public class BrowseIterator

Constructor Detail

BrowseIterator

public BrowseIterator(@NonNull
                      Index index,

                      @NonNull
                      BrowseIterator.BrowseIteratorHandler handler)

Construct a new browse iterator. NOTE: The iteration does not start automatically. You have to call start() explicitly.

Parameters:

index - The index to be browsed.

query - The query used to filter the results.

handler - Handler called for each batch of results.

Method Detail

start

public void start()

cancel

public void cancel()

Cancel the iteration. This cancels any currently ongoing request, and cancels the iteration. The listener will not be called after the iteration has been cancelled.

hasNext

public boolean hasNext()

Determine if there is more content to be browsed. WARNING: Can only be called from the handler, once the iteration has started.
