The MIDlet project save-me-diamond-powder deals with new records and enable old record edition through StorageManager.
The numbered arrows are related to the following relevant code fragments:
(1) The collector gains focus to receive a new record. There is no difference from previous sample (hello world)
(2) The collector finishes his job and a StorageManager saves collected data into a RMS record. We can store a new record or update an old one.
(3) The StorageManager is asked about all record numbers from a given schema. Afterwards, the StorageManager is manipulated to retrieve values from specific fields for each identified record. This gives us enough information to build a menu of old records.
(4) The StorageManager is manipulated to load a whole record into our collector. At this point we use the collector to edit a previously stored record.

Hi Bellia !
ReplyDeleteGreat framework and blog, success !!!
I am trying to print out a saved schemas contents. I am having a problem getting the integer value for the gasStationBrand that is saved in the schema. How do I convert the Object to an integer?

ReplyDeleteHi,
ReplyDeleteThe schema is the data collector structure - Actually the collected data is saved by StorageManager into device's RMS system.
In order to get data from a choicegroup field, the 1st thing to do is to locate the related ListModel:
ListModel listModel = (ListModel) getCollector().getMediator()
.getChoiceGroupToListModel().get("field.gasStationBrand");
If you intend to get the gasStationBrand from a collector that's been loaded by StorageManager:
Item _item = getCollector().getMediator()
.getField("field.gasStationBrand ");
ChoiceGroup _choice = (ChoiceGroup) _item;
int index = _choice.getSelectedIndex();
String brandLabel = listModel.getLabels()[index];
int brandValue = listModel.getValue(label);
If you intend to retrieve the saved values directly from StorageManager.retrieveValues(...) method :
Object[] values = StorageManager.retrieveValues(schemaName, recordNumber, fieldsList);
int[] brandsValues = (int[]) values[p];
// where "p" is the gasStationbrands defined position in the requested fields list
String firstBrandLabel = listModel.getLabel(brandsValues[o]);
Where can I find the available mask values for putting things in the schema? the example has text, decimal is there an integer mask?
ReplyDeleteHow do I add the source to my netbeans project? I have downloaded the source files... just do not know now to make it so when I ctrl click on a diamond powder method, it will take me to that section of code, so I can see how things are processing, etc.
