Interface AsyncPage<T>

Type Parameters:

T - the value type that the page holds

All Superinterfaces:

Page<T>

All Known Implementing Classes:

AsyncPageImpl

public interface AsyncPage<T>
extends Page<T>

Interface for asynchronously consuming Google Cloud paginated results.

Use AsyncPage to iterate through all values (also in next pages):

 AsyncPage<T> page = ...; // get an AsyncPage<T> instance
 Iterator<T> iterator = page.iterateAll();
 while (iterator.hasNext()) {
   T value = iterator.next();
   // do something with value
 }

Or handle pagination explicitly:

 AsyncPage<T> page = ...; // get a AsyncPage<T> instance
 while (page != null) {
   for (T value : page.values()) {
     // do something with value
   }
   page = page.nextPageAsync().get();
 }
