Interface AsyncCloseable

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 AsyncCloseable

An object that may hold resources that must be explicitly released, and the release operation should be performed asynchronously.

Examples of such resources are database connections, open file handles, socket descriptors etc. While similar to AutoCloseable, this interface should be used when the resource release operation may possibly be asynchronous. For example, if an object is thread-safe and has many consumers, an implementation may require all current ongoing operations to complete before resources are relinquished.

May be used with the methods Promises.tryApplyEx(CompletionStage, Function), Promises.tryComposeEx(Promise, Function) to emulate the behavior of a try with resources block.

Method Summary
