Examples with ColumnSource org.hibernate.boot.model.source.spi.ColumnSource used on opensource projects

Example 1 with ColumnSource

use of org.hibernate.boot.model.source.spi.ColumnSource in project hibernate-orm by hibernate.

the class RelationalObjectBinder method bindColumnsAndFormulas.

Example 2 with ColumnSource

use of org.hibernate.boot.model.source.spi.ColumnSource in project hibernate-orm by hibernate.
