Class ObjectWithDefaultStringImplConverter

java.lang.Object

org.apache.brooklyn.util.core.xstream.ObjectWithDefaultStringImplConverter

All Implemented Interfaces:

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

public class ObjectWithDefaultStringImplConverter
extends java.lang.Object
implements com.thoughtworks.xstream.converters.Converter

A converter that delegates to ConverterLookup.lookupConverterForType(Class), where possible. On unmarshalling, if there is no class attribute then it assumes that the type must be a String. This is useful if a class has its field changed from type String to Object. The old persisted state will look like <mykey>myval</mykey>, rather than <mykey class="string">myval</mykey>. Use this converter by annotation the field with @XStreamConverter(ObjectWithDefaultStringImplConverter.class). One must also call xstream.processAnnotations(MyClazz.class) to ensure the annotation is actually parsed.
