Class JavaSerializer

java.lang.Object

org.axonframework.serialization.JavaSerializer

All Implemented Interfaces:

Serializer

Deprecated.

in favor of the XStreamSerializer and JacksonSerializer, as direct Java serialization is relatively error prone. We hence strongly encourage to use either the XStream or Jackson solution in favor of this Serializer implementation.

@Deprecated
public class JavaSerializer
extends Object
implements Serializer

Serializer implementation that uses Java serialization to serialize and deserialize object instances. This implementation is very suitable if the life span of the serialized objects allows classes to remain unchanged. If Class definitions need to be changed during the object's life cycle, another implementation, like the XStreamSerializer might be a more suitable alternative.

Constructor Detail

JavaSerializer

protected JavaSerializer(JavaSerializer.Builder builder)

Deprecated.

Instantiate a JavaSerializer based on the fields contained in the JavaSerializer.Builder.

Parameters:

builder - the JavaSerializer.Builder used to instantiate a JavaSerializer instance

Method Detail

builder

public static JavaSerializer.Builder builder()

Deprecated.

Instantiate a Builder to be able to create a JavaSerializer.

The RevisionResolver is defaulted to an SerialVersionUIDRevisionResolver.

Returns:

a Builder to be able to create a JavaSerializer

serialize

public <T> SerializedObject<T> serialize(Object instance,
                                         @Nonnull
                                         Class<T> expectedType)

Deprecated.

Description copied from interface: Serializer

Serialize the given object into a Serialized Object containing the given expectedRepresentation.

Use Serializer.canSerializeTo(Class) to detect whether the expectedRepresentation is supported by this serializer.

Specified by:

serialize in interface Serializer

Type Parameters:

T - The expected data type representing the serialized object

Parameters:

instance - The object to serialize

expectedType - The expected data type representing the serialized object

Returns:

the instance representing the serialized object.

canSerializeTo

public <T> boolean canSerializeTo(@Nonnull
                                  Class<T> expectedRepresentation)

Deprecated.

Description copied from interface: Serializer

Indicates whether this Serializer is capable of serializing to the given expectedRepresentation.

When true, this does *not* guarantee that the serialization and (optional) conversion will also succeed when executed. For example, when a serializer produces a byte[] containing JSON, trying to convert to a Dom4J Document will fail, even though this serializer has a converter to convert byte[] to Dom4J instances.

Specified by:

canSerializeTo in interface Serializer

Type Parameters:

T - The type of data a Serialized Object should contain

Parameters:

expectedRepresentation - The type of data a Serialized Object should contain

Returns:

true if the expectedRepresentation is supported, otherwise false.

deserialize

public <S,T> T deserialize(@Nonnull
                           SerializedObject<S> serializedObject)

Deprecated.

Description copied from interface: Serializer

Deserializes the first object read from the given bytes. The bytes are not consumed from the array or modified in any way. The resulting object instance is cast to the expected type.

Specified by:

deserialize in interface Serializer

Type Parameters:

S - The data type of the serialized object

T - The expected deserialized type

Parameters:

serializedObject - the instance describing the type of object and the bytes providing the serialized data

Returns:

the serialized object, cast to the expected type

classForType

public Class classForType(@Nonnull
                          SerializedType type)

Deprecated.

Description copied from interface: Serializer

Returns the class for the given type identifier. The result of this method must guarantee that the deserialized SerializedObject with the given type is an instance of the returned Class.

If a class cannot be resolved (i.e. because the class is not available on this JVM's classpath) this method returns an UnknownSerializedType instance which proides access to the raw underlying data.

Specified by:

classForType in interface Serializer

Parameters:

type - The type identifier of the object

Returns:

the Class representing the type of the serialized Object

typeForClass

public SerializedType typeForClass(Class type)

Deprecated.

Description copied from interface: Serializer

Returns the type identifier for the given class. This is the type identifier of the Serialized object as returned by Serializer.serialize(Object, Class).

Specified by:

typeForClass in interface Serializer

Parameters:

type - Class representing the type of the serializable Object.

Returns:

The type identifier of the object

getConverter

public Converter getConverter()

Deprecated.

Description copied from interface: Serializer

Returns the Converter used by this Serializer to convert between serialized representations. Generally, this Converter depends on the type of data the serializer serializes to.

Specified by:

getConverter in interface Serializer

Returns:

the converter used by this Serializer
