Implementation Quick Response Code in Java Understanding object/relational persistence

You start by creating a low-pass filter B and then taking the inverse of it C in order to get relatively clean movement data. Because the data can be a little dirty at the start, you don t accept any acceleration data sent in the first second D. You could cut this down to a mere fraction of a second. You start looking for movement whenever one of the accelerometers goes above .3 g. When that occurs, you save the direction of highest movement E and keep measuring it until movement drops below .3 g. Afterward, you make sure that at least a tenth of a second has passed, so that you know you re not in a lull during a movement. Finally, you do whatever you want to do with your movement data. This example reports the information in a label, but you d doubtless do something much more intricate in a live program. Cleanup is required to get the next iteration of movement reporting going. This sample program works well, unless the movement is very subtle. In those cases, it occasionally reports the opposite direction because of the force when the device stops its motion. If this type of subtlety is a problem for your application, more work is required. To resolve this, you need to make a better comparison of the start and stop forces for movements; if they re similar in magnitude, you ll usually want to use the first force measured, not necessarily the biggest one. But for the majority of cases, the code in listing 10.1 is sufficient. You now have an application that can accurately report (and take action based on) direction of movement.

The loadPage() function is the code ultimately responsible for responding to each request to fetch a fresh page of thumbnails from the web service. The entire function is based on a strange new type of operation called a transition. We ve yet to see a transition in any of the projects so far, so let s stop and examine it in detail.

If you map two parallel collections (their owning entity is the same) with an eager outer-join fetching strategy, and load all Item objects, Hibernate executes an SQL SELECT that creates a product of the two collections:

database creation @Override public void onCreate(SQLiteDatabase db) { try { Override db.execSQL(DBOpenHelper.DB_CREATE); helper callbacks } catch (SQLException e) { Log.e("ProviderWidgets", DBHelper.CLASSNAME, e); } }

How about that! Except for the first declaration line, the content is identical to the final XML. The new XML Literals feature makes building XML documents a snap. The content gets stored in the new XDocument object, part of the System.Xml.Linq namespace. If you want to store just a section of XML instead of the entire document, use the XElement class instead.
