| [birt-dev]CheckIn: new api of DataExtractionTask |
Description:
Why: The previous data export feature only deal with one table/list/chart instance and depend the user to select on item, which is deemed as inconvenient.
Fix: The new IDataExtractionTask provide multiple result set from which user can select one and the corresponding columns to export data. The new calling sequence is:
1. IDataExtractionTask.getResultSetList( ) which will return a list of IResultSetItem.
IResultSetItem.getResultSetName( ) to return the result set display name
IResultSetItem.getResultMetaData( ) to return the meta data of the result set, note here the meta data only contains column name and column count.
2. IDataExtractionTask.selectResultSet( ) to select from which resultset to export data.
3. IDataExtractionTask.selectColumns( )
4. IDataExtractionTask.extract( )
