public interface Streamable

The base class for the Holder classess of all complex IDL types. The ORB treats all generated Holders as Streamable to invoke the methods for marshalling and unmarshalling.

Since:: JDK1.2

Method Summary

void _read(InputStream istream)
          Reads data from istream and initalizes the value field of the Holder with the unmarshalled data.

TypeCode _type()
          Retrieves the TypeCode object corresponding to the value in the value field of the Holder.

void _write(OutputStream ostream)
          Marshals to ostream the value in the value field of the Holder.
