@JavaServiceLoadable
public interface TypeContributor

An object that contributes custom types and type descriptors, eventually to a TypeConfiguration, via an instance of TypeContributions.

• The most common way to integrate a TypeContributor is by making it discoverable via the Java ServiceLoader facility.
• Alternatively, a TypeContributor may be programmatically supplied to Configuration.registerTypeContributor(TypeContributor) or even MetadataBuilder.applyTypes(TypeContributor).
• When bootstrapping Hibernate via JPA or Configuration, Finally, in the JPA boostrap process, TypeContributors may be listed via JpaSettings.TYPE_CONTRIBUTORS.

Method Summary

Modifier and Type	Method	Description
void	contribute(TypeContributions typeContributions, ServiceRegistry serviceRegistry)	Contribute types
default int	ordinal()	Determines order in which the contributions will be applied (lowest ordinal first).

Method Details

contribute

void contribute(TypeContributions typeContributions,
 ServiceRegistry serviceRegistry)

Contribute types

Parameters:

typeContributions - The callback for adding contributed types

serviceRegistry - The service registry

ordinal

default int ordinal()

Determines order in which the contributions will be applied (lowest ordinal first).

The range 0-500 is reserved for Hibernate, range 500-1000 for libraries and 1000-Integer.MAX_VALUE for user-defined TypeContributors.

Contributions from higher precedence contributors (higher numbers) effectively override contributions from lower precedence. E.g. if a contributor with precedence 2000 contributes some type, that will override Hibernate's standard type of that name.

Returns:

the ordinal for this TypeContributor
