Examples of org.hibernate.hql.internal.ast.tree.FromElement

org.hibernate.hql.internal.ast.tree.FromElement
Represents a single mapped class mentioned in an HQL FROM clause. Each class reference will have the following symbols:
- A class name - This is the name of the Java class that is mapped by Hibernate.
- [optional] an HQL alias for the mapped class.
- A table name - The name of the table that is mapped to the Java class.
- A table alias - The alias for the table that will be used in the resulting SQL.
