All Implemented Interfaces:

public final class DoubleHolder extends Object implements Streamable
The Holder for Double. For more information on Holder files, see "Generated Files: Holder Files".

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.

JDK1.2
