Type Members

  1. trait BoundHandler[-In] extends HandlerWrite[In]

    A Handler which has been bound to some "downstream" receiver of outputs, so that the push and finish methods will delegate to that downstream rather than requiring a downstream receiver to be passed as a method parameter.

    A Handler which has been bound to some "downstream" receiver of outputs, so that the push and finish methods will delegate to that downstream rather than requiring a downstream receiver to be passed as a method parameter.

    In

    The handler's input type

  2. trait Handler[-In, +Out] extends AnyRef

    An internally-mutable "handler" that performs a Transformer's input/output logic.

  3. trait HandlerLinkage[+Out] extends AnyRef

    Specialization for a BoundHandler whose "downstream" can be changed at will.

    Specialization for a BoundHandler whose "downstream" can be changed at will.

    Out

    The handler's output type

  4. trait HandlerWrite[-Out] extends AnyRef

    Represents the "downstream" of a handler.

    Represents the "downstream" of a handler. Whenever a handler is told to push or finish, it uses a HandlerWrite to receive its output. A HandlerWrite could be an object that collects the values to a buffer which you can manually inspect later (see BoundHandler.ToBuilder), or a wrapper around some secondary Handler i.e. the next transformation step.

    Out

    The output event type from the upstream handler, which acts as the input to this receiver

  5. trait Stateless[-In, +Out] extends Transformer[In, Out] with Handler[In, Out]

    A stateless transformer acts as its own handler

    A stateless transformer acts as its own handler

    In

    The incoming event type

    Out

    The outgoing event type

  6. implicit final class TransformerKVParsingOps[In, K, V] extends AnyVal

    Extra methods for transformers whose Out type is a Tuple2

  7. implicit final class TransformerParsingOps[In, A] extends AnyVal

    Extra transformer methods that had to be defined separately from the trait due to either In or Out needing to be invariant.

  4. def apply[In]: TransformerApplyWithBoundInput[In]

    Convenience for creating transformers whose input type is bound to In.

    Convenience for creating transformers whose input type is bound to In.

    This is particularly nice when the Out type can be inferred by the compiler, e.g.

    Transformer[Int].op(i => Emit.one(i * 2))
// versus
Transformer.op[Int, Int](i => Emit.one(i * 2))
