Class StringHolder

java.lang.Object

  +--org.omg.CORBA.StringHolder
All Implemented Interfaces:
Streamable
public final class StringHolder
extends Object
implements Streamable

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

Field Summary

          Reads the unmarshalled data from input and assigns it to the value field of this StringHolder object.
 TypeCode _type()
          Retreives the TypeCode object that corresponds to the value held in this StringHolder object.
