com.wavefront.agent.handlers.ReportableEntityHandlerFactoryImpl

All Implemented Interfaces:

ReportableEntityHandlerFactory

public class ReportableEntityHandlerFactoryImpl
extends Object
implements ReportableEntityHandlerFactory

Caching factory for ReportableEntityHandler objects. Makes sure there's only one handler for each HandlerKey, which makes it possible to spin up handlers on demand at runtime, as well as redirecting traffic to a different pipeline.
