Summary

Deletes the specified context.

Pascal

 procedureDoDeleteContext(Index: Integer); virtual; abstract;

Parameters

Parameters	Description
Index: Integer	Index of the context to delete.

Description

DoDeleteContext deletes the context at the specified index. It might be called by the implementer of IJvDataContextsManager.Delete or by DoRemoveContext, depending on the implementation of the specified methods. In addition it can be called by DoClearContexts to delete all contexts.
DoDeleteContext should:

• check if the context is deletable (and do nothing if it isn't).
• notify clients the context is about to be deleted.
• delete the context from the list.
• notify clients the context has been deleted.
  

Note that you can implement DoDeleteContext by retrieving the context and call DoRemoveContext.
