An easy way to clean ADF BC entity cache

An easy way to clean ADF BC entity cache

It's time to get back to posting. In this short post, the first one after a long break,  I am going to show an easy way to clean up entity cache of a specific entity definition and to force dependent view objects to get re-executed.

Let's say there is a dashboard page containing lots of various charts, diagrams, lists and tables. All that fancy stuff is based on a number of view objects. Let's assume these view objects represent data in different ways from a database table containing some billing information BillingLog. So, there is an entity BillingLogEO and all dashboard VOs are based on this entity. When it comes to dashboards, a common use-case is to get the dashboard refreshed either manually or automatically. We could implement that just by running over all dashboard view objects and re-executing them one-by-one explicitly, or we can just tell the framework to clean up entity cache of BillingLogEO in our application module implementation class:

1	getDBTransaction().clearEntityCache("model.entities.BillingLogEO");

This will clean the specified entity cache in the current transaction and clean VO caches of all dependent view objects which will force them to get re-executed.

That's it!
