详细说明

template class oaVarDataAppDef< T > The oaVarDataAppDef class implements an application-specific extension to a particular type of data in a database。 When the objects are created, a data field is added to each object of the specified dataType。 Applications can use the new data field for whatever purpose is necessary。 This type of extension is useful because it allows variable-sized data for each object being extended。 This is similar to the oaDataAppDef class, but more general because the data size can differ for each object。 (There is a minor speed and size penalty for this additional flexibility.) The default value for this extension is zero bytes。 Note: Because the type of data is unknown to OpenAccess, it is unmanaged。 This means 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。
