Examples of org.apache.cayenne.ObjectContext.commitChanges()

org.apache.cayenne.ObjectContext.commitChanges()
Flushes all changes to objects in this context to the parent DataChannel, cascading flush operation all the way through the stack, ultimately saving data in the database.


        ObjectContext context = createDataContext();


        Artist a1 = context.newObject(Artist.class);
        a1.setArtistName("XX");
        context.commitChanges();
        assertFalse(a1.isPostUpdated());


        a1.setArtistName("YY");
        context.commitChanges();
        assertFalse(a1.isPostUpdated());
