Class StatementWrapper

java.lang.Object
  |
  +--com.solarmetric.datasource.StatementWrapper

All Implemented Interfaces:

Statement

Direct Known Subclasses:

PreparedStatementWrapper

public class StatementWrapper

extends Object

implements Statement

Wrapper around an existing Statement. Subclasses can override those methods whose behavior they want to change.

This class also enforces that the owned ResultSet has been closed before executing a new Query. This is not in violation of the JDBC specification, merely a more strict enforement of a best practice.
