public interface BatchingDescriptor<ElementT,ElementResultT,RequestT,ResponseT>An adapter that packs and unpacks the elements in and out of batch requests and responses.
This interface should be implemented by either a service specific client or autogenerated by gapic-generator.
Example implementation:
class ListDescriptor implements BatchingDescriptorType Parameters
| Name | Description |
| ElementT | |
| ElementResultT | |
| RequestT | |
