  com.zentense.step2.model.ResultSetModel
      com.zentense.step2.model.AutoModel
          com.zentense.step2.model.AutoI18NModel

public class AutoI18NModel
extends AutoModel

An extended AutoModel that supports internationalized columns. When a model has columns that are foreign keys to table 'i18n', then these columns are considered I18N columns, and the model an AutoI18NModel.

prepare

public ResultSetModel prepare(int type,
                              int concur)

Description copied from class: ResultSetModel

Sets the features for the next resultset generated by this model

Overrides:

prepare in class ResultSetModel

Parameters:

type - JDBC Resultset scroll type

concur - JDBC Resultset concurrency

Returns:

The model itself

doQuery

public final View doQuery(java.lang.String query)

Description copied from class: ResultSetModel

Executes a SQL query using JDBC. The query must be a select or other query that generate results. Use doUpdate for inserts, updates, deletes and alter tables. If rowMode was invoked before this method, the returned view is open and ready to be accessed. Otherwise view is positiones before the first row and a call to next or first must be done in order to position the view at the first available row.

Overrides:

doQuery in class ResultSetModel

Parameters:

query - SQL statement to execute

Returns:

An instance of ResultSetView containing the ResultSet

doUpdate

public final void doUpdate(java.lang.String query)

Description copied from class: ResultSetModel

Executes a SQL statement using JDBC. The statement must be a insert, delete, updates, or alter table because this methods does not return results.

Overrides:

doUpdate in class ResultSetModel

Parameters:

query - SQL statement to execute

delete

public final void delete(java.lang.Object id)

Description copied from class: ResultSetModel

Executes a delete query (delete from table where id= ...)

Overrides:

delete in class ResultSetModel

Parameters:

id - Identifier value of row to be deleted

deleteI18N

public final void deleteI18N(View v)

Deletes all i18n texts (all languages) of any I18N column on current row from given view.
