_ext_foo' );
