本页汇总 oaDataAppDef 当前在 oapy 中可用的 Python 接口。

详细说明

template class oaDataAppDef< T > The oaDataAppDef class implements an application-specific extension on a specified class of managed objects in a database。 A data field is added to each object of the specified dataType when the dataType is created。 The default value of the data field is NULL。 When an application is created, it can use the new data field for any necessary purpose。 This type of extension is useful because it allows an application-defined block of data to be associated with each object。 Note: Since the type of data is unknown to OpenAccess, the contents are not byte swapped。 For additional information on defining and using AppDefs, see oaAppDef and Extending the Database in the Programmer's Guide。
