封闭类:

ConcurrentHashMapV8<K,V>
```
public static class ConcurrentHashMapV8.ForkJoinTasks
extends Object
```
Predefined tasks for performing bulk parallel operations on ConcurrentHashMapV8s. These tasks follow the forms and rules used for bulk operations. Each method has the same name, but returns a task rather than invoking it. These methods may be useful in custom applications such as submitting a task without waiting for completion, using a custom pool, or combining with other tasks.
