Interface BatchingDescriptor<ElementT,ElementResultT,RequestT,ResponseT> (2.15.0)

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 BatchingDescriptor<String, String, List<String>, List<String>> {

   RequestBuilder<String, List<String>> newRequestBuilder(List<String> prototype) {
     return new RequestBuilder<String, List<String>>() {

       void add(String element) {
         list.add(element);
       }

       List<String> build() {
         return list.clone();
       }
     };
   }

   void splitResponse(List<String> callableResponse, List<SettableApiFuture<String>> batch) {
     for (int i = 0; i < batchresponse.size();="" i++)="" {="" batch.get(i).set(batchresponse.get(i);="" }="" }="" void="" splitexception(throwable="" throwable,="" list<settableapifuture<string>>="" batch)="" {="" for="" (settableapifuture<string>="" result="" :="" batch)="" {="" result.setexception(throwable);="" }="" }="" long="" countbytes(string="" element)="" {="" return="" element.length();="" }="" }="">

Returns the size of the passed element object in bytes.

Creates a new wrapper for the underlying request builder. It's used to pack the current batch request with elements.

Unpacks the batch response error into individual element errors.

Unpacks the batch response into individual elements results.
