Constructor Detail

BeanMapper

public BeanMapper(Database<Connection> db,
                  MappingInfo mi,
                  IDFactory idFactory,
                  Class<T> type,
                  Object... topics)
           throws DatabaseException

Throws:

DatabaseException

BeanMapper

public BeanMapper(Database<Connection> db,
                  String tableName,
                  String idColumn,
                  String displayColumn,
                  IDFactory idFactory,
                  Class<T> type,
                  String query)
           throws DatabaseException

Throws:

DatabaseException

Method Detail

addBeanProperty

public void addBeanProperty(String column,
                            Method setterMethod)

addBeanProperty

public void addBeanProperty(String column,
                            String propertyName)

allows to add a column mapping by specifying the property name as a String. Note that polymorphism provides problems in this context! In this case, avoid using this method but use the more explicit addBeanProperty(String, Method).

addBeanProperty(String, Method)

instantiate

public T instantiate(RowItem row)
                              throws Exception

Description copied from interface: ObjectRowMapper

instantiates the DBEntry based on the properties in the given row. The given row contains all the columns of the queried ResultSet unless the columns to be retrieved are restricted by ObjectRowMapper.getRestrictMappedColumns().

Throws:

Exception

mapBeans

protected T mapBeans(RowItem row,
                     T entry)
                              throws Exception

Throws:

Exception

generateRowProperties

protected Map<String,Object> generateRowProperties(T entry)
                                            throws WrongDataException

Description copied from class: BaseRowMapper

generates a map that contains all columns mapped to their values, so that the map can be used to store the object into a row. The ID column and the corresponding ID should not be put in there, as this will happen automatically later.

Specified by:

generateRowProperties in class BaseRowMapper<T extends DBEntry>

Throws:

WrongDataException

mapBeans

protected HashMap<String,Object> mapBeans(T entry,
                                          HashMap<String,Object> map)
                                   throws WrongDataException

Throws:

WrongDataException
