|

<p>libstdc++ strives to implement all of TR1.
|
||||
The libstdc++ implementation status of the TR1 draft is listed in
|
||||
<a href="../ext/tr1.html">this page</a>.
|
||||
An <a href="../ext/tr1.html">overview</a> of the implementation status
|

is available.
|

</p>
|
||||
|
||||
<p>Briefly, the features of TR1 and the current status are:
|
||||
</p>
|
||||
|
||||
<p><strong>Unordered containers - Complete -</strong>
|
||||
The unordered_set, unordered_map, unordered_multiset, and unordered_multimap containers
|
||||
are hashed versions of the map, set, multimap, and multiset containers respectively.
|
||||
These classes are suitable replacements for the SGI STL hash_map and hash_set extensions.

|
||||
</p>
|
||||
|
||||
<p><strong>Reference-counted smart pointers - Complete -</strong>
|
||||
The shared_ptr and weak_ptr allow several object to know about a pointer and whether it is valid.
|
||||
When the last reference to the pointer is destroyed the pointer is freed.

|
||||
</p>
|
||||
|
||||
<p><strong>Type traits - Complete -</strong>
|
||||
The type_traits class gives templates the ability to probe information about the input type
|
||||
and enable type-dependent logic to be performed without the need of template specializations.

The tuple class implements small heterogeneous arrays. This is an enhanced pair.

text with return of subexpressions.

<p><strong>Special functions - Under construction - </strong>
|
||||
Twenty-three mathematical functions familiar to physicists and engineers are included:
|
||||
cylindrical and spherical Bessel and Neumann functions, hypergeometric functions,
|
||||
Laguerre polynomials, Legendre functions, elliptic integrals, exponential integrals
|
||||
and the Riemann zeta function all for your computing pleasure.

<p><strong>C99 compatibility - Under construction - </strong>
|
