[top]any
This object is basically a typesafe version of a void*. In particular,
it is a container which can contain only one object but the object may
be of any type.
It is somewhat like the type_safe_union except you don't have to declare
the set of possible content types beforehand. So in some sense this is
like a less typestrict version of the type_safe_union.

objects and other types which represent learned decision functions. It allows you
to write code which contains and processes these decision functions
without needing to know the specific types of decision functions used.

any that is restricted to containing
elements which are some kind of function or function object.

) const
Where
decision_function is a type capable of being stored in an
any_decision_function object.

This is an implementation of a very simple templated container object.
It contains between 0 and 31 objects where each object is listed
explicitly in the tuple's template arguments.
Note that there is only one implementation of this object so there aren't any
different kernels to choose from when you create instances of the tuple object.
So for example, you
could declare a tuple of 3 ints using the following statement:
dlib::tuple<int,int,int> t;
[top]type_safe_union
This object is a type safe analogue of the classic C union object.
The type_safe_union, unlike a union, can contain nonPOD types such
as std::string.
It is also implemented without performing any
heap memory allocations and instead it stores everything on the stack.
C++ Example Programs:
pipe_ex_2.cpp,
bridge_ex.cpp [top]unordered_pair
This object is very similar to the std::pair struct except unordered_pair
is only capable of representing an unordered set of two items rather than
an ordered list of two items like std::pair.
