Class TestTransport.SwitchableLoggedBehavior<A,B>

java.lang.Object
  extended by akka.remote.transport.TestTransport.SwitchableLoggedBehavior<A,B>
All Implemented Interfaces:
scala.Function1<A,scala.concurrent.Future<B>>
Enclosing class:
TestTransport

public static class TestTransport.SwitchableLoggedBehavior<A,B>
extends java.lang.Object
implements scala.Function1<A,scala.concurrent.Future<B>>

Test utility to make behavior of functions that return some Future[B] controllable from tests. This tool is able to overwrite default behavior with any generic behavior, including failure, and exposes control to the timing of the completition of the returned future.

The utility is implemented as a stack of behaviors, where the behavior on the top of the stack represents the currently active behavior. The bottom of the stack always contains the defaultBehavior which can not be popped out.

param: defaultBehavior The original behavior that might be overwritten. It is always possible to restore this behavior

param: logCallback Function that will be called independently of the current active behavior

Constructor Detail

TestTransport.SwitchableLoggedBehavior

public TestTransport.SwitchableLoggedBehavior(scala.Function1<A,scala.concurrent.Future<B>> defaultBehavior,
                                              scala.Function1<A,scala.runtime.BoxedUnit> logCallback)
Method Detail

push

public void push(scala.Function1<A,scala.concurrent.Future<B>> behavior)
Changes the current behavior to the provided one.

Parameters:
behavior - Function that takes a parameter type A and returns a Future[B].

pushConstant

public void pushConstant(B c)
Changes the behavior to return a completed future with the given constant value.

Parameters:
c - The constant the future will be completed with.

pushError

public void pushError(java.lang.Throwable e)
Changes the current behavior to return a failed future containing the given Throwable.

Parameters:
e - The throwable the failed future will contain.

pushDelayed

public scala.concurrent.Promise<scala.runtime.BoxedUnit> pushDelayed()
Enables control of the completion of the previously active behavior. Wraps the previous behavior in a new one, returns a control promise that starts the original behavior after the control promise is completed.

Returns:
A promise, which delays the completion of the original future until after this promise is completed.

pop

public void pop()
Restores the previous behavior.


apply

public scala.concurrent.Future<B> apply(A params)
Applies the current behavior, and invokes the callback.

Specified by:
apply in interface scala.Function1<A,scala.concurrent.Future<B>>
Parameters:
params - The parameters of this behavior.
Returns:
The result of this behavior wrapped in a future.
