All Implemented Interfaces:

java.util.Comparator<FieldSerializer.CachedField>

public class TaggedFieldSerializer<T>
extends FieldSerializer<T>

Serializes objects using direct field assignment for fields that have been tagged. Fields without the TaggedFieldSerializer.Tag annotation are not serialized. New tagged fields can be added without invalidating previously serialized bytes. If any tagged field is removed, previously serialized bytes are invalidated. Instead of removing fields, apply the Deprecated annotation and they will not be serialized. If fields are public, bytecode generation will be used instead of reflection.

Constructor Detail

TaggedFieldSerializer

public TaggedFieldSerializer(Kryo kryo,
                             java.lang.Class type)

Method Detail

initializeCachedFields

protected void initializeCachedFields()

Overrides:

initializeCachedFields in class FieldSerializer<T>

removeField

public void removeField(java.lang.String fieldName)

Description copied from class: FieldSerializer

Removes a field so that it won't be serialized.

Overrides:

removeField in class FieldSerializer<T>

write

public void write(Kryo kryo,
                  Output output,
                  T object)

Description copied from class: Serializer

Writes the bytes for the object to the output.

This method should not be called directly, instead this serializer can be passed to Kryo write methods that accept a serialier.

Overrides:

write in class FieldSerializer<T>

object - May be null if Serializer.getAcceptsNull() is true.

read

public T read(Kryo kryo,
              Input input,
              java.lang.Class<T> type)

Description copied from class: Serializer

Reads bytes and returns a new object of the specified concrete type.

Before Kryo can be used to read child objects, Kryo.reference(Object) must be called with the parent object to ensure it can be referenced by the child objects. Any serializer that uses Kryo to read a child object may need to be reentrant.

This method should not be called directly, instead this serializer can be passed to Kryo read methods that accept a serialier.

Overrides:

read in class FieldSerializer<T>

Returns:

May be null if Serializer.getAcceptsNull() is true.
