Document Summary

= container for displaying large data sets that can be scrolled very efficiently by maintaining a limited number of recycled views. Best to use with data collections whose elements change at runtime based on user action or network events. Can be assigned in either xml or java. Applies references to the views contained in recyclerview, and is then passed to onbindviewholder to attach data to. Works as a bridge between the xml and java. Reduces the number of findviewbyid() calls we need to make, as they are expensive. In this case, specific data type is any type that extends viewholder. Use of this class eliminates repeated use of findviewbyid for every list item. Saves addresses obtained by findviewbyid in a hash map, then only uses it again when addresses needed aren"t in hash map. Nested inside adapter class, since that is the only place it will be referenced. = a class called adapter nested inside the recyclerview class.
