The special type of question, FinalQuestion, never returns a successor. Within a particular interview, a question may refer to a nested interview, before continuing within the original interview. Any such references to nested interviews are automatically expanded by this method, leaving just the complete set of basic questions on the path.

Returns:
The current active path of questions, based on the requested options. Returns null if no path information is available.

iteratePath

public java.util.Iterator iteratePath(boolean flattenNestedInterviews)
Get an iterator for the set of questions on the current path. The first question is determined by the interview; after that, each question in turn determines its successor. The path ends when a question indicates no successor (or erroneously returns a question that is already on the path, that would otherwise form a cycle). The special type of question, FinalQuestion, never returns a successor. Within a particular interview, a question may refer to a nested interview, before continuing within the original interview. Such nested interviews may optionally be expanded by this method, depending on the arguments.

Parameters:
flattenNestedInterviews - If true, any nested interviews will be expanded in place and returned via the iterator; otherwise, the the nested interview will be returned instead.

public void load(java.util.Map data)
          throws Interview.Fault
Load the state for questions from an archive map. The map will be passed to each question in this interview and in any child interviews, and each question should load its state, according to its tag. The data must normally contain a valid checksum, generated during save(java.util.Map).

Parameters:
data - The archive map from which the state should be loaded.
Throws:
Interview.Fault - if the checksum is found to be incorrect.

load

public void load(java.util.Map data,
                 boolean checkChecksum)
          throws Interview.Fault
Load the state for questions from an archive map. The map will be passed to each question in this interview and in any child interviews, and each question should load its state, according to its tag. The data must normally contain a valid checksum, generated during save(java.util.Map).

Parameters:

Check if the checksum is valid for a set of responses. When responses are saved to a map, they are checksummed, so that they can be checked for validity when reloaded. This method verifies that a set of responses are acceptable for loading.

Parameters:
data - The set of responses to be checked.
okIfOmitted - A boolean determining the response if there is no checksum available in the data
Returns:
true if the responses have a valid checksum, if given, or whether it is OK to monitor the checksum, if not.

save

public void save(java.util.Map data)
Save the state for questions in an archive map. The map will be passed to each question in this interview and in any child interviews, and each question should save its state, according to its tag.

Parameters:
data - The archive in which the values should be saved.

writeLocale

protected static void writeLocale(java.util.Map data)
Writes information about current locale to the given map.
This information is used later to properly restore locale-sensitive values, like numerics.

Parameters:
data - target map to write data to
See Also:
LOCALE, readLocale(Map)

readLocale

protected static java.util.Locale readLocale(java.util.Map data)
Reads information about locale from the given map.
Implementation looks for the string keyed by LOCALE and then tries to decode it to valid locale object.

Parameters:
data - map with interview values
Returns:
locale, decoded from value taken from map; or default (current) locale
See Also:
LOCALE, writeLocale(Map)

export

public void export(java.util.Map data)
Export values for questions on the current path, by calling Question.export(java.util.Map) for each question returned by getPath(). It should be called on the root interview to export the values for all questions on the current path, or it can be called on a sub-interview to export just the values from the question in that sub-interview (and in turn, in any further sub-interviews for which there are questions on the path.) Unchecked exceptions that arise from each question's export method are treated according to the policy set by setExportIgnoreExceptionPolicy for the interview for which export was called. It may be convenient to ignore runtime exceptions during export, if exceptions may be thrown when the interview is incomplete. It may be preferred not to ignore any exceptions, if no exceptions are expected.

Parameters:
data - The map in which the values will be placed.
See Also:
getPath(), setExportIgnoreExceptionPolicy(int), EXPORT_IGNORE_ALL_EXCEPTIONS, EXPORT_IGNORE_RUNTIME_EXCEPTIONS, EXPORT_IGNORE_NO_EXCEPTIONS

getExportIgnoreExceptionPolicy

public int getExportIgnoreExceptionPolicy()
Get a value representing the policy regarding how to treat exceptions that may arise during export.

Returns:
a value representing the policy regarding how to treat exceptions that may arise during export.
See Also:
setExportIgnoreExceptionPolicy(int), export(java.util.Map), EXPORT_IGNORE_ALL_EXCEPTIONS, EXPORT_IGNORE_RUNTIME_EXCEPTIONS, EXPORT_IGNORE_NO_EXCEPTIONS

setExportIgnoreExceptionPolicy

public void setExportIgnoreExceptionPolicy(int policy)
Set the policy regarding how to treat exceptions that may arise during export. The default value is to ignore runtime exceptions.

Parameters:
policy - a value representing the policy regarding how to treat exceptions that may arise during export
See Also:
getExportIgnoreExceptionPolicy(), export(java.util.Map), EXPORT_IGNORE_ALL_EXCEPTIONS, EXPORT_IGNORE_RUNTIME_EXCEPTIONS, EXPORT_IGNORE_NO_EXCEPTIONS

addObserver

public void addObserver(Interview.Observer o)
Add an observer to monitor updates to the interview.

Parameters:
o - an observer to be notified as changes occur

removeObserver

public void removeObserver(Interview.Observer o)
Remove an observer previously registered to monitor updates to the interview.

Parameters:
o - the observer to be removed from the list taht are notified

containsObserver

public boolean containsObserver(Interview.Observer o)

setBaseTag

protected void setBaseTag(java.lang.String newBaseTag)
Change the base tag for this interview. This should not be done for most interviews, since the base tag is the basis for storing loading and storing values, and changing the base tag may lead to unexpected results. Changing the base tag will caused the tags in all statically nested interviews and questions to be updated as well. This method is primarily intended to be used when renaming dynamically allocated loop bodies in ListQuestion.

Parameters:
newBaseTag - the new value for the base tag.

setInterviewSemantics

public void setInterviewSemantics(int value)
This method is being used to toggle changes which are not backwards compatible with existing interviews. Changing this value after you first initialize the top-level interview object is not recommended or supported. This method should be called as soon as possible during construction. It is recommended that you select the most recent version possible when developing a new interview. As this interview ages and the harness libraries progress, the interview should remain locked at the current behavior.

Parameters:
value - Which semantics the interview should use.
Since:
3.2
See Also:
SEMANTIC_PRE_32, SEMANTIC_VERSION_32, SEMANTIC_MAX_VERSION, getInterviewSemantics()

getInterviewSemantics

public int getInterviewSemantics()
Determine which semantics are being used for interview and question behavior. This is important because new behavior in future versions can cause unanticipated code flow, resulting in incorrect behavior of existing code.

Returns:
The semantics that the interview is currently using.
Since:
3.2
See Also:
setInterviewSemantics(int)

getResourceString

protected java.lang.String getResourceString(java.lang.String key,

Get an entry from the resource bundle. If checkAncestorsFirst is true, then the parent and other ancestors bundles will be checked first before this interview's bundle, allowing the root interview a chance to override the default value provided by this interview. Otherwise, the parent bundles will only be checked if this bundle does not provide a value.

Parameters:
key - the name of the entry to be returned
checkAncestorsFirst - whether to recursively call this method on the parent (if any) before checking this bundle, or only afterwards, if this bundle does not provide a value
Returns:
the value of the resource, or null if not found
