Constructor Detail

ColumnProcessor

public ColumnProcessor(Class<B> clazz)

Constructor.

Parameters:

clazz - the class of the bean.

Method Detail

getWritingProcessor

public boolean getWritingProcessor(Field field,
                                   Map<Integer,List<CellProcessor<B>>> map)

Complete a map with the cellprocessor built from the column annotation setted on a field.

Parameters:

field - the field (of the beanClass) from which build the cell processor.

map - the map to complete with the CellProcessor built from column annotation setted on the field. the keys are the cell num target of the cellProcessor.

Returns:

true if no error happens during this operation.

getReadingProcessor

public boolean getReadingProcessor(int translate,
                                   Field field,
                                   List<IPropertyProcessor<B>> propertyProcessors,
                                   Map<Integer,Integer> map)

Complete a list with the propertyProcessor built from the column annotation setted on a field.

Parameters:

translate - column index to add to the column num found on the field. Useful to define the index of a field herited by an embedded attribute.

field - the field (of the beanClass) from which read the Column annotation

propertyProcessors - the list to complete

map - the map to complete. this map shows for each cell num the count of the property processors setted on.

Returns:

true if no errors occurs.

chekcAsSubClass

private boolean chekcAsSubClass(Field field,
                                Column column)

check if the concrete class declared on a column is a subclass of a field.

Parameters:

field - the field

column - the column annotation setted on the field

Returns:

true if the concrete class is a subclass of the field.

checkConcreteClass

private boolean checkConcreteClass(Field field,
                                   Class<?> fieldConcreteClass)

Check if a class is concrete.

Parameters:

field - the field on which the processor works.

fieldConcreteClass - concrete class to use to instanciate the field.

Returns:

true if the class is concrete.

getDefaultValue

private String getDefaultValue(Column column)

Return the default value defined on a column annotation.

Parameters:

column - the column

Returns:

the default value as String.
