Class RobustReflectionConverter

java.lang.Object
  hudson.util.RobustReflectionConverter

All Implemented Interfaces:

com.thoughtworks.xstream.converters.Converter, com.thoughtworks.xstream.converters.ConverterMatcher

public class RobustReflectionConverter
extends Object
implements com.thoughtworks.xstream.converters.Converter

Custom ReflectionConverter that handle errors more gracefully.

• If the field is missing, the value is ignored instead of causing an error. This makes evolution easy.
• If the type found in XML is no longer available, the element is skipped instead of causing an error.
