import java.util.Iterator;

Chain of element made of blobs https://en.wikipedia.org/wiki/Chain. Technically, this is like a list of Elements. This is server side data structure to store binary representation of Cache data. This interface just allows iteration over elements at client side. This structure follows the insertion order, like an ordered list. The Iterator returned by this class allows to traverse the chain starting from first element. /**
