    00052     VIGRA defines tuple types \p vigra::triple, \p vigra::tuple4, \p vigra::tuple5.
    00053     In addition, \p std::pair is imported into namespace vigra from the C++ standard
    00054     library. All these types are defined similarly:
    00055
    00056     <ul>
    00057
    00058     <li> They are parameterized by the respective number of types. For each tuple,
    00059     a constructor is defined that takes that many arguments, e.g.:
    00060     \code
    00061     template <class First, class Second, class Third>
    00062     class Triple { ... };
    00063     \endcode
    00064     </li>
    00065     <li> A number of \p typedef's tells the types stored in the tuple:
    00066
    00067     \code
    00068     typedef ... first_type;
    00069     typedef ... second_type;
    00070     typedef ... third_type;  // triple, tuple4, tuple5 only
    00071     typedef ... forth_type;  // tuple4, tuple5 only
    00072     typedef ... fifth_type;  // tuple5 only
    00073     \endcode
    00074     </li>
    00075     <li> Items are stored in the following public attributes:
    00076
    00077     \code
    00078
    00079     first;
    00080     second;
    00081     third;  // triple, tuple4, tuple5 only
    00082     forth;  // tuple4, tuple5 only
    00083     fifth;  // tuple5 only
    00084
    00085     \endcode
    00086     </li>
    00087     </ul>
