We want to define a set of predicates to handle dynamic object attributes. We need public predicates to set, get, and delete attributes, and a private dynamic predicate to store the attributes values. Let us name these predicates <code>set_attribute/2</code> and <code>get_attribute/2</code>, for getting and setting an attribute value, <code>del_attribute/2</code> and <code>del_attributes/2</code>, for deleting attributes, and <code>attribute_/2</code>, for storing the attributes values.

We do not want to encapsulate these predicates in an object. Why? Because they are a set of usefull, closely related, predicates that may be used by several, unrelated, objects. If defined at an object level, we would be constrained to use inheritance in order to have the predicates available to other objects. Furthermore, this could force us to use multi-inheritance or to have some kind of generic root object containing all kinds of possible useful predicates.

For this kind of situation, Logtalk enables the programmer to encapsulate the predicates in a <em>category</em>, so that they can be used in any object. A category is a Logtalk entity, at the same level as objects and protocols. It can contain predicates directives and/or definitions. Category predicates can be imported by any object, without code duplication and without resorting to inheritance.

Logtalk objects should be regarded as a way to encapsulate and reuse predicate definitions. Instead of a single clause database containing all your code, Logtalk objects provide separated namespaces or databases allowing the partitioning of code in more manageable parts. Logtalk does not try to bring some sort of new dynamic state change concept to Logic Programming or Prolog. Logtalk objects should be regarded as a way to encapsulate and reuse predicate definitions.

In Logtalk, the only pre-defined objects are the pseudo-objects <code>user</code> and <code>debugger</code>, which are described later at the end of this section.
