Method Summary

Modifier and Type	Method	Description
<T> Unmarshaller<HttpRequest,T>	as(Unmarshaller<HttpRequest,T> um)	Returns the in-scope FromRequestUnmarshaller for the given type.
<T> scala.Function1<RequestContext,scala.concurrent.Future<RouteResult>>	completeWith(Marshaller<T,HttpResponse> marshaller, scala.Function1<scala.Function1<T,scala.runtime.BoxedUnit>,scala.runtime.BoxedUnit> inner)	Uses the marshaller for the given type to produce a completion function that is passed to its inner function.
<T> Directive<scala.Tuple1<T>>	entity(Unmarshaller<HttpRequest,T> um)	Unmarshalls the requests entity to the given type passes it to its inner Route.
<A, B> scala.Function1<RequestContext,scala.concurrent.Future<RouteResult>>	handleWith(scala.Function1<A,B> f, Unmarshaller<HttpRequest,A> um, Marshaller<B,HttpResponse> m)	Completes the request using the given function.

Method Details

entity

<T> Directive<scala.Tuple1<T>> entity(Unmarshaller<HttpRequest,T> um)

Unmarshalls the requests entity to the given type passes it to its inner Route. If there is a problem with unmarshalling the request is rejected with the Rejection produced by the unmarshaller.

Parameters:

um - (undocumented)

Returns:

(undocumented)

as

<T> Unmarshaller<HttpRequest,T> as(Unmarshaller<HttpRequest,T> um)

Returns the in-scope FromRequestUnmarshaller for the given type.

Parameters:

um - (undocumented)

Returns:

(undocumented)

completeWith

<T>
scala.Function1<RequestContext,scala.concurrent.Future<RouteResult>> completeWith(Marshaller<T,HttpResponse> marshaller,
 scala.Function1<scala.Function1<T,scala.runtime.BoxedUnit>,scala.runtime.BoxedUnit> inner)

Uses the marshaller for the given type to produce a completion function that is passed to its inner function. You can use it do decouple marshaller resolution from request completion.

Parameters:

marshaller - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

instanceOf

<T> Marshaller<T,HttpResponse> instanceOf(Marshaller<T,HttpResponse> m)

Returns the in-scope Marshaller for the given type.

Parameters:

m - (undocumented)

Returns:

(undocumented)

handleWith

<A,
B>
scala.Function1<RequestContext,scala.concurrent.Future<RouteResult>> handleWith(scala.Function1<A,B> f,
 Unmarshaller<HttpRequest,A> um,
 Marshaller<B,HttpResponse> m)

Completes the request using the given function. The input to the function is produced with the in-scope entity unmarshaller and the result value of the function is marshalled with the in-scope marshaller.

Parameters:

f - (undocumented)

um - (undocumented)

m - (undocumented)

Returns:

(undocumented)
