Package com.alibaba.ttl

Class TtlRecursiveTask<V>

java.lang.Object

java.util.concurrent.ForkJoinTask<V>

com.alibaba.ttl.TtlRecursiveTask<V>

All Implemented Interfaces:

TtlEnhanced, Serializable, Future<V>

public abstract class TtlRecursiveTask<V>
extends ForkJoinTask<V>
implements TtlEnhanced

A recursive result-bearing ForkJoinTask enhanced by TransmittableThreadLocal.

Recommend to use TtlAgent; Specially for Java 8 Stream and CompletableFuture, these async task are executed by ForkJoinPool via ForkJoinTask at the bottom.

Since:

2.4.0
