Package org.hibernate.mapping

Class Index

java.lang.Object

org.hibernate.mapping.Index

All Implemented Interfaces:

Serializable, Exportable

public class Index
extends Object
implements Exportable, Serializable

A mapping model object representing an index on a relational database table.

We regularize the semantics of unique constraints on nullable columns: two null values are not considered to be "equal" for the purpose of determining uniqueness, just as specified by ANSI SQL and common sense.
