Interface DatabaseMetaDataCallback<T>

Type Parameters:
T - the result type
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface DatabaseMetaDataCallback<T>
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.

      T 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.
      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 an 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)
