Class EagerPaginator<Resp,T>

java.lang.Object

io.temporal.internal.client.EagerPaginator<Resp,T>

All Implemented Interfaces:

Iterator<T>

Direct Known Subclasses:

ListScheduleListDescriptionIterator

public abstract class EagerPaginator<Resp,T>
extends Object
implements 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.
