Class None<T>

java.lang.Object

com.atlassian.confluence.cache.option.None<T>

All Implemented Interfaces:

Option<T>, Serializable

Deprecated.

Since 5.6. Use Option.none()

@Deprecated
public class None<T>
extends Object
implements Option<T>

A cached option for no value. This is used when the factory does not find the value to cache and the missing value needs to be cached. The readResolve() method has been implemented to return the singleton instance so the Object.equals(Object) and Object.hashCode() methods behave as expected for objects that have propagated over the distributed cache.
