,ComponentHandler<Integer>
public class DefaultRadioButtonHandler extends AbstractRadioButtonHandler<Integer>
A concrete default implementation of a
CompositeComponentHandler
for a group of radio buttons.An instance of this class is used as
ComponentHandler
for a radio button group if no specific handler class is specified. This implementation just uses the index of the selected button in the group as data. So a Java bean acting as model for a form that contains a radio button group should have a corresponding property of typeInteger
for this group. Note that reallyInteger
should be used instead ofint
because the value can be set to null if no radio button in the group is selected.Implementation note: This class is not thread-safe.

Method Detail
-
getButtonIndex
protected int getButtonIndex(Integer value)
Returns the index of the radio button in the associated group that represents the passed in data value. Because the data value is interpreted as the selected index it is simply returned.- Specified by:
getButtonIndex
in classAbstractRadioButtonHandler<Integer>
- Parameters:
value
- the data value- Returns:
- the index of the corresponding radio button
-
getDataForButton
protected Integer getDataForButton(int idx)
Returns the data value that corresponds to the radio button with the given index. Again because there is a 1:1 mapping between radio button index and data value the index can be directly returned as value.- Specified by:
getDataForButton
in classAbstractRadioButtonHandler<Integer>
- Parameters:
idx
- the index of the selected radio button- Returns:
- the corresponding data value
