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.
