LargeFaceList - List Face
List faces' persistedFaceId and userData in a specified large face list.
- Faces are stored in alphabetical order of persistedFaceId created in LargeFaceList Face - Add.
- "start" parameter (string, optional) is a persistedFaceId value that returned entries have larger ids by string comparison. "start" set to empty to indicate return from the first item.
- "top" parameter (int, optional) specifies the number of entries to return. A maximal of 1000 entries can be returned in one call. To fetch more, you can specify "start" with the last returned entry’s persistedFaceId of the current call.
"start=&top=" will return all 5 persons.
"start=&top=2" will return "face1", "face2".
"start=face2&top=3" will return "face3", "face4", "face5".
