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

A Holder class for Any objects that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL any as an "out" or "inout" parameter, the programmer must pass an instance of AnyHolder 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 myAnyHolder is an instance of AnyHolder, the value stored in its value field can be accessed with myAnyHolder.value.

JDK1.2
