Type Members

1. class ClientDeserializeCtx[Rep] extends (Array[Byte]) ⇒ ReqRep

   

   Used by Thrift and ThriftMux Client to facilitate giving the Finagle stack access to various data that are computed outside of Finagle's stack.

   Used by Thrift and ThriftMux Client to facilitate giving the Finagle stack access to various data that are computed outside of Finagle's stack.

   This includes:

   • the deserialized forms of Thrift requests and responses.
   • the name of the rpc.
   • the elapsed time to serialize the request.
   • the elapsed time to deserialize the response.

   While this is thread-safe, it should only be used for the life of a single request/response pair.

   When using Scrooge for code generation, a proper ClientDeserializeCtx will be available to code via Contexts.local(ClientDeserializeCtx.Key).

   Note

   this class has evolved and it's name is now a bit too specific for its more expanded role.

2. class ClientIdRequiredFilter[Req, Rep] extends SimpleFilter[Req, Rep]

   

   A Filter for Thrift services that enforces all requests specify a com.twitter.finagle.thrift.ClientId.

3. abstract class GeneratedThriftService extends AnyRef

   

   An abstract class that all scrooge-generated thrift service objects inherit directly from, including services that extend other services.

4. case class InvalidThriftConnectionException() extends Exception with ServiceException with Product with Serializable

   

   Indicates that the connection on which a Thrift request was issued is invalid, where "validity" is determined by com.twitter.finagle.thrift.ValidateThriftService.

5. class MethodMetadata extends AnyRef

   

   Stores information about the current Thrift method.

   Stores information about the current Thrift method. This information is set in both Java and Scala generated code. It is expected that users will only need to interact with com.twitter.finagle.thrift.MethodMetadata.current to obtain the current MethodMetadata if it has been set.

   com.twitter.finagle.thrift.MethodMetadata.current

6. class NoClientIdSpecifiedException extends RequestException

   

   Indicates that a request without a com.twitter.finagle.thrift.ClientId was issued to a server that requires them.

   Indicates that a request without a com.twitter.finagle.thrift.ClientId was issued to a server that requires them. See com.twitter.finagle.thrift.ClientIdRequiredFilter for details.

7. class RichClientParam extends AnyRef

   

   Thrift-specific parameters for configuring clients.

8. case class RichServerParam(protocolFactory: TProtocolFactory = Thrift.param.protocolFactory, serviceName: String = "thrift", maxThriftBufferSize: Int = Thrift.param.maxThriftBufferSize, serverStats: StatsReceiver = LoadedStatsReceiver, responseClassifier: ResponseClassifier = ResponseClassifier.Default, perEndpointStats: Boolean = false) extends Product with Serializable

   

   Produce a server with params wrapped in RichServerParam

   Produce a server with params wrapped in RichServerParam

   protocolFactory

   A TProtocolFactory creates protocol objects from transports

   serviceName

   For server stats, (default: "thrift")

   maxThriftBufferSize

   The max size of a reusable buffer for the thrift response

   serverStats

   StatsReceiver for recording metrics

   responseClassifier

   See com.twitter.finagle.service.ResponseClassifier

   perEndpointStats

   Whether to record per-endpoint stats, (default: false). By enabling this, the specific Thrift Exceptions can be recorded. See PerEndpoint StatsFilter

9. class SeqIdFilter extends SimpleFilter[ThriftClientRequest, Array[Byte]]

   

   A Filter that overrides Thrift request sequence IDs, replacing them with our own randomly-assigned i32s.

   A Filter that overrides Thrift request sequence IDs, replacing them with our own randomly-assigned i32s. Upon response receipt, this filter ensures that responses have the correct corresponding sequence ID, failing any requests that do not.

   Note

   This only works when using BinaryProtocol.

10. case class SeqMismatchException(id: Int, expected: Int) extends TransportException with Product with Serializable

    

    Indicates that a Thrift response did not have the correct sequence ID according to that assigned by com.twitter.finagle.thrift.SeqIdFilter on the corresponding request.

11. final class ServerToReqRep extends (Array[Byte]) ⇒ ReqRep

    

    Used by Thrift and ThriftMux Server to facilitate giving the Finagle stack access to the deserialized forms of Thrift requests and responses.

12. trait ThriftClient extends AnyRef

    

    Stateless helper methods which wrap a given ServiceIface (deprecated) or a given ServicePerEndpoint with another type via the given method's implicit Builder.

13. class ThriftClientRequest extends AnyRef

    

14. case class ThriftMethodStats extends Product with Serializable

    

15. trait ThriftRichClient extends AnyRef

    

    A mixin trait to provide a rich Thrift client API.

16. trait ThriftRichServer extends AnyRef

    

    A mixin trait to provide a rich Thrift server API.

17. trait ThriftService extends AnyRef

    

    A marker trait that signifies that this is a thrift service that can be served by Finagle

18. trait ToThriftService extends AnyRef

    

    A trait that signifies a ThriftService can be created from this

19. class ValidateThriftService extends ServiceProxy[ThriftClientRequest, Array[Byte]]

    

    A filter that invalidates a connection if it suffers from an irrecoverable application exception.

    A filter that invalidates a connection if it suffers from an irrecoverable application exception.

    Amazingly, an Apache Thrift server will leave a connection in a bad state without closing it, and furthermore only expose such errors as an "application" exception.

    All we can do is sigh, pinch our noses, and apply ValidateThriftService.

20. final class DeserializeCtx[Rep] extends ClientDeserializeCtx[Rep]

    A typeclass to construct a MethodIface by wrapping a ServiceIface.
