Example 2 with Payload

use of com.yahoo.vespa.config.protocol.Payload in project vespa by vespa-engine.

the class JRTConfigSubscription method toConfigInstance.

/**
 * This method should ideally throw new MissingConfig/Configuration exceptions and let the caller
 * catch them. However, this would make the code in JRT/File/RawSource uglier.
 * Alternatively, it could return a SetConfigStatus object with an int and an error message.
 *
 * @param jrtRequest a config request
 * @return an instance of a config class (subclass of ConfigInstance)
