As it becomes slower and slower to find last changes I think I need an index.
The 2 classes are just simplified reality.
HowTo ?

Class Rick.ChangeItem Extends %SerialObject

Property Subject As %String;

Property Author As %String;

Property Change As %TimeStamp;
}

ClassMethods with a private keyword tags

My questions are regarding ClassMethods with a private keyword tags.

When we use a wizard to add a new method, we are given a options to
select private checkbox to make it a private method as well as
Class Method checkbox in the same time.

1. What would be the reason and the case to select and use them both?
2. Secondly, if there is such a case in already developed application is it
safe to remove the private tag from ClassMethod? Obviously if it's not a
ClassMethod private tag cannot be removed as easily.

Thank you,
