Asynchronous Processes

Progress Modes

The following constants represent possible progress modes for an asynchronous process. You call the accessor methods of a progress broadcaster to get and set the progress mode of an asynchronous process.

kMeteredProgress

Progress toward completion can be quantified. For example, if you know in advance the number of bytes to be downloaded, you can meter the progress of a download operation.

kUnmeteredProgress

Progress toward completion cannot be quantified. For example, if you do not know in advance the number of bytes to be downloaded, you cannot meter the progress of a download operation.
