com.sigmadynamics.sdo.support
Class SDApplicationBase

java.lang.Object
com.sigmadynamics.sdo.support.SDOBase
com.sigmadynamics.sdo.support.SDApplicationBase

All Implemented Interfaces:

ApplicationInterface, SDOInterface

Direct Known Subclasses:

ApplicationBase

public abstract class SDApplicationBase

extends SDOBase

implements ApplicationInterface

Abstract base class for the Application class in generated code, the most important class of an Inline Service. An Inline Service's lifecycle is managed through this class. The Application (bottommost subclass of SDApplicationBase) serves as the main gateway between the RTD Decision Server and an Inline Service.

rebuildPredictionModels

public void rebuildPredictionModels()

Description copied from interface: ApplicationInterface

Rebuilds prediction models for all studies, so they include all recent learnings.

This method asks the Learning Service to do the following sequence of activities, and returns after the sequence has finished.

1. Process all previously unprocessed learning records, by reading them from the database and updating the in-memory learning models to reflect the knowledge encapsulated by the learning records.
2. Persist the newly updated learning models to the database, for all studies.
3. Rebuild all prediction models for all studies.
4. Persist the new prediction models to the database.
5. Wait for the new prediction models to be loaded into memory, where they will be available for making predictions.

Specified by:

rebuildPredictionModels in interface ApplicationInterface
