| org.springframework.jdbc.support.DatabaseMetaDataCallback |
Class Overview
A callback interface used by the JdbcUtils class. Implementations of this
interface perform the actual work of extracting database meta data, but
don't need to worry about exception handling. SQLExceptions will be caught
and handled correctly by the JdbcUtils class.
Public Methods
Implementations must implement this method to process the meta data
passed in. Exactly what the implementation chooses to do is up to it.
Parameters
| dbmd
| the DatabaseMetaData to process |
Returns
- a result object extracted from the meta data
(can be an arbitrary object, as needed by the implementation)
Throws
| 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)
