Class EagerPaginator<Resp,​T>

  • All Implemented Interfaces:
    java.util.Iterator<T>
    Direct Known Subclasses:
    ListScheduleListDescriptionIterator
    public abstract class EagerPaginator<Resp,​T>
extends java.lang.Object
implements java.util.Iterator<T>
    The main goal for this Iterator implementation is to abstract the functionality of "eager pagination". This implementation requests the next page when we start iterating through the previous page. The main goal of this approach is to reduce a synchronous wait that would otherwise happen when a first element of the next page is requested.
