   <title>Containers</title>

   <!-- ************************************************************************* -->

   <body>
         <br/><br/>
         <p>
         Many of these containers were inspired by the RESOLVE/C++ course sequence at Ohio State.  As such, 
         many of the objects do not support copying in any form, only swapping is allowed. That is, when objects 
         are added or removed from most of these containers they are swapped in and out, not copied. 
         </p>

         <p>
         This allows you to do things like have containers of containers of containers without encountering the 
         overhead of the massive copying that would likely result if you did the same thing with the STL. 
         It also means you can store objects that are not copyable inside these containers, which is not 
         something you can do with the STL.  
         </p>

         <p>
         Note that it is assumed by these containers that swap() and operator&lt; do not throw.  They
         may not function correctly if this assumption is broken.  Also note that the built in types (int, long,
         char, etc.) and std::string will not cause operator&lt; or swap() to throw.
         </p>

         <p>
            Note also that most of the containers inherit from the <a href="#enumerable">enumerable</a>
            interface.  Thus, all the member functions inherited from enumerable are defined
            in the enumerable class and their documentation is not repeated in each 
            container's documentation.  This includes the size() member function in each
            container.
         </p>

                  This implementation is done using a doubly linked list in the shape of a ring.  
                  It will remember the last element accessed(or added or removed) and give O(1)

                  accessing(or adding or removing) a random element will take O(n) and in the worst

            This object represents a mapping of items of type domain onto items of type range. 
            The difference between this object and the normal <a href="#map">map</a> object is that it does not support adding
            or removing individual objects from itself.  This allows implementations to focus on using less memory and 
            achieving faster searching.

                  This extension gives static_sets the ability to compare themselves using operator&lt; and 
                  operator==.  Thus they can be used in the other container classes that require 
                  this ability. (maps, static_sets, etc.)

         <description>
           This is a 2D matrix object that enables you to write code that deals with
           matrices using a simple syntax similar to what can be written in MATLAB.  It is implemented using 
           the <a href="matrix_expressions_ex.cpp.html">expression templates</a> technique which allows it to eliminate the 
           temporary matrix objects that would normally be returned from expressions 
           such as M = A+B+C+D;  Normally each invocation of the + operator would 
           construct and return a temporary matrix object but using this technique 
           we can avoid creating all these temporary objects and receive a large speed boost.
           <p>
           This object is also capable of using BLAS and LAPACK libraries such as ATLAS or the Intel
           MKL when available.   To enable BLAS support all you have to do is #define 
           DLIB_USE_BLAS and then make sure you link your application with your 
           BLAS library.  Similarly, to enable LAPACK support just #define DLIB_USE_LAPACK and 
           link to your LAPACK library.  Finally, the use of BLAS and LAPACK is transparent to 
           the user, that is, the dlib matrix object uses BLAS and LAPACK internally to optimize 
           various operations while still allowing the user to use a simple MATLAB like syntax.  
           </p>
           <p>
           Note that the cmake files that come with dlib know how to link a project with ATLAS or
           the Intel MKL if you are building on a linux system.  The cmake files may also 
           work in a few other cases as well but I haven't tested any others.   But in any
           case, by no means are you required to use the dlib cmake files. 
           </p>
           <p>
              It is also worth noting that all the preconditions of every function 
              related to the matrix object are checked by <a href="metaprogramming.html#DLIB_ASSERT">DLIB_ASSERT</a>
              statements and thus can be enabled by #defining ENABLE_ASSERTS or DEBUG.  Doing
              this will cause your program to run slower but should catch any usage errors. 
           </p>
           <p>
              Finally, you don't need to #include anything to get the matrix extensions listed below.  
              They are included by the <a href="dlib/matrix.h.html">dlib/matrix.h</a> file for you.

            This object is a simple wrapper around the std::vector object.  It 
            provides an identical interface but also checks the preconditions of
            each member function.  That is, if you violate a requires
            clause the dlib::fatal_error exception is thrown.
