The Holder for ValueBase. For more information on Holder files, see "Generated Files: Holder Files".

A Holder class for a java.io.Serializable that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL ValueBase as an "out" or "inout" parameter, the programmer must pass an instance of ValueBaseHolder 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 myValueBaseHolder is an instance of ValueBaseHolder, the value stored in its value field can be accessed with myValueBaseHolder.value.
