AsyncResponseHandler (AWS Java SDK :: SDK Core 2.23.20 API)

java.lang.Object
- software.amazon.awssdk.core.internal.http.async.AsyncResponseHandler<T>

Type Parameters:

T - Type that the response handler produces.

All Implemented Interfaces:

TransformingAsyncResponseHandler<T>, SdkAsyncHttpResponseHandler
```
public final class AsyncResponseHandler<T>
extends Object
implements TransformingAsyncResponseHandler<T>
```
Response handler for asynchronous non-streaming operations.
Adapts an HttpResponseHandler to the asynchronous TransformingAsyncResponseHandler. Buffers all content into a ByteArrayInputStream then invokes the HttpResponseHandler.handle(software.amazon.awssdk.http.SdkHttpFullResponse, software.amazon.awssdk.core.interceptor.ExecutionAttributes) method.

    Return the future holding the transformed response.
    This method is guaranteed to be called before the request is executed, and before SdkAsyncHttpResponseHandler.onHeaders(software.amazon.awssdk.http.SdkHttpResponse) is signaled.
    
    Specified by:
    
    prepare in interface TransformingAsyncResponseHandler<T>
    
    Returns:
    
    The future holding the transformed response.
