JavaFutures

trait JavaFutures extends Futures

Provides an implicit conversion from java.util.concurrent.Future[T] to FutureConcept[T].

This trait enables you to invoke the methods defined on FutureConcept on a Java Future, as well as to pass a Java future to the whenReady methods of supertrait Futures. See the documentation for supertrait Futures for the details on the syntax this trait provides for testing with Java futures.

  8. implicit def convertJavaFuture[T](javaFuture: Future[T]): FutureConcept[T]

    Implicitly converts a java.util.concurrent.Future[T] to FutureConcept[T], allowing you to invoke the methods defined on FutureConcept on a Java Future, as well as to pass a Java future to the whenReady methods of supertrait Futures.

    See the documentation for supertrait Futures for the details on the syntax this trait provides for testing with Java futures.

    If the get method of the underlying Java future throws java.util.concurrent.ExecutionException, and this exception contains a non-null cause, that cause will be included in the TestFailedException as its cause. The ExecutionException will be be included as the TestFailedException's cause only if the ExecutionException's cause is null.

    The isExpired method of the returned FutureConcept will always return false, because the underlying type, java.util.concurrent.Future, does not support the notion of a timeout. The isCanceled method of the returned FutureConcept will return the result of invoking isCancelled on the underlying java.util.concurrent.Future.

  20. final def scaled(span: Span): Span

    Scales the passed Span by the Double factor returned by spanScaleFactor.

    Scales the passed Span by the Double factor returned by spanScaleFactor.

    The Span is scaled by invoking its scaledBy method, thus this method has the same behavior: The value returned by spanScaleFactor can be any positive number or zero, including a fractional number. A number greater than one will scale the Span up to a larger value. A fractional number will scale it down to a smaller value. A factor of 1.0 will cause the exact same Span to be returned. A factor of zero will cause Span.ZeroLength to be returned. If overflow occurs, Span.Max will be returned. If underflow occurs, Span.ZeroLength will be returned.

  21. def spanScaleFactor: Double

    The factor by which the scaled method will scale Spans.

    The factor by which the scaled method will scale Spans.

    The default implementation of this method will return the span scale factor that was specified for the run, or 1.0 if no factor was specified. For example, you can specify a span scale factor when invoking ScalaTest via the command line by passing a -F argument to Runner.

  28. final def whenReady[T, U](future: FutureConcept[T])(fun: (T) ⇒ U)(implicit config: PatienceConfig): U

    Queries the passed future repeatedly until it either is ready, or a configured maximum amount of time has passed, sleeping a configured interval between attempts; and when ready, passes the future's value to the passed function.

    Queries the passed future repeatedly until it either is ready, or a configured maximum amount of time has passed, sleeping a configured interval between attempts; and when ready, passes the future's value to the passed function.

    The maximum amount of time in milliseconds to tolerate unsuccessful attempts before giving up is configured by the timeout field of the PatienceConfig passed implicitly as the last parameter. The interval to sleep between attempts is configured by the interval field of the PatienceConfig passed implicitly as the last parameter.

    If the eitherValue method of the underlying Scala future returns a scala.Some containing a scala.util.Failure containing a java.util.concurrent.ExecutionException, and this exception contains a non-null cause, that cause will be included in the TestFailedException as its cause. The ExecutionException will be be included as the TestFailedException's cause only if the ExecutionException's cause is null.
