public ConfirmationCallback(int messageType,
                    int optionType,
                    int defaultOption)
```
    Construct a ConfirmationCallback with a message type, an option type and a default option.
    Underlying security services use this constructor if they require either a YES/NO, YES/NO/CANCEL or OK/CANCEL confirmation.
    
    Parameters:
    messageType - the message type (INFORMATION, WARNING or ERROR).
    optionType - the option type (YES_NO_OPTION, YES_NO_CANCEL_OPTION or OK_CANCEL_OPTION).
    defaultOption - the default option from the provided optionType (YES, NO, CANCEL or OK).
    
    Throws:
    
    IllegalArgumentException - if messageType is not either INFORMATION, WARNING, or ERROR, if optionType is not either YES_NO_OPTION, YES_NO_CANCEL_OPTION, or OK_CANCEL_OPTION, or if defaultOption does not correspond to one of the options in optionType.

                    int defaultOption)
```
    Construct a ConfirmationCallback with a message type, a list of options and a default option.
    Underlying security services use this constructor if they require a confirmation different from the available preset confirmations provided (for example, CONTINUE/ABORT or STOP/GO). The confirmation options are listed in the options array, and are displayed by the CallbackHandler implementation in a manner consistent with the way preset options are displayed.
    
    Parameters:
    messageType - the message type (INFORMATION, WARNING or ERROR).
    options - the list of confirmation options.
    defaultOption - the default option, represented as an index into the options array.
    
    Throws:
    
    IllegalArgumentException - if messageType is not either INFORMATION, WARNING, or ERROR, if options is null, if options has a length of 0, if any element from options is null, if any element from options has a length of 0, or if defaultOption does not lie within the array boundaries of options.

    Get the default option.
    
    Returns:
    the default option, represented as YES, NO, OK or CANCEL if an optionType was specified to the constructor of this ConfirmationCallback. Otherwise, this method returns the default option as an index into the options array specified to the constructor of this ConfirmationCallback.

public void setSelectedIndex(int selection)
```
    Set the selected confirmation option.
    
    Parameters:
    selection - the selection represented as YES, NO, OK or CANCEL if an optionType was specified to the constructor of this ConfirmationCallback. Otherwise, the selection represents the index into the options array specified to the constructor of this ConfirmationCallback.

    Get the selected confirmation option.
    
    Returns:
    the selected confirmation option represented as YES, NO, OK or CANCEL if an optionType was specified to the constructor of this ConfirmationCallback.
