public final class DoubleHolder extends Object implements Streamable
A Holder class for a double
that is used to store "out" and "inout" parameters in IDL methods.
If an IDL method signature has an IDL double as an "out"
or "inout" parameter, the programmer must pass an instance of
DoubleHolder 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 myDoubleHolder is an instance of DoubleHolder,
the value stored in its value field can be accessed with
myDoubleHolder.value.
