Class VNSequenceRequestHandler

  • All Implemented Interfaces:
    NSObject
    public class VNSequenceRequestHandler
extends NSObject
    Performs requests on a sequence of images. The VNSequenceRequestHandler is created without any specific image source. The -performRequests:on:error: methods will retain the image source for no longer than the lifetime of the call. The VNSequenceRequestHandler can choose to also cache state information related to the previously-processed image sources. API-Since: 11.0
