  org.omg.CORBA.StringHolder

All Implemented Interfaces:

Streamable

public final class StringHolder
extends Object
implements Streamable

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

A Holder class for a String that is used to store "out" and "inout" parameters in IDL operations. If an IDL operation signature has an IDL string as an "out" or "inout" parameter, the programmer must pass an instance of StringHolder 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 myStringHolder is an instance of StringHolder, the value stored in its value field can be accessed with myStringHolder.value.

Since:

JDK1.2
