Interface RenderingContextView

public interface RenderingContextView

View providing an access to the ViewRenderingContext in the view hierarchy.

Accessing of the ViewRenderingContext from a view must always be done like this:


      RenderingContextView rcView = RenderingContextView.get(view);
      if (rcView != null) {
          rcView.acquireRenderingContext();
          try {
              ...
          } finally {
              rcView.releaseRenderingContext();
          }
      }

Only one thread at the time can safely access methods of the RenderingContextView. It does not have to be event dispatch thread.
