org.eclipse.debug.ui
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.

Since:
3.4
