java.lang.Objectorg.omg.CORBA.DoubleHolder
public final class DoubleHolder
A holder for CORBA double
that is mapped into
java double
.
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.
