java.io.Closeable,java.io.DataInput,java.io.ObjectInput,java.io.ObjectStreamConstants,java.lang.AutoCloseable
public final class ReplicationStream extends java.io.ObjectInputStreamCustom subclass ofObjectInputStreamthat loads from the class loader for this web application. This allows classes defined only with the web application to be found correctly.- Author:
