How to avoid writing many wrappers for identical library methods that do not implement a common interface?

I am working with the AWS SDK for Java, which has a large number of classes that contain common methods, however the common methods do not implement a common interface (or extend from a common base class, etc.)

For instance, I have to write this pattern very frequently:

while(true) {
  InformationResult result = client.getInformation(new InformationRequest());
  CustomData data = result.getData(); 
  // do stuff
  if ! result.isTruncated() {
   break;
  }
}

I would like to only write this pattern once, however there are many CustomData and InformationResult classes with no polymorphic relation.

Ideas? I'd like not to wrap all the classes myself.
