object ScalaFutures extends ScalaFutures
Companion object that facilitates the importing of ScalaFutures
members as
an alternative to mixing in the trait. One use case is to import ScalaFutures
's members so you can use
them in the Scala interpreter.

Futures
for the details on the syntax this trait provides for testing with Java futures.If the
eitherValue
method of the underlying Scala future returns ascala.Some
containing ascala.util.Failure
containing ajava.util.concurrent.ExecutionException
, and this exception contains a non-null
cause, that cause will be included in theTestFailedException
as its cause. TheExecutionException
will be be included as theTestFailedException
's cause only if theExecutionException
's cause isnull
.The
isExpired
method of the returnedFutureConcept
will always returnfalse
, because the underlying type,scala.concurrent.Future
, does not support the notion of expiration. Likewise, theisCanceled
method of the returnedFutureConcept
will always returnfalse
, because the underlying type,scala.concurrent.Future
, does not support the notion of cancelation.- scalaFuture

.Scales the passed
Span
by theDouble
factor returned byspanScaleFactor
.The
Span
is scaled by invoking itsscaledBy
method, thus this method has the same behavior: The value returned byspanScaleFactor
can be any positive number or zero, including a fractional number. A number greater than one will scale theSpan
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 sameSpan
to be returned. A factor of zero will causeSpan.ZeroLength
to be returned. If overflow occurs,Span.Max
will be returned. If underflow occurs,Span.ZeroLength
will be returned.- Definition Classes
