Constructor Detail

ConfirmationCallback

public ConfirmationCallback(int messageType,
                            int optionType,
                            int defaultOption)

Class is disabled.

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.

ConfirmationCallback

public ConfirmationCallback(int messageType,
                            String[] options,
                            int defaultOption)

Class is disabled.

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.

ConfirmationCallback

public ConfirmationCallback(String prompt,
                            int messageType,
                            int optionType,
                            int defaultOption)

Class is disabled.

Construct a ConfirmationCallback with a prompt, 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:

prompt - the prompt used to describe the list of options.

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 prompt is null, if prompt has a length of 0, 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.
