Object types                                      

The Primary objects                              
Primary objects present the cluster of basic objects OOF. Their main characteristics is to have a pricesily defined number of conditions. We have already shown the construction of primary objects with all those actions which could be performed at one object. The illustration below presents all primary objects.

But, such given objects are useless since they are not doing anything in this moment. In order to make the object do their own job, we have to change some of the qualities and methods. Some of them are common for all the objects. We shall observe any of the filtering objects.
In order to make one object alive, we have to make the emphasis for what particular field in the table, the filter  is to be formed. The name of the quality is “xFilterKey”. The field MUST be introduced with the alias table.

 The other quality is the object name (‘Name’), in order to have it recognized in a number of other given objects.
This is what makes the object alive and when it is switched on, it returns the filter string value – method “xWriteFilter”.
