Class AsyncScheduler

java.lang.Object

oracle.javatools.parser.util.AsyncScheduler

public class AsyncScheduler
extends java.lang.Object

The AsyncScheduler is a part of a basic API to allow scheduling asynchronous tasks that support cancelling while the task is running. It is recommended that JSR 166 be used when it becomes available as part of the JDK later.

This scheduler schedules background threads to complete queued tasks. If there are no tasks queued, the background threads will exit.
