Remarks

A layer or renderer can provide legend class formatting information via this property, which makes it possible to store legend formatting information with layers in metadata-like fashion. However this is not normally done. Rather, legend formatting information usually comes from the legend.  ILegendItem.LegendClassFormat is used and some patch settings can come from ILegend.LegendFormat .

So, when a legend is created, the code follows this logic:

1. Check if ILegendClass.Format exists for the layer.  If not, use ILegendItem.LegendClassFormat.
2. For the patch settings, if a setting in ILegendItem.LegendClassFormat is null, then use the default value in ILegend.LegendFormat.
