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.
