Method Detail

• addFrameHandler

   abstract Unit addFrameHandler(FrameHandler frameHandler)

  Registers FrameHandler which will receive preview frames from camera.

  Note, that handlers can intercept frame by returning true from FrameHandler.handleFrame. In such case no other handler will receive callbacks for current frame. Therefore, order in which handlers are added matters.

  All callbacks are invoked from the worker thread, so it is safe to perform "heavy" operations.

  Parameters:

  frameHandler - handler which will receive preview frames.

• removeFrameHandler

   abstract Unit removeFrameHandler(FrameHandler frameHandler)

  Unregisters FrameHandler.

  Parameters:

  frameHandler - handler to unregister.

• getAttachedFrameHandler

   abstract <T extends FrameHandler> T getAttachedFrameHandler(Class<T> clazz)

  Check whether there is same class of FrameHandler attached to the view return object of the same class if exists otherwise null
