Class DelegatingPreparedStatement

java.lang.Object
  extended by org.apache.openjpa.lib.jdbc.DelegatingPreparedStatement
All Implemented Interfaces:
PreparedStatement, Statement, Wrapper, Closeable
Direct Known Subclasses:
JDBCEventConnectionDecorator.EventPreparedStatement, JDBCStoreManager.CancelPreparedStatement, LoggingConnectionDecorator.LoggingConnection.LoggingPreparedStatement, PostgresDictionary.PostgresPreparedStatement

public abstract class DelegatingPreparedStatement
extends Object
implements PreparedStatement, 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.
