public final class TypeCodeHolder extends Object implements Streamable
The Holder for TypeCode. For more information on Holder files, see "Generated Files: Holder Files".

A Holder class for a TypeCode object that is used to store "out" and "inout" parameters in IDL operations. If an IDL operation signature has an IDL TypeCode as an "out" or "inout" parameter, the programmer must pass an instance of TypeCodeHolder as the corresponding parameter in the method invocation; for "inout" parameters, the programmer must also fill the "in" value to be sent to the server. Before the method invocation returns, the ORB will fill in the value corresponding to the "out" value returned from the server.

If myTypeCodeHolder is an instance of TypeCodeHolder, the value stored in its value field can be accessed with myTypeCodeHolder.value.

JDK1.2
