Class DelegatingStatement

java.lang.Object
  extended by org.apache.openjpa.lib.jdbc.DelegatingStatement
All Implemented Interfaces:
Statement, Wrapper, Closeable
Direct Known Subclasses:
JDBCEventConnectionDecorator.EventStatement, JDBCStoreManager.CancelStatement, LoggingConnectionDecorator.LoggingConnection.LoggingStatement

public abstract class DelegatingStatement
extends Object
implements 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.
