All Implemented Interfaces:

Serializer

public class DBObjectXStreamSerializer
extends AbstractXStreamSerializer

XStream based serializer implementation that serializes objects into a Binary JSON structure. This serializer is originally meant for use with a MongoDB based Event Store. It escapes BSON Node names to prevent them containing periods (".").

Since:

2.0

Constructor Detail

DBObjectXStreamSerializer

public DBObjectXStreamSerializer()

Initialize the serializer with UTF-8 character set and a default XStream serializer.

An AnnotationRevisionResolver is used to resolve revision for serialized objects.

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(com.thoughtworks.xstream.XStream xStream)

Initialize the serializer using the UTF-8 character set. The provided XStream instance is used to perform the serialization.

An AnnotationRevisionResolver is used to resolve the revision for serialized objects.

Parameters:

xStream - XStream instance to use

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(com.thoughtworks.xstream.XStream xStream,
                         RevisionResolver revisionResolver)

Initialize the serializer using the UTF-8 character set. The provided XStream instance is used to perform the serialization, while the given revisionResolver is used to resolve the revision of the serialized object.

Parameters:

xStream - The XStream instance to serialize objects with

revisionResolver - The instance to resolve revisions with

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(Charset charset)

Initialize the serializer using the given charset. A default XStream instance (with XppDriver) is used to perform the serialization.

An AnnotationRevisionResolver is used to resolve the revision for serialized objects.

Parameters:

charset - The character set to use

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(Charset charset,
                         com.thoughtworks.xstream.XStream xStream)

Initialize the serializer using the given charset and xStream instance. The xStream instance is configured with several converters for the most common types in Axon.

An AnnotationRevisionResolver is used to resolve the revision for serialized objects.

Parameters:

charset - The character set to use

xStream - The XStream instance to use

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(Charset charset,
                         com.thoughtworks.xstream.XStream xStream,
                         RevisionResolver revisionResolver)

Initialize the serializer using the given charset, xStream and revisionResolver instance. The xStream instance is configured with several converters for the most common types in Axon.

Parameters:

charset - The character set to use

xStream - The XStream instance to use

revisionResolver - The instance to resolve revisions with

DBObjectXStreamSerializer

public DBObjectXStreamSerializer(Charset charset,
                         com.thoughtworks.xstream.XStream xStream,
                         RevisionResolver revisionResolver,
                         ConverterFactory converterFactory)

Initialize the serializer using the given charset and xStream instance. The given converterFactory instance is used to convert between serialized representation types.

Parameters:

charset - The character set to use

xStream - The XStream instance to use

revisionResolver - The strategy to use to resolve the revision of an object

converterFactory - The converter factory to provide the converters

Method Detail

registerConverters

protected void registerConverters(ChainingConverterFactory converterFactory)

Description copied from class: AbstractXStreamSerializer

Registers any converters that are specific to the type of content written by this serializer.

Specified by:

registerConverters in class AbstractXStreamSerializer

Parameters:

converterFactory - the ConverterFactory to register the converters with

doSerialize

protected <T> T doSerialize(Object object,
                Class<T> expectedFormat,
                com.thoughtworks.xstream.XStream xStream)

Description copied from class: AbstractXStreamSerializer

Serialize the given object to the given expectedFormat. The subclass may use AbstractXStreamSerializer.convert(Class, Class, Object) to convert the result of the serialization to the expected type.

Specified by:

Description copied from class: AbstractXStreamSerializer

Deserialize the given serializedObject.

Specified by:

doDeserialize in class AbstractXStreamSerializer

Parameters:

serializedObject - The instance containing the serialized format of the object

xStream - The XStream instance to deserialize with

Returns:

the deserialized object
