    Description copied from interface: Call
    
    Executes the call until a successful result is returned or the configured policies are exceeded.
    
    Specified by:
    
    execute in interface Call<R>
  - cancel
```
public boolean cancel(boolean mayInterruptIfRunning)
```
    Description copied from interface: Call
    
    Cancels a synchronous execution and calls the most recent cancelCallback that was registered. The execution is still allowed to complete and return a result. In addition to using a cancelCallback, executions can cooperate with cancellation by checking ExecutionContext.isCancelled().
    
    Specified by:
    
    cancel in interface Call<R>
    
    Parameters:
    
    mayInterruptIfRunning - whether the execution should be interrupted
    
    Returns:
    
    whether cancellation was successful or not. Returns false if the execution was already cancelled or completed.
  - isCancelled
```
public boolean isCancelled()
```
    Description copied from interface: Call
    
    Returns whether the call has been cancelled.
    
    Specified by:
    
    isCancelled in interface Call<R>
