Method Detail

serialize

public Data<byte[]> serialize(Object object)

Description copied from interface: Serializer

Serializes an object to a Data object containing a byte array.

Specified by:

serialize in interface Serializer

Parameters:

object - The instance to serialize

Returns:

Data object containing byte array representation of the object

getObjectType

protected String getObjectType(Object object)

getRevision

protected Revision getRevision(Object object)

doSerialize

protected abstract byte[] doSerialize(Object object)
                               throws Exception

Throws:

Exception

deserialize

public <S extends SerializedObject<byte[],S>> Stream<DeserializingObject<byte[],S>> deserialize(Stream<S> dataStream,
                                                                                                            boolean failOnUnknownType)

Description copied from interface: Serializer

Upcasts and deserializes a stream of serialized objects. Each result in the output stream contains both a provider for the deserialized object and the serialized object after upcasting that is used as the source of the deserialized object.

Deserialization is performed lazily. This means that actual conversion for a given result in the output stream only happens if DeserializingObject.getPayload() is invoked on the result. This has the advantage that a caller can inspect what type will be returned via DeserializingObject.getSerializedObject() before deciding to go through with the deserialization.

You can specify whether deserialization of a result in the output stream should fail with a SerializationException if a type is unknown (not a class). It is up to the implementation to determine what should happen if a type is unknown but the failOnUnknownType flag is false.

Specified by:

deserialize in interface Serializer

Type Parameters:

S - the type of the serialized object

Parameters:

dataStream - data input stream to deserialize

failOnUnknownType - flag that determines whether deserialization of an unknown type should give an exception

Returns:

a stream containing deserialization results
