Package org.hawaiiframework.async

Class DelegatingExecutor

java.lang.Object

org.hawaiiframework.async.DelegatingExecutor

All Implemented Interfaces:

Executor, org.springframework.core.task.AsyncListenableTaskExecutor, org.springframework.core.task.AsyncTaskExecutor, org.springframework.core.task.TaskExecutor, org.springframework.scheduling.SchedulingTaskExecutor

public class DelegatingExecutor
extends Object
implements org.springframework.core.task.AsyncListenableTaskExecutor, org.springframework.scheduling.SchedulingTaskExecutor

Task executor that delegates to the task executor configured for a task.

In addition to the delegate, the async configuration properties and the task name is stored, so we know which task this executor is for and we are able to determine the timeout.

Since:

2.0.0
