The result of a batch operation. The result status is successful if and only if all results
are successful. Individual results can be retrieved using
public Status getStatus ()
Certain errors are due to failures that can be resolved by launching a particular intent.
The resolution intent is available via
public R take (BatchResultToken<R> resultToken)
Retrieves a result from the batch.
After the result has been retrieved, it is an error to attempt to retrieve it again. It is
the responsibility of the caller to release any resources associated with the returned
result. Some result types may implement
Releasable, in which case
release() should be used to free the associated resources.
