Package org.hibernate.type.descriptor.jdbc

Defines handling of almost the full range of standard JDBC-defined SQL data types. Each JDBC type is described by an implementation of JdbcType.

See this discussion of the role JdbcType plays in basic type mappings.

We omit certain JDBC types here solely because Hibernate does not use them itself, not due to any inability to provide proper descriptors for them. There are no descriptors for:

• DATALINK
• DISTINCT
• REF
• REF_CURSOR

Nor is there a generic descriptor for STRUCT defined in this package, but dialect-specific implementations are provided elsewhere.

On the other hand, we actually extend the set of JDBC types by enumerating additional types in SqlTypes.
