Interface ICompletionListener

  • All Known Implementing Classes:
    KeyBindingSupportForAssistant
    public interface ICompletionListener
    A completion listener is informed before the content assistant computes completion proposals.

    In order to provide backward compatibility for clients of ICompletionListener, extension interfaces are used to provide a means of evolution. The following extension interfaces exist:

    • ICompletionListenerExtension since version 3.4 introducing the following functions:
      • additional notification about restarting the current code assist session
    • ICompletionListenerExtension2 since version 3.8 introducing the following functions:
      • additional notification after applying a proposal

    Clients may implement this interface.
