Return to abstract (thing)

In computer terms:

1. An abstract is a [summary] of a [document] or a [file].

2. Not tied to a specific pre-existing example. In [object-oriented programming], a class is declared abstract if there won’t be any [data] or [method]s specific to that class. As an alternative, this is to be used as a [super class] for other classes that will have specific data. Other [class]es can extent the abstract but it cannot be instantiated.
