Syntax
public class ConditionalPutAll : AbstractProcessor, IEntryProcessor, IPortableObject
Remarks

Obviously, using more specific, fine-tuned filters may provide additional flexibility and efficiency allowing the multi-put operations to be performed conditionally on values of specific attributes (or even calculations) instead of a simple existence check.
