+/**
+ *  Array for brushes.
+ *
+ *  This client object can store owned items, but all the real objects
+ *  are on the server side. Also, the order of brushes is maintained on
+ *  the server side.
+ *  
+ * Usage:
+ * @code
+ * 
+ * //Create Visual
+ * CAlfTextVisual* textVisual = control.AppendVisualL( EAlfVisualTypeText, NULL );
+ * 
+ * //Create border brush
+ * CAlfBorderBrush* borderBrush = CAlfBorderBrush::NewL( *iEnv, TAlfXYMetric(TAlfMetric(1)),
+ *             TAlfXYMetric(TAlfMetric(KAlfDefaultBorderBrushEdgeOffsetX, EAlfUnitPixel),
+ *             TAlfMetric(KAlfDefaultBorderBrushEdgeOffsetY, EAlfUnitPixel)));
+ * 
+ * //Enable brush
+ * textVisual->EnableBrushesL();
+ * 
+ * //Get brush array
+ * CAlfBrushArray* brushArray = textVisual->Brushes();
+ * 
+ * //Append border brush in brush array, with ownership transfered
+ * brushArray->AppendL( borderBrush, EAlfHasOwnership );
+ * 
+ * //removes and deletes border brush in brush array
+ * brushArray->Remove(0);
+ * 
+ * //Cleanup
+ * delete iEnv; //Will delete visual , brush array as well.
+ * 
+ * @endcode
