A GDatasource object as defined in GDatasource.py is providing the following

functions in its trigger namespace:
 
10
 
 
11
- createResultSet(conditions={}, readOnly=0)    load a new resultset into the
 
12
                                                datasource
 
13
 
 
14
- simpleQuery(maskDict)                         load a new resultset into the
 
15
                                                datasource and return that 
 
16
                                                result as an dictionary object

The following functions are provided in the global trigger namespace too:

- delete()                                      delete the current record
