Method Detail

changesSince

public BaseListOptions changesSince(Date ifModifiedSince)

Only return objects changed since this time.

startAt

public BaseListOptions startAt(long offset)

Indicates where to begin listing. The list will only include objects that occur after the offset. This is convenient for pagination: To get the next page of results use the last result number of the current page + current page offset as the offset.

maxResults

public BaseListOptions maxResults(int limit)

To reduce load on the service, list operations will return a maximum of 1,000 items at a time. To navigate the collection, the parameters limit and offset can be set in the URI (e.g.?limit=0&offset=0). If an offset is given beyond the end of a list an empty list will be returned.

Note that list operations never return itemNotFound (404) faults.
