Interface ShutdownAwareCallable<V>

Type Parameters:

V - the result type of method call

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ShutdownAwareCallable<V>

A task that returns a result and may throw an exception. Implementors define a single method called call with ShutdownInfo as an argument.

The ShutdownAwareCallable interface is similar to Callable, in that both are designed for classes whose instances are potentially executed by another thread. A ShutdownAwareCallable however has an input argument ShutdownInfo which can be asked if underlying Executor has received a shutdown signal.

The class is intended to be use with custom executor wrapper Runner.
