### Configuration Methods and Public Variable Initialization

For efficiency reasons, the configuration methods are not called during the intialization of the public variables. If you want to force the configuration method to be called for a particular public variable, you can specify it in the `-forcecall` section of the class declaration. In the following example, we force the configuration method of the `-direction` variable to be called during intialization:

> `-forcecall {
> -direction
> }`
