Interface IExtensionStateModel

  • public interface IExtensionStateModel
    Allows clients to coordinate state across components that are part of the same logical extension.

    That is, a content provider might vary how it exposes its content based on the state of a specific property in the model. Interested parties may add themselves as IPropertyChangeListeners to track changes in the state model.

    Since:
    3.2
    Restriction:
    This interface is not intended to be implemented by clients.
