Methods

Modifier and Type	Method and Description
void	registerEntity(java.lang.Object entity) Registers the top level entity before writing it, to allow nested fields to reference their parent entity.
void	registerPriKeyObject(java.lang.Object o) Called via Accessor.writeSecKeyFields for a primary key field with a reference type.
void	writeArrayLength(int length) Called by ObjectArrayFormat and PrimitiveArrayFormat to write the array length.
void	writeEnumConstant(java.lang.String[] names, int index) Called by EnumFormat to write the given index of the enum constant.
void	writeKeyObject(java.lang.Object o, Format fieldFormat) Called for a primary key field or composite key field with a reference type.
void	writeObject(java.lang.Object o, Format fieldFormat) Called via Accessor to write all fields with reference types, except for the primary key field and composite key fields (see writeKeyObject below).
