## net.sourceforge.jtds.jdbcx.proxy
Class StatementProxy

    java.lang.Object
      net.sourceforge.jtds.jdbcx.proxy.StatementProxy

All Implemented Interfaces:
  java.sql.Statement

Direct Known Subclasses:
  PreparedStatementProxy

public class StatementProxy
extends java.lang.Object
implements java.sql.Statement

This class would be better implemented as a java.lang.reflect.Proxy. However, this feature was not added until 1.3 and reflection performance was not improved until 1.4. Since the driver still needs to be compatible with 1.2 and 1.3 this class is used to delegate the calls to a statement with minimal overhead.
