# TPrsStd_Driver Class Reference

Driver for AIS
==============
An abstract class, which - in classes inheriting
from it - allows you to update an
AIS_InteractiveObject or create one if one does
not already exist.
For both creation and update, the interactive
object is filled with information contained in
attributes. These attributes are those found on
the label given as an argument in the method Update.
true is returned if the interactive object was modified by the update.
This class provide an algorithm to Build with its default
values (if Null) or Update (if !Null) an AIS_InteractiveObject
. Resources are found in attributes associated to a given
label.
