/**
* The Holder for <tt>Double</tt>. For more information on

* "Generated Files: Holder Files"</a>.<P>
* A Holder class for a <code>double</code>
* that is used to store "out" and "inout" parameters in IDL methods.
* If an IDL method signature has an IDL <code>double</code> as an "out"
* or "inout" parameter, the programmer must pass an instance of
* <code>DoubleHolder</code> 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.
* <P>
* If <code>myDoubleHolder</code> is an instance of <code>DoubleHolder</code>,
* the value stored in its <code>value</code> field can be accessed with
* <code>myDoubleHolder.value</code>.
*
* @version 1.14, 09/09/97
