#SCALA FUTURE CODE#

When this future is completed with a failure (i.e., with a throwable),Īpply the provided callback to the throwable. Only used to accept any return type of the given PartialFunction pfĪ PartialFunction which will be conditionally applied to the outcome of this Future returnsĪ Future which will be completed with the exact same outcome as this Future but after the PartialFunction has been executed.Ĭast the receiver object to be of type T0. Since this method executes asynchronously and does not produce a return value,Īny non-fatal exceptions thrown will be reported to the ExecutionContext. Or class M圜lass(myParam: MyType)( implicit ec: ExecutionContext) Ĭase r => sys.error( 'runtime exception') Request one from the caller by adding an implicit parameter list: def myMethod(myParam: MyType)( implicit ec: ExecutionContext) = …

#SCALA FUTURE CODE#

If the code in question is a class or method definition, and no ExecutionContext is available, The general advice for these implicits are as follows. When using things like Futures, it is often required to have an implicit ExecutionContext When working with Futures, you will often find that importing the whole concurrent GuideĪ more detailed guide to Futures and Promises, including discussion and examples This package object contains primitives for concurrent and parallel programming. For example, on the JVM, String is an alias for. Other aliases refer to classes provided by the underlying platform. Some of these identifiers are type aliases provided as shortcuts to commonly used classes. Identifiers in the scala package and the scala.Predef object are always in scope by default.
