Class NullAsEmptyBodyProtocolRequestMarshaller<OrigRequestT>

java.lang.Object

software.amazon.awssdk.core.internal.protocol.json.NullAsEmptyBodyProtocolRequestMarshaller<OrigRequestT>

Type Parameters:

OrigRequestT - Type of the original request object.

All Implemented Interfaces:

ProtocolMarshaller, ProtocolRequestMarshaller<OrigRequestT>

public class NullAsEmptyBodyProtocolRequestMarshaller<OrigRequestT>
extends Object
implements ProtocolRequestMarshaller<OrigRequestT>

AWS services expect an empty body when the payload member is null instead of an explicit JSON null. This implementation can be removed once CR-6541513 has been deployed to all services that use the payload trait.
