J2ME in a Nutshell

Name

RecordListener

Synopsis

This interface is implemented by classes that wish to be notified of changes to the content of one or more RecordStores. A listener is registered by calling the addRecordListener() method of a RecordStore and removed using the removeRecordListener() method.

This interface has three methods. The recordAdded() method is called when a new record is added to a RecordStore. recordDeleted() is called when a new record is removed from a RecordStore. Finally, recordChanged() is called when the content of an existing record is modified. Each of these methods are passed a reference to the RecordStore and the ID of the affected record. This allows a single listener to monitor more than one RecordStore. Note that in the case of recordDeleted(), the record ID will already be invalid by the time this method is invoked, so it is not possible to retrieve the contents of the deleted record.

public interface RecordListener {  
// Public Instance Methods
   public abstract void recordAdded(RecordStore recordStore, 
        int recordId);  
   public abstract void recordChanged(RecordStore recordStore, 
        int recordId);  
   public abstract void recordDeleted(RecordStore recordStore, 
        int recordId);  
}
