Class SubjectConverter

java.lang.Object

com.thoughtworks.xstream.converters.collections.AbstractCollectionConverter

com.thoughtworks.xstream.converters.extended.SubjectConverter

All Implemented Interfaces:

Converter, ConverterMatcher

public class SubjectConverter
extends AbstractCollectionConverter

Converts a Subject instance. Note, that this Converter does only convert the contained Principals as it is done by JDK serialization, but not any credentials. For other behaviour you can derive your own converter, overload the appropriate methods and register it in the XStream.

Since:

1.1.3
