loadServiceDenied

object loadServiceDenied extends GlobalFlag[Set[String]]

A deny list of implementations to ignore. Keys are the fully qualified class names. Any other implementations that are found via LoadService.apply are eligible to be used.

As an example, here's how to filter out OstrichStatsReceiver, OstrichExporter and CommonsStatsReceiver using a global flag:

-Dcom.twitter.finagle.util.loadServiceDenied=com.twitter.finagle.stats.OstrichStatsReceiver,com.twitter.finagle.stats.OstrichExporter,com.twitter.finagle.stats.CommonsStatsReceiver

We need to pass the arguments as Java property values instead of as Java application arguments (regular TwitterServer flags) because app.LoadService may be loaded before application arguments are parsed.

Note: this lives in com.twitter.finagle.util for historical reasons as this flag began its life in Finagle and in order to keep backwards compatibility it remains in that package.

GlobalFlag
Note
Called via reflection assuming it will be a static method on a singleton object. This causes problems for Java developers who want to create a GlobalFlag as there is no good means for them to have it be a static method. Thus, Java devs must add a method public static Flag<?> globalFlagInstance() which returns the singleton instance of the flag. See JavaGlobalFlag for more details.
