Class ClassExpression

  • All Implemented Interfaces:

    public class ClassExpression
    extends Expression
    Expression representing a candidate in a FROM clause. This is used in JPQL where we have a "from" clause like
     SELECT ... FROM Product p JOIN r
    so the ClassExpression is for alias "p" of type Product. The class name is stored in the Symbol, keyed by this alias. Can have a JoinExpression to its right.
