control point
In the narrowest terms, control points refer to the eight
point types found in the baja control palette under
the Points folder. In broader terms, control
points include components from the control and kitControl palettes. Most of these components are based
on the eight basic point types. They inherit from BooleanPoint, EnumPoint,
NumericPoint, and StringPoint.
ControlPoint is the base class for all point types in the Baja control architecture. A ControlPoint maps to one value that a driver reads or writes. All ControlPoints have a StatusValue property called Out.
If the predefined proxyExt is not a NullProxyEct, the system considers the point a proxy point. This means that it is a local representation of a point that actually exists in an external device. The framework uses the driver to maintain synchronization.
