Example 7 with ConfigurationRuntimeException

the class ConfigSubscriber method subscribe.

/**
 * Use this convenience method if you only want to subscribe on <em>one</em> config, and want generic error handling.
 * Implement {@link SingleSubscriber} and pass to this method.
 * You will get initial config, and a config thread will be started. The method will throw in your thread if initial
 * configuration fails, and the config thread will print a generic error message (but continue) if it fails thereafter. The config
 * thread will stop if you {@link #close()} this {@link ConfigSubscriber}.
 *
 * @param <T> ConfigInstance type
 * @param singleSubscriber The object to receive config
 * @param configClass      The class, typically generated from a def-file using config-class-plugin
 * @param configId         Identifies the service in vespa-services.xml
 * @return The handle of the config
 * @see #startConfigThread(Runnable)
