## Package org.hibernate.type

A Hibernate `Type` is a strategy for mapping a Java property type to a JDBC type or types.

See:
Description

Interface Summary
AbstractComponentType | Deprecated. in favor of `CompositeType`
AssociationType | A type that represents some kind of association between entities.
BasicType | Marker interface for basic types.
CompositeType | Contract for value types to hold collections and have cascades, etc.
DiscriminatorType<T> | Additional contract for a `Type` may be used for a discriminator.
IdentifierType<T> | Additional contract for a `Type` may be used for a discriminator.
LiteralType<T> | Additional contract for a `Type` that may appear as an SQL literal
PrimitiveType<T> | Additional contract for primitive / primitive wrapper types.
SingleColumnType<T> | Provide convenient methods for binding and extracting values for use with `BasicType`.
StringRepresentableType<T> | Additional, optional contract for types capable of rendering and consuming their values to/from strings.
Type | Defines a mapping between a Java type and one or more JDBC types, as well as describing the in-memory semantics of the given java type (how do we check it for 'dirtiness', how do we copy values, etc).
TypeFactory.TypeScope |
VersionType<T> | Additional contract for types which may be used to version (and optimistic lock) data.
XmlRepresentableType<T> | Additional, optional contract for types whose values can be represented as XML text (either as attribute or element value).
