The Profile Mode extension is not used by anybody, nor maintained by anybody. The containers do not support the full API specified in recent standards, and so enabling Profile Mode is not source compatible with much modern C++ code. The heuristics that would check the profile information and make useful suggestions never materialized, so it isn't useful. It should be removed.

|
||
been made with containers. Those dealing with older SGI-style
|
||
allocators are dealt with elsewhere. The remaining ones all deal
|
||
with bits:
|
||
</p><p>The old pre-standard <code class="code">bit_vector</code> class is
|
||
present for backwards compatibility. It is simply a typedef for
|
||
the <code class="code">vector<bool></code> specialization.
|
||
</p><p>The <code class="code">bitset</code> class has a number of extensions, described in the
|
||
rest of this item. First, we'll mention that this implementation of
|
||
<code class="code">bitset<N></code> is specialized for cases where N number of
|
||
bits will fit into a single word of storage. If your choice of N is
|
||
within that range (<=32 on i686-pc-linux-gnu, for example), then all
|
||
of the operations will be faster.
|
||
</p><p>There are
|
||
versions of single-bit test, set, reset, and flip member functions which
|
||
do no range-checking. If we call them member functions of an instantiation
|
||
of <code class="code">bitset<N></code>, then their names and signatures are:
|
||
</p><pre class="programlisting">
|
||
bitset<N>& _Unchecked_set (size_t pos);
|
||
bitset<N>& _Unchecked_set (size_t pos, int val);
|
||
bitset<N>& _Unchecked_reset (size_t pos);
|
||
bitset<N>& _Unchecked_flip (size_t pos);
|
||
bool _Unchecked_test (size_t pos);
|
||
</pre><p>Note that these may in fact be removed in the future, although we have
|
||
no present plans to do so (and there doesn't seem to be any immediate
|
||
reason to).
|
||
</p><p>The member function <code class="code">operator[]</code> on a const bitset returns
|
||
a bool, and for a non-const bitset returns a <code class="code">reference</code> (a
|
||
nested type). No range-checking is done on the index argument, in keeping
|
||
with other containers' <code class="code">operator[]</code> requirements.
|
||
</p><p>Finally, two additional searching functions have been added. They return
|
||
the index of the first "on" bit, and the index of the first
|
||
"on" bit that is after <code class="code">prev</code>, respectively:
|
||
</p><pre class="programlisting">
|
||
size_t _Find_first() const;
|
||
size_t _Find_next (size_t prev) const;</pre><p>The same caveat given for the _Unchecked_* functions applies here also.
