Class JDBCWriterStub

java.lang.Object

java.io.Writer

weblogic.jdbc.common.internal.JDBCWriterStub

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.io.Serializable, java.lang.Appendable, java.lang.AutoCloseable, java.rmi.Remote, JDBCWriter, weblogic.rmi.extensions.server.StubDelegateInfo

public class JDBCWriterStub
extends java.io.Writer
implements JDBCWriter, java.io.Serializable, weblogic.rmi.extensions.server.StubDelegateInfo

This class manages Writer blocks for JDBCCLob chunking. It keeps track of client side Writers and is used by the server side class WriterProxys to read chunks of data from the writer. NOTE: this is the SmartStub info for the server-side JDBC writer stream impl

getStubDelegate

public java.lang.Object getStubDelegate()

Description copied from interface: weblogic.rmi.extensions.server.StubDelegateInfo

Returns the instance of the implementation that corresponds to a stub. This enables a stream to do the reverse mapping of stub to implementation class for any kind of stub (SmartStub or otherwise).
