Summary

Clears the context list.

Pascal

 procedureDoClearContexts; virtual; abstract;

Description

DoClearContexts clears the list of contexts. It is called by the implementer of IJvDataContextsManager.Clear.
DoClearContexts should only delete deletable contexts, which implies that after a call to DoClearContexts the list isn't necessarily empty. For each context that is removed, the client needs to be notified (both before the deletion as well as after).
The best way to implement this is to iterate the list from the last to the first context and call DoDeleteContext for each of them.
