Method Detail

initDatasource

protected void initDatasource(AbstractXlsDataSource datasource)
                       throws JRException

JRException

close

public void close()

Description copied from interface: JRQueryExecuter

Closes resources kept open during the data source iteration.

This method is called after the report is filled or the dataset is iterated. If a resource is not needed after the data source has been created, it should be released at the end of createDatasource.

cancelQuery

public boolean cancelQuery()
                    throws JRException
