| 14 | This folder contains an example that shows how to implement class variables |
|---|
| 15 | as defined in Smalltalk. The name shared instance variables is however much |
|---|
| 16 | more accurate. In systems like Logtalk, which enables the use of explicit |
|---|
| 17 | metaclasses, true class variables are just the class (as an object) own |
|---|
| 18 | instance variables! |
|---|
| 19 | |
|---|
| 20 | This example defines a root class (root) and three instances (instance1, |
|---|
| 21 | instance2, and instance3). The root class defines a shared instance variable |
|---|
| 22 | (using a dynamic predicate) and the setter and getter methods which implement |
|---|
| 23 | the variable sharing behavior. |
