Class StatementProxy

Implemented Interfaces:
Statement
Known Direct Subclasses:
PreparedStatementProxy
public class StatementProxy
extends java.lang.Object
implements 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.
