public static java.util.Map<java.lang.String,​java.lang.Object> flatProperties​(java.util.Map<java.lang.String,​java.lang.Object> properties)
        Flattens a nested map of properties into a single-level map.

        If the input map is empty or null, the same map instance is returned.

        For example, given the following input: 

        
 {
   "a": "1",
   "b": {
     "c": "2",
     "d": {
       "e": "3"
     }
   }
 }
        The resulting flattened map would be: 
        
 {
   "a": "1",
   "b.c": "2",
   "b.d.e": "3"
 }
        Parameters:
        properties - The map containing potentially nested properties to be flattened.
        Returns:
        A new unmodifiable map with all properties flattened to a single level.
