Examples of org.apache.cayenne.exp.Expression.transform()

org.apache.cayenne.exp.Expression.transform()
Creates a transformed copy of this expression, applying transformation provided by Transformer to all its nodes. Null transformer will result in an identical deep copy of this expression.
To force a node and its children to be pruned from the copy, Transformer should return Expression.PRUNED_NODE. Otherwise an expectation is that if a node is an Expression it must be transformed to null or another Expression. Any other object type would result in a ExpressionException. @since 1.1
