Class GapAwareTrackingTokenConverter

java.lang.Object

com.thoughtworks.xstream.converters.collections.AbstractCollectionConverter

com.thoughtworks.xstream.converters.collections.CollectionConverter

org.axonframework.serialization.GapAwareTrackingTokenConverter

All Implemented Interfaces:

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

public final class GapAwareTrackingTokenConverter
extends com.thoughtworks.xstream.converters.collections.CollectionConverter

Dedicated CollectionConverter implementation to de-/serializer the GapAwareTrackingToken and org.axonframework.eventsourcing.eventstore.GapAwareTrackingToken.

Necessary due to the ConcurrentSkipListSet used within the GapAwareTrackingToken, as XStream is incapable to marshall / unmarshall these Collections from the java.util.concurrent package. In pre-JDK16 times, XStream would use the com.thoughtworks.xstream.converters.reflection.ReflectionConverter for this.

Since:

4.7.0
