DelegatingStatement

java.lang.Object
- org.apache.openjpa.lib.jdbc.DelegatingStatement

All Implemented Interfaces:

java.sql.Statement, java.sql.Wrapper, Closeable

Direct Known Subclasses:

JDBCEventConnectionDecorator.EventStatement, JDBCStoreManager.CancelStatement, LoggingConnectionDecorator.LoggingConnection.LoggingStatement
```
public abstract class DelegatingStatement
extends java.lang.Object
implements java.sql.Statement, Closeable
```
Wrapper around an existing statement. Subclasses can override the methods whose behavior they mean to change. The equals and hashCode methods pass through to the base underlying data store statement.
