RequestFutureTarget (glide 3.8.0 API)

java.lang.Object
- com.bumptech.glide.request.RequestFutureTarget<T,R>

Type Parameters:
T - The type of the data to load.
R - The type of the resource that will be loaded.

All Implemented Interfaces:

LifecycleListener, FutureTarget<R>, Target<R>, Runnable, Future<R>
```
public class RequestFutureTarget<T,R>
extends Object
implements FutureTarget<R>, Runnable
```
A Future implementation for Glide that can be used to load resources in a blocking manner on background threads.
Note - Unlike most targets, RequestFutureTargets can be used once and only once. Attempting to reuse a RequestFutureTarget will probably result in undesirable behavior or exceptions. Instead of reusing objects of this class, the pattern should be:
```
     RequestFutureTarget target = Glide.load("")...
     Object resource = target.get();
     // Do something with resource, and when finished:
     Glide.clear(target);
     
     
```
The Glide.clear(FutureTarget) call will make sure any resources used are recycled.
