tableRegistry - the registry for DTO-to-table mappings

tableMapper - the mapper for converting DTO definitions to table definitions

changeTracker - the tracker for monitoring DTO changes

lookup - the lookup for accessing DTO fields

Method Details

register

public void register(Class<?> dtoClass,
 Function<RegistrationContext,RegistrationContextTerminal> rc)

Registers a DTO class along with its associated table specification using the provided registration context function.

Parameters:

dtoClass - The class object of the DTO (Data Transfer Object) to be registered.

rc - A function that takes a RegistrationContext instance to configure the table mapping.

register

public void register(Class<?>... entityClasses)

Registers annotated entity class(es).

The annotated entity must be annotated with Table and contain at least one field annotated with Column, OneToMany or ManyToMany.

Parameters:

entityClasses - the class(es) of the entity/entities to be registered.

register

public void register(DtoTableSpec... dtoTableSpecs)

Register a Data Transfer Object (DTO) class(es) with its corresponding table specification(s).

This method maps the DTO class to a database table and stores the association in the table registry to enable database operations such as insert, update, or query.

Parameters:

dtoTableSpecs - One or more DTO-to-table mapping details
