Summary

Adds a context to a list.

Pascal

 procedureDoAddContext(Context: IJvDataContext); virtual; abstract;

Parameters

Parameters	Description
Context: IJvDataContext	Context to add to the list.

Description

DoAddContext adds a context to the list. It is called by the implementer of IJvDataContextsManager.Add and IJvDataContextsManager.New.
DoAddContext should:

• check if the context is already added (and do nothing if it is).
• check if the specified context has a unique name (if it hasn't, an exception should be raised).
• notify the clients a context is about to be added.
• add the context to the list.
• notify the clients the context has been added to the list.
  

Each descendant of TJvBaseDataContexts that implements a list should implement this method as well.
