Reads the long value from "somewhere". We could get this value from physical hardware, files on disk, etc. For the purpose of this simple example, 42 is returned. This implies every time the value of a BACI long property that uses this class is accessed, 42 will be returned.
Last but definitely not least, it is important to note that this method can be invoked from both ROlong and RWlong properties. - Parameters:
-
| errcode | The error code (as defined in the ACS Error System) that occured while reading this value or 0 if no error occured. It's up to the developer to determine whether an error occured or not. |
| timestamp | The time when the long value was read (presumably from hardware). |
- Returns:
- The value we are looking for.
- Exceptions:
