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.

    • Method Detail

      • processMetaData

        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)
