1.4

field:UNSPECIFIED_OPTION [NONE]

UNSPECIFIED_OPTION

public static final int UNSPECIFIED_OPTION

OK_CANCEL_OPTION

public static final int OK_CANCEL_OPTION

OK/CANCEL confirmation option.

An underlying security service specifies this as the optionType to a ConfirmationCallback constructor if it requires a confirmation which can be answered with either OK or CANCEL.

See Also:

field:YES [NONE]

YES

public static final int YES

YES option.

If an optionType was specified to this ConfirmationCallback, this option may be specified as a defaultOption or returned as the selected index.

See Also:

field:NO [NONE]

NO

public static final int NO

NO option.

If an optionType was specified to this ConfirmationCallback, this option may be specified as a defaultOption or returned as the selected index.

See Also:

CANCEL option.

If an optionType was specified to this ConfirmationCallback, this option may be specified as a defaultOption or returned as the selected index.

OK option.

If an optionType was specified to this ConfirmationCallback, this option may be specified as a defaultOption or returned as the selected index.

public static final int INFORMATION

INFORMATION message type.

constructor:ConfirmationCallback(int,int,int) [NONE]

ConfirmationCallback

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.

constructor:ConfirmationCallback(int,java.lang.String[],int) [NONE]

ConfirmationCallback

public ConfirmationCallback (int messageType, String[] options, 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. The array is cloned to protect against subsequent modification.; 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.

constructor:ConfirmationCallback(java.lang.String,int,int,int) [NONE]

ConfirmationCallback

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

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.

constructor:ConfirmationCallback(java.lang.String,int,java.lang.String[],int) [NONE]

ConfirmationCallback

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

Construct a ConfirmationCallback with a prompt, message type, a list of options and a default option.

Parameters:: prompt - the prompt used to describe the list of options.; messageType - the message type (INFORMATION, WARNING or ERROR).; options - the list of confirmation options. The array is cloned to protect against subsequent modification.; defaultOption - the default option, represented as an index into the options array.
Throws:: IllegalArgumentException - if prompt is null, if prompt has a length of 0, 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.

method:getPrompt() [NONE]

getPrompt

public String getPrompt()

Get the prompt.

Returns:: the prompt, or null if this ConfirmationCallback was instantiated without a prompt.

method:getMessageType() [NONE]

getMessageType

public int getMessageType()

Get the message type.

Returns:: the message type (INFORMATION, WARNING or ERROR).

method:getOptionType() [NONE]

getOptionType

public int getOptionType()

Get the option type.

If this method returns UNSPECIFIED_OPTION, then this ConfirmationCallback was instantiated with options instead of an optionType. In this case, invoke the getOptions method to determine which confirmation options to display.

Returns:: the option type (YES_NO_OPTION, YES_NO_CANCEL_OPTION or OK_CANCEL_OPTION), or UNSPECIFIED_OPTION if this ConfirmationCallback was instantiated with options instead of an optionType.

method:getOptions() [NONE]

getOptions

public String[] getOptions()

Get the confirmation options.

Returns:: a copy of the list of confirmation options, or null if this ConfirmationCallback was instantiated with an optionType instead of options.

method:getDefaultOption() [NONE]

getDefaultOption

public int getDefaultOption()

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.

method:setSelectedIndex(int) [NONE]

setSelectedIndex

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.

See Also:

method:getSelectedIndex() [NONE]

getSelectedIndex

public int getSelectedIndex()

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. Otherwise, this method returns the selected confirmation option as an index into the options array specified to the constructor of this ConfirmationCallback.
