ComputeTaskFuture (Ignite 2.17.0)

Type Parameters:

R - Type of the task result returning from ComputeTask.reduce(List) method.

All Superinterfaces:

IgniteFuture<R>
```
public interface ComputeTaskFuture<R>
extends IgniteFuture<R>
```
This class defines a handler for asynchronous task execution. It's similar in design to standard JDK Future interface but has improved and easier to use exception hierarchy.

Modifier and Type	Method	Description
`R`	`get()`	Synchronously waits for completion of the computation and returns computation result.
`R`	`get(long timeout, TimeUnit unit)`	Synchronously waits for completion of the computation for up to the timeout specified and returns computation result.
