Interface ConcurrencyTools.Shutdownable

Enclosing class:

ConcurrencyTools

public static interface ConcurrencyTools.Shutdownable

A Shutdownable is an execution resource than can be shutdown for termination.

Shutdownable is to execution resources as Closeable is to I/O resources.

This type is the result of applying the "Extract Interface" refactoring to the portion of ExecutorService concerned with shutdown and termination.
