object TryAll
An extension to the scala.util.Try
interface to support aggregated try operations.
This API extends Scala's Try
to support situations where you have Try[_ <: Iterable[_]]
and want to attempt an
operation on all elements of the Iterable
contained in the Try
and flatten the results of those operations into
a single Try
.
This API provides two mechanisms by which you can attempt operations on aggregations:
(_: Try[_ <: Iterable[_]]).onEach
exposes combinators that will *fail fast*, meaning that it will apply a function to each member of the aggregate and will abort immediately if it encounters a failure on any member.(_: Try[_ <: Iterable[_]]).onEvery
exposes combinators that will *fail eventually*, meaning that it will apply a function to every member of the aggregate, collecting any failures it encounters and returning them after all elements have been processed.
Additionally, this API extends scala.util.Failure
with two new failure abstractions:
Problem
provides a factory and extractor for failures that carry only a message and no stack trace.Failures
provides a factory and extractor for failures that are only aggregations of other failures.
