| ClassExpression | | public class ClassExpression extends ScalarExpression (Code) | | An expression representing a class.
This is used as follows :-
- JDOQL : access public static final fields. Here we invoke accessField on the ClassExpression.
- JDOQL : use the "instanceof" operator. Here we invoke instanceOf on an ObjectExpression pass in a ClassExpression
- JPQL : process the FROM candidates so each candidate is a ClassExpression.
Here we set the join(s) for later processing
