public final class StringHolder extends Object implements Streamable
string
that is mapped into
java String
.
The holders have several application areas. The end user usually
sees them implementing CORBA methods where the primitive type
is passed by reference. While CORBA (or, for example, C) supports
this, the java does not and a wrapper class is required.
