Objects are Classes

Rekall objects themselves are structured like classes in an object-oriented language; for instance, as mentioned above, a form is a special type of block. The complete structure is shown below; hence KBItem, KBButton and KBLabel are special cases of KBObject. Those marked with an asterisk never exist in their own right, but only as part of some more specialised object (in object-oriented terms, they are abstract base classes).

The names are all prefixed by KB for historical reasons.
