摘要
The Aixm51ExportInfo object provides access to export settings used by the AIXM 5.1 exporter. This object contains a dictionary of tables and matching queries to export, as well as an export_type property determining the type of AIXM 5.1 message to export.
说明
The object is used by the ExportAixm51 function. Once created, the queries dictionary may be populated using the tables to export as keys and SQL where clauses as values. The type of export message can be accessed and modified via the export_type property.
