tunable

Type Members

1. final class JsonTunableMapper extends AnyRef

   

   Parses a given JSON string into a TunableMap.

   Parses a given JSON string into a TunableMap. The expected format is:

   { "tunables": [ { "id" : "$id1", "value" : $value, "type" : "$class" }, { "id" : "$id2", "value" : $value, "type" : "$class" } ] }

   Where $id1 and $id2 are unique identifiers used to access the Tunable, $value is the value, and $class is the fully-qualified class name (e.g. com.twitter.util.Duration)

   If the JSON is invalid, or contains duplicate ids for Tunables, parse will return a Throw. Otherwise, parse returns Return[TunableMap

2. trait ServiceLoadedTunableMap extends TunableMap

   

   TunableMap loaded through com.twitter.app.LoadService.

4. abstract class TunableMap extends AnyRef
