Method Detail

createPage

protected abstract PageT createPage(PageContext<RequestT,ResponseT,ResourceT> context,
                                    ResponseT response)

createPageAsync

@InternalApi("Visible for testing")
public ApiFuture<PageT> createPageAsync(PageContext<RequestT,ResponseT,ResourceT> context,
                                        ApiFuture<ResponseT> futureResponse)

hasNextPage

public boolean hasNextPage()

Description copied from interface: Page

Returns true if there are more pages that can be retrieved from the API.

Specified by:

hasNextPage in interface Page<RequestT>

getNextPageToken

public String getNextPageToken()

Description copied from interface: Page

Returns the next page token from the response, or an empty string if there are no more pages.

Specified by:

getNextPageToken in interface Page<RequestT>

getNextPage

public PageT getNextPage()

Description copied from interface: Page

Retrieves the next Page object using the next page token, or null if there are no more pages. The hasNextPage() method can be used to check if a Page object is available.

Specified by:

getNextPage in interface Page<RequestT>

getNextPage

public PageT getNextPage(int pageSize)

getNextPageAsync

public ApiFuture<PageT> getNextPageAsync()

Description copied from interface: AsyncPage

Returns a future for the Page object, retrieved using the next page token. If there are no more pages, returns a future which will immediately provide null. The hasNextPage() method can be used to check if a Page object is available.

Specified by:

getNextPageAsync in interface AsyncPage<RequestT>

iterateAll

public Iterable<ResourceT> iterateAll()

Description copied from interface: Page

Returns an iterable that traverses all of the elements of the underlying data source. The data is fetched lazily page by page, where each page may contain multiple elements. A new page is fetched whenever the elements of any particular page are exhausted.

Specified by:

iterateAll in interface Page<RequestT>

getValues

public Iterable<ResourceT> getValues()

Description copied from interface: Page

Returns an iterable over the elements in this page.

Specified by:

getValues in interface Page<RequestT>

getResponse

public ResponseT getResponse()

getRequest

public RequestT getRequest()

getPageElementCount

public int getPageElementCount()
