DetectionTaskCallback
Stay organized with collections

Interface for defining a post-processing action to be executed for each detection.This is
used by CameraXSource
for the pipeline to feed camera frames to detectors and invoke callbacks that are set by
developers. Developers must override the
onDetectionTaskReceived(Task) callback in order to receive detection tasks.
Public Methods
public abstract void onDetectionTaskReceived (Task<ResultT> detectionTask)
