示例2: IsAtCaretUnitBoundary

        // Wrapper for this.TextView.IsAtCaretUnitBoundary, adds a cache. 
        internal bool IsAtCaretUnitBoundary(TextPointer position)
        { 
            position.DebugAssertGeneration();
            Invariant.Assert(position.HasValidLayout);

            if (_rootNode.CaretUnitBoundaryCacheOffset != position.GetSymbolOffset()) 
            {
                _rootNode.CaretUnitBoundaryCacheOffset = position.GetSymbolOffset(); 
                _rootNode.CaretUnitBoundaryCache = _textview.IsAtCaretUnitBoundary(position); 

                if (!_rootNode.CaretUnitBoundaryCache && position.LogicalDirection == LogicalDirection.Backward) 
                {
                    // In MIL Text and TextView worlds, a position at trailing edge of a newline (with backward gravity)
                    // is not an allowed caret stop.
                    // However, in TextPointer world we must allow such a position to be a valid insertion position, 
                    // since it breaks textrange normalization for empty ranges.
                    // Hence, we need to check for TextView.IsAtCaretUnitBoundary in reverse direction here. 
 
                    TextPointer positionForwardGravity = position.GetPositionAtOffset(0, LogicalDirection.Forward);
                    _rootNode.CaretUnitBoundaryCache = _textview.IsAtCaretUnitBoundary(positionForwardGravity);
