TtlRecursiveTask (TransmittableThreadLocal(TTL) 2.12.1 API)

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
