interface ProcessorInterface in Drupal 8

Defines an interface for aggregator processor implementations.

A processor acts on parsed feed data. Active processors are called at the third and last of the aggregation stages: first, data is downloaded by the active fetcher; second, it is converted to a common format by the active parser; and finally, it is passed to all active processors that manipulate or store the data.
