Namespace: vigra
VIGRA defines tuple types \p vigra::triple, \p vigra::tuple4, \p vigra::tuple5.
In addition, \p std::pair is imported into namespace vigra from the C++ standard
library. All these types are defined similarly:
<ul>
<li> They are parameterized by the respective number of types. For each tuple,
a constructor is defined that takes that many arguments, e.g.:
\code
template <class First, class Second, class Third>
class Triple { ... };
\endcode
</li>
<li> A number of \p typedef's tells the types stored in the tuple:
\code
typedef ... first_type;
typedef ... second_type;
typedef ... third_type; // triple, tuple4, tuple5 only
typedef ... forth_type; // tuple4, tuple5 only
typedef ... fifth_type; // tuple5 only
\endcode
</li>
<li> Items are stored in the following public attributes:
\code
first;
second;
third; // triple, tuple4, tuple5 only
forth; // tuple4, tuple5 only
fifth; // tuple5 only
\endcode
</li>
</ul>
