Examples of JoinExpression

com.mysema.query.JoinExpression
JoinExpression is a join element in a {@link Query} instance. @author tiwe
com.netflix.lipstick.model.operators.elements.JoinExpression
Lipstick model object representing a join expression. @author jmagnusson
org.datanucleus.query.expression.JoinExpression
Expression representing a join between a candidate class, and the class of a field of the first class. An example is in JPQL where we have a "from" clause like
```
SELECT ... FROM Product p JOIN p.reviews r
```
so the join between "Product p" and "Review r" using "p.reviews". Can have a JoinExpression to its right.
org.jpox.store.mapped.expression.JoinExpression
An expression representing a JOIN in JPQL terms. @version $Revision: 1.1 $
