Class BooleanHolder

All Implemented Interfaces:
Streamable

public final class BooleanHolder
extends Object
implements Streamable

The Holder for Boolean. For more information on Holder files, see "Generated Files: Holder Files".

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

Since:
JDK1.2
