Interface DatabaseMetaDataCallback

  • 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
    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.

        java.lang.Object processMetaData(java.sql.DatabaseMetaData dbmd)

                                 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:
        java.sql.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)
