Interface IDebugModelPresentationExtension

  • All Superinterfaces:
    IBaseLabelProvider, IDebugModelPresentation, ILabelProvider, ISourcePresentation

    public interface IDebugModelPresentationExtension
    extends IDebugModelPresentation
    Optional extension for an IDebugModelPresentation. Dynamically controls whether labels are computed in a UI thread. The debug platform calls debug model presentation label related methods that do not implement this interface in a non-UI thread.

    For example, some models may require at least one access in a UI thread to initialize an image registry at which point they may be able to provide labels in a non-UI thread.

    Clients implementing a debug model presentation should also implement this interface to control which thread labels are generated in.
