class TraceInitializerFilter[Req, Rep] extends SimpleFilter[Req, Rep]

The TraceInitializerFilter takes care of span lifecycle events. It is always placed first in the service com.twitter.finagle.Filter chain (or last in the com.twitter.finagle.Stack) so that protocols with trace support will override the span resets, and still be properly reported here.

Note

This should be replaced by per-codec trace initializers that is capable of parsing trace information out of the codec.

Instance Constructors

  1. new TraceInitializerFilter(tracer: Tracer, newId: Boolean, fanout: Boolean = false)

    tracer

    An instance of a tracer to use. Eg: ZipkinTracer

    newId

    Set the next TraceId when the tracer is pushed (used for clients)

    fanout

    indicator of whether partitioning is enabled to wrap tracer in FanoutTracer

  4. def agnosticAndThen(next: TypeAgnostic): Filter[Req, Rep, Req, Rep]

    Convert the Filter.TypeAgnostic filter to a Filter and chain it with andThen.

  5. def andThen(factory: ServiceFactory[Req, Rep]): ServiceFactory[Req, Rep]

    Terminates a filter chain in a ServiceFactory.

    Terminates a filter chain in a ServiceFactory. For example,

    myFilter.andThen(myServiceFactory)
    factory

    a service factory that takes the output request type and the input response type.

  6. def andThen(service: Service[Req, Rep]): Service[Req, Rep]

    Terminates a filter chain in a Service.

    Terminates a filter chain in a Service. For example,

    myFilter.andThen(myService)
    service

    a service that takes the output request type and the input response type.

  7. def andThen[Req2, Rep2](next: Filter[Req, Rep, Req2, Rep2]): Filter[Req, Rep, Req2, Rep2]

    Chains a series of filters together:

    Chains a series of filters together:

    myModularService = handleExceptions.andThen(thrift2Pojo.andThen(parseString))
    next

    another filter to follow after this one

    Note

    synchronously thrown exceptions in the underlying service are automatically lifted into Future.exception.

  8. def andThenIf[Req2 >: Req, Rep2 <: Rep](condAndFilter: (Boolean, Filter[Req, Rep, Req2, Rep2])): Filter[Req, Rep, Req2, Rep2]

    Conditionally propagates requests down the filter chain.

    Conditionally propagates requests down the filter chain. This may be useful if you are statically wiring together filter chains based on a configuration file, for instance.

    condAndFilter

    a tuple of boolean and filter.

  9. def andThenIf[Req2 >: Req, Rep2 <: Rep](conditional: Boolean, filter: Filter[Req, Rep, Req2, Rep2]): Filter[Req, Rep, Req2, Rep2]

    Conditionally propagates requests down the filter chain.

    Conditionally propagates requests down the filter chain. This may be useful if you are statically wiring together filter chains based on a configuration file, for instance.

    conditional

    a boolean value indicating whether the filter should be included in the filter chain.

    filter

    the filter to be conditionally included.
