the class RequestHandler method assignRequestDefault.

/**
 * Method used to assign a given request to a resolver. Does take a given blacklist of resolvers into account.
 * Uses the default assigning strategy: {@link AssigningStrategy#PRIORITY_BASED}
 *
 * @param manager                The manager to modify.
 * @param request                The request to assign.
 * @param resolverTokenBlackList Each resolver that has its token in this blacklist will be skipped when checking for a possible resolver.
 * @return The token of the resolver that has gotten the request assigned, null if none was found.
 *
 * @throws IllegalArgumentException is thrown when the request is unknown to this manager.
