Object processMetaData(DatabaseMetaData dbmd) throws SQLException, MetaDataAccessException
Implementations must implement this method to process the meta-data passed in. Exactly what the implementation chooses to do is up to it.- 参数:
dbmd- the DatabaseMetaData to process- 返回:
- a result object extracted from the meta-data (can be an arbitrary object, as needed by the implementation)
- 抛出:
SQLException- if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)MetaDataAccessException- in case of other failures while extracting meta-data (for example, reflection failure)
