1.118 NullValueHolder

Defined in namespace Smalltalk

Superclass: ValueAdaptor

Category: Language-Data types

I pretend to store my value in a variable, but I don't actually. You can use the only instance of my class (returned by `ValueHolder null') if you're not interested in a value that is returned as described in ValueHolder's comment.
