Constructor Details

ChoiceQuestion

protected ChoiceQuestion(Interview interview,
 String tag)

Create a question with a nominated tag. If this constructor is used, the choices must be supplied separately.

Parameters:

interview - The interview containing this question.

tag - A unique tag to identify this specific question.

ChoiceQuestion

protected ChoiceQuestion(Interview interview,
 String tag,
 String... choices)

Create a question with a nominated tag.

Parameters:

interview - The interview containing this question.

tag - A unique tag to identify this specific question.

choices - The set of legal values for responses to this question.

Method Details

setChoices

protected void setChoices(String[] choices,
 boolean localize)

Set the set of legal responses for this question. If the current value is one of the choices (string equality), it will be set identically equal to that choice; otherwise, the current value will be set to the first choice.

Parameters:

choices - An array of strings identifying the set of legal responses for this question. Depending on the value of the 'localize' argument, the strings will be used literally, or will be used to construct keys to look up resources in the containing interview's resource bundle, in order to get the display strings. In both cases, the current value will always be one of the values in the choices array.

localize - if false, the choices will be used directly as the display choices; otherwise the choices will be used to construct keys to get localized values from the interview's resource bundle.

Throws:

NullPointerException - if choices is null.

See Also:

• getChoices()
• setChoices(String[])
• setChoices(String[], String[])

setChoices

protected void setChoices(String[] choices,
 String... displayChoices)

Set the set of legal responses for this question. If the current value is one of the choices (string equality), it will be set identically equal to that choice; otherwise, the current value will be set to the first choice.

Parameters:

choices - An array of strings identifying the set of legal responses for this question.

displayChoices - An array of strings to be presented to the user that identify the legal responses to this question. The value can also be null, to indicate that the display choices should be determined automatically by obtaining localized values for the entries in the choices array.

Throws:

NullPointerException - if choices is null.

IllegalArgumentException - if displayChoices is not null and is a different length than choices.

• getChoices()
• setChoices(String[])
• setChoices(String[], boolean)

setI18NChoices

@Deprecated
protected void setI18NChoices(String... choices)

Deprecated.

Use the other setChoices() methods, which support i18n as an option.

Set the set of legal responses for this question, using the standard resource bundle for localization.

Parameters:

choices - The set of possible responses for this question. Each entry in the argument array is localized by looking up question-key.choices[i] in the standard resource bundle used by the parent interview. If an appropriate entry is not found, the array value (choices[i]) is used instead.
