   <title>Containers</title>

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

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

         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.
         </p>

         <p>
         To use any of these containers all you need to do is #include the file indicated in the 
         short section about the component you would like to use. Then pick which implementation you 
         would like and typedef it to something nice. Here is an example of creating a typedef for 
         a set of integers using the first kernel implementation. <br/>
         <tt>typedef dlib::set&lt;int&gt;::kernel_1a set_of_ints;</tt> 
         </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 object is just like a C style array and the accessor functions operate

               <description> 
                  This implementation is done using an array of pointers, each of which point to 
                  small sections of the array. This implementation allows the array to use only 
                  about as much memory as it needs at any given time.
                  It does not use the <a href="other.html#memory_manager">memory_manager</a> at all.

                  This implementation is done using a single array of max_size() elements.  So this
                  is just a simple layer on top of a C style array.
                  It uses the <a href="other.html#memory_manager">memory_manager</a> for all 
                  memory allocations.

                        This is implemented by creating a new bigger array if max_size() isn't big enough,

            <p>
                The weak_ptr class template stores a weak reference to an object that is 
                already managed by a shared_ptr. To access the object, a weak_ptr can 
                be converted to a shared_ptr using the member function lock().  
            </p>

            <p>
                This is an implementation of the std::tr1::weak_ptr template from the

                Library Extensions.  The only deviation from that document is that this

                This is an implementation of a very simple templated container object.
                It contains between 0 and 31 objects where each object is listed
                explicity in the tuple's template arguments.   

            <p>
               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 matrix object.  
               So for example, you
               could declare a tuple of 3 ints using the following statement: 
               <tt>dlib::tuple&lt;int,int,int&gt; t;</tt>

                This is a implementation of the scoped_ptr class found in the Boost C++

                pointer contained within it will always be deleted.  
                
                The class does not permit copying and so does not do any kind of 
                reference counting.  Thus it is very simple and quite fast.

            This object represents an ordered sequence of items, each item is 
            associated with an integer value. The items are numbered from 0 to the number of items in the 
            sequence minus 1.

                  This is implemented as an AVL binary search tree.  
                  Accessing(or adding or removing) an element always takes O(log n) time.  
 It uses the <a href="other.html#memory_manager">memory_manager</a> for all memory allocations.

                  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) 
                  access time to the elements just left and right of it.  Aside from that, 
                  accessing(or adding or removing) a random element will take O(n) and in the worst 
                  case it will take time proportional to the size of the sequence/2.  
      <p>
                     It does not use the

                        used with sequence_kernel_2 and fairly slow when used with sequence_kernel_1

           This is a 2D matrix object.  It is implemented using the expression templates 
           technique which allows us 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 of these temporary 
           objects and receive a large speed boost.
         <p>
            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 matrix object.  
            So for example, you
            could declare a matrix of 2 rows and 3 columns using the following statement: 
            <tt>dlib::matrix&lt;float,2,3&gt; m;</tt>  
         </p>
         <p>
            It should also be noted that matrix multiplication is fastest when the two matrices
            being multiplied are not complex matrix_exp objects returned from other expressions 
            (such as other matrix multiplies).  This is because the matrix multiply operator will
            evaluate each element of the matrices it is multiplying many times, and a matrix_exp
            computes its elements' values each time they are queried.  However, the matrix multiply 
            operator is the only one that evaluates its argument's elements multiple times so you can
            stack up all the other operators however you want without any performance penalty.  If
            you want to multiply two complex matrix_exp expressions together you can easily convert them into
            fully evaluated temporary matrix objects by using the tmp() function.  For example, to
            multiply four matrices together you should use an expression such as <tt>result = tmp(a*b)*tmp(c*d);</tt>

            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.
