public ElsaMaker()

Method Detail

singletons

public ElsaMaker singletons(Object... singletons)

Register list of singletons. Singletons are serialized using only two bytes. Deserialized singletons keep reference equality. Note: Order in which singletons are registered defines storage format. To deserialize data back, you need to always register singleton at the same order.

Parameters:

singletons -

Returns:

this maker

make

public ElsaSerializerPojo make()

Creates new serializer with configuration from this builder

Returns:

new serializer

registerClasses

public ElsaMaker registerClasses(Class... classes)

Register classes structure. It saves space since class structure does not have to be saved together with data. Note: Order in which classes are registered defines storage format. To deserialize data back, you need to always register classes at the same order.

Parameters:

classes -

Returns:

unknownClassNotification

public ElsaMaker unknownClassNotification(ElsaClassCallback callback)

Callback notified when class with unknown structure is serialized.

Parameters:

callback -

Returns:

registerSer

public <E> ElsaMaker registerSer(int header,
                                 Class<E> clazz,
                                 ElsaSerializerBase.Ser<E> ser)

registerDeser

public ElsaMaker registerDeser(int header,
                               ElsaSerializerBase.Deser deser)

referenceDisable
