LCP Critical Path Predictor

This directory implements the browser side of the Largest Contentful Paint (LCP) Critical Path Predictor.

  • LCPCriticalPathPredictorDatabase
    • Manages SQLite database and tables.
  • LCPCriticalPathPredictorPersister
    • Implements the service-specific persistent logic using LCPCriticalPathPredictorDatabase as a backend. Currently, there is only one implementation, but we may introduce another implementation that has an in-memory database as a backend if required.
  • LCPCriticalPathPredictorKeyedService
    • A service that predicts LCP Critical Path. Uses LCPCriticalPathPredictorPersister internally.
  • LCPCriticalPathPredictorKeyedServiceFactory
    • A factory to create LCPCriticalPathPredictorKeyedService instances. Instances are created per profile.

Implementation is on-going. See http://crbug.com/1419756 for details.
