public abstract class ColumnHelper
extends java.lang.Object
```
The ASAM ODS column interface. It is not inherited from InstanceElement. Via the method getColumn of the interface SubMatrix the column is accessed. The column is only used for read access. With the creation of instances at the application element of type AoLocalColumn and the relation to the instances of the application element of type AoSubMatrix a local column can be created. The column name is used for the SMatLink and the column is used to store a formula for the calculation of the values of the column. There is no definition of the formula language at the moment.
