In this way the <tt><A HREF="array2D.html" >array2D</A></tt> storage type is the most flexible, since many different types of 1-D containers can be used in conjunction with this class. The 1-D containers include <tt><A HREF="linked_list.html" >linked_list</A></tt> (<A HREF="sparse1D.html" >sparse1D</A><std::list>), <tt><A HREF="tree.html" >tree</A></tt> (<A HREF="sparse1D.html" >sparse1D</A><std::set>), <tt><A HREF="dense.html" >dense</A></tt> (std::vector), <tt><A HREF="sparse_pair.html" >sparse_pair</A></tt> (<A HREF="sparse1D.html" >sparse1D</A><std::vector>), and <tt><A HREF="compressed.html" >compressed</A></tt> (mtl::<A HREF="compressed1D.html" >compressed1D</A>). One special feature of the <tt><A HREF="array2D.html" >array2D</A></tt> is that one can swap and assign the Vectors inside the <A HREF="array.html" >array</A> in constant time, as mentioned in the <A HREF="array.html" >array</A> interface description. The backbone container of the <A HREF="array2D.html" >array2D</A> is not implemented with std::vector due to some subtle interactions between <A HREF="copy.html" >copy</A>/default constructors and handle objects.
