Class Overview

Used to pass context information to producers.

Object implementing this interface is passed to all producers participating in pipeline request . Its responsibility is to instruct producers which image should be fetched/decoded/resized/cached etc. This class also handles request cancellation.

In order to be notified when cancellation is requested, a producer should use the runOnCancellationRequested method which takes an instance of Runnable and executes it when the pipeline client cancels the image request.
