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

A com.twitter.finagle.Filter that restricts request concurrency according to the given com.twitter.concurrent.AsyncSemaphore. Requests that are unable to acquire a permit are failed immediately with a com.twitter.finagle.Failure that signals a restartable or idempotent process.

  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.

    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.
