Class ResultSetIterator.ProtectedResultSetHandler  

java.lang.Object
  safejdbc.ResultSetIterator.ProtectedResultSetHandler

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

Enclosing class:

ResultSetIterator

---

private static class ResultSetIterator.ProtectedResultSetHandler

extends java.lang.Object

implements java.lang.reflect.InvocationHandler

This class uses dynamic proxy functionality to prevent calls to "next" or "close" on a ResultSet. A dynamic proxy was used instead of a "conventional" Decorator pattern because ResultSet has very many methods and this is shorter. It also has better testability.
