Returns:

the name of this serializer.

isSerializationTextBased

protected boolean isSerializationTextBased()

Description copied from class: AbstractObjectValueSerializer

Return true if the serialization is text based. Return false otherwise

Specified by:

isSerializationTextBased in class AbstractObjectValueSerializer

getTypeNameForDeserialized

Specified by:

getTypeNameForDeserialized in class AbstractObjectValueSerializer

Parameters:

deserializedObject - . Guaranteed not to be null

Returns:

the type name fot the object.

serializeToByteArray

protected byte[] serializeToByteArray(Object deserializedObject)
                               throws Exception

Description copied from class: AbstractObjectValueSerializer

Specified by:

serializeToByteArray in class AbstractObjectValueSerializer

Parameters:

deserializedObject - the object to serialize

Returns:

the byte array value of the object

Throws:

Exception

deserializeFromByteArray

Exception

canSerializeValue

protected boolean canSerializeValue(Object value)

Description copied from class: AbstractSerializableValueSerializer

return true if this serializer is able to serialize the provided object.

Specified by:

canSerializeValue in class AbstractSerializableValueSerializer<ObjectValue>

Parameters:

value - the object to test (guaranteed to be a non-null value)

Returns:

true if the serializer can handle the object.
