Examples of org.hibernate.id.CompositeNestedGeneratedValueGenerator

org.hibernate.id.CompositeNestedGeneratedValueGenerator
For composite identifiers, defines a number of "nested" generations that need to happen to "fill" the identifier property(s).
This generator is used implicitly for all composite identifier scenarios if an explicit generator is not in place. So it make sense to discuss the various potential scenarios:
- "embedded" composite identifier - this is possible only in HBM mappings as {@code } (notice the lack of both a name and class attributedeclarations). The term {@link org.hibernate.mapping.Component#isEmbedded() "embedded"}here refers to the Hibernate usage which is actually the exact opposite of the JPA meaning of "embedded". Essentially this means that the entity class itself holds the named composite pk properties. This is very similar to the JPA {@code @IdClass}usage, though without a separate pk-class for loading.
- pk-class as entity attribute - this is possible in both annotations ( {@code @EmbeddedId}) and HBM mappings ( {@code })
- "embedded" composite identifier with a pk-class - this is the JPA {@code @IdClass} use caseand is only possible in annotations
Most of the grunt work is done in {@link org.hibernate.mapping.Component}. @author Steve Ebersole
