I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Use another library that supports both reflection like XStream and code generation.

Therefore we have to use either a custom converter that transforms this list into a single string or we use for simplicity a simple string here:. Note, that no XStreamAsAttribute annotations were necessary.

The converter assumes it implicitly. Sometimes a class may contain elements that should not be part of the resulting XML. In our case we may now drop the 'messageType', since we are only interested at the content. This is easy using the XStreamOmitField annotation:. Until now we have always told you, that you have to call processAnnotation to configure the XStream instance with the present annotations in the different classes.

However, this is only half the truth. You can run XStream also in a lazy mode, where it auto-detects the annotations while processing the object graph and configure the XStream instance on-the-fly:.

The resulting XML will look as expected! Nevertheless you have to understand the implications, therefore some words of warning:. An XStream instance caches all class types processed for annotations. Every time XStream converts an object it will in auto-detection mode first process the object's type and all the types related as explained above.

Therefore it is no problem to serialize an object graph into XML, since XStream will know of all types in advance. This is no longer true at deserialization time.

XStream has to know the alias to turn it into the proper type, but it can find the annotation for the alias only if it has processed the type in advance. Therefore deserialization will fail if the type has not already been processed either by having called XStream's processAnnotations method or by already having serialized this type.

However, XStreamAlias is the only annotation that may fail in this case. XStream is not thread-safe while it is configured, thread-safety is only guaranteed during marshalling and unmarshalling. Unfortunately an annotation is defining a change in configuration that is now applied while object marshalling is processed. Therefore will the auto-detection mode turn XStream's marshalling process in a thread-unsafe operation.

ShortConverter short java. Throwable java. Exception java. RuntimeException java. It retains the full stack trace, including that of any nested exceptions. The stack trace elements are handled by the StackTraceElementConverter.

Enum The Converter must be initialized with an Enum type and an optional mapping between strings and enum values. By default it will use the Enum's string representation as value. Available with Java 1. Must be registered explicitly for the Enum type or locally. ArrayList java.

LinkedList java. HashSet java. Vector java. Can be registered for an individual Collection type or locally, suppression of implicit type might be necessary. HashMap java. Hashtable java. LinkedHashMap java. Can be registered for an individual Map type or locally, suppression of implicit type might be necessary.

Should be registered locally or for an individual Collection type. NamedMapConverter java. If key or value are written as attributes or if the value is written as text of the entry element, those types must be handled by a SingleValueConverter.

Should be registered locally or for an individual Map type. PropertiesConverter java. Comparator associated with the TreeMap. Comparator associated with the TreeSet. Designed to be readable without taking up too much space.

Calendar java. Implementation needs joda-time for JDK 1. LocaleConverter java. ZoneId java. ZoneOffset java. Serializable See description at Generalized Converters. Can be registered with Mapper globally or locally to respect type aliases. Method java.
