<h4>Description</h4>
|
|
|
|
<pre>uses(Object)</pre>
|
|
<p>
|
|
Declares an object that receives messages from predicates defined in the category or object containing the directive. In the current Logtalk version, this is a non-operational directive, which may be used for documentation. Nevertheless, the compiler will warn you of any unknown object referenced using this directive when an entity containing it is compiled. In a forthcoming release, this directive will likely be used to support object namespaces.
