  • Constructor Details

    • FileListQuestion

      protected FileListQuestion(Interview interview, String tag)
      Create a question with a nominated tag.
      Parameters:
      interview - The interview containing this question.
      tag - A unique tag to identify this specific question.
  • Method Details

    • split

      public static File[] split(String s)
      Break apart a string containing a white-space separate list of file names into an array of individual files. If the string is null or empty, an empty array is returned. The preferred separator is a newline character; if there are no newline characters in the string, then (for backward compatibility) space is accepted instead.
      Parameters:
      s - The string to be broken apart
      Returns:
      An array of files determined from the parameter string.
      See Also:
    • join

      public static String join(File... ff)
      Convert a list of filenames to a newline separated string.
      Parameters:
      ff - an array of filenames
      Returns:
      a string containing the filenames separated by newline characters. If there is just one filename, and if it contains space characters in its path, the list is terminated by a newline as well. If the parameter array is null or empty, an empty string is returned.
      See Also:
    • equal

      protected static boolean equal(File[] f1, File... f2)
      Determine if two arrays of filenames are equal.
      Parameters:
      f1 - the first array to be compared
      f2 - the other array to be compared
      Returns:
      true if both arrays are null, or if neither are null and if their contents match, element for element, in order

    • isValueValid

      public boolean isValueValid()
      Simple validation, upgrade if needed. Iterates values, checks against filters, except if interview semantics are set to an pre-50 version, in which case true is always returned. Using semantics greater than 50 is highly recommended and recommended if an old interview is being modernized.
      Specified by:
      isValueValid in class Question
      Returns:
      False if any values are rejected by filters, true otherwise. True if there are no values or no filters.
      See Also:
    • isValueAlwaysValid

      public boolean isValueAlwaysValid()
      Description copied from class: Question
      Check if the question always has a valid response. This may be true, for example, for a choice question with a default response.
      Specified by:
      isValueAlwaysValid in class Question
      Returns:
      true if the question always has a valid response, and false otherwise.
    • getFilters

      public FileFilter[] getFilters()
      Get the filters used to select valid files for a response to this question.
      Returns:
      An array of filters
      See Also:
    • setFilters

      public void setFilters(FileFilter... fs)
      Set the filters used to select valid files for a response to this question. For pre-50 behavior, both the filters and the hint filter values are treated the same, and neither is used for validation (e.g. isValid().
      Parameters:
      fs - An array of filters used to select valid files for a response to this question
      See Also:
    • setFilter

      public void setFilter(FileFilter filter)
      Set a filter used to select valid files for a response to this question.
      Parameters:
      filter - a filter used to select valid files for a response to this question
      See Also:
    • getHintFilters

      public FileFilter[] getHintFilters()
      A set of filters to help users locate the right file/dir. These filters are not used for validating the question value.
      Since:
      5.0
      See Also:
    • setHintFilters

      public void setHintFilters(FileFilter... fs)
      Set the filters which the user can use to help find files among a list of files - this is somewhat exposing of the fact that there is a user interface. This should not be confused with setFilters(), which in version 5.0 or later of the harness, are used to do validity checks on the actual value (e.g.. in isValid().
      Parameters:
      fs - Filters which might be offered to the user.
      Since:
      5.0
