" cszeZdZdZdeegefdeeddffdd ZdeeBdefd d Z d ed eddfd dZ de fddZ e Z ZS) MultiValuea$Class to hold any multi-valued DICOM value, or any list of items that are all of the same type. This class enforces that any items added to the list are of the correct type, by calling the constructor on any items that are added. Therefore, the constructor must behave nicely if passed an object that is already its type. The constructor should raise :class:`TypeError` if the item cannot be converted. Note, however, that DS and IS types can be a blank string ``''`` rather than an instance of their classes. type_constructorrrNcs||_t|dS)aCreate a new :class:`MultiValue` from an iterable and ensure each item in the :class:`MultiValue` has the same type. Parameters ---------- type_constructor : callable A constructor for the required type for all items. Could be the class, or a factory function. Takes a single parameter and returns the input as the desired type (or raises an appropriate exception). iterable : iterable An iterable (e.g. :class:`list`, :class:`tuple`) of items to initialize the :class:`MultiValue` list. Each item in the iterable is passed to `type_constructor` and the returned value added to the :class:`MultiValue`.
