class TaskJuggler::TextParser

  # This class models the elements of the stack that the TextParser uses to keep
  # track of its state. It stores the current TextParserRule, the current
  # pattern position and the TextScanner position at the start of processing. It
  # also store the function that must be called to store the collected values.

    # the creation of this element. _function_ is the function that will be
    # called at the end to store the collected data. _sourceFileInfo_ is a
    # SourceFileInfo reference that describes the TextScanner position when the
    # rule was entered.
