+ * 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.
