Returns the processed value of a named route parameter.

Raw URL parameters are processed by the parameter conversion system, which does operations such as converting entity ID parameters to fully-loaded entities. For example, the path node/12345 would have a raw node ID parameter value of 12345, while the processed parameter value would be the corresponding loaded node object.

Parameters

string $parameter_name: The parameter name.

Return value

mixed|null The parameter value. NULL if the route doesn't define the parameter or if the parameter value can't be determined from the request.
