The type of the target function is allowed to be const qualified or a reference.
|

Const qualification is preserved and propagated appropriately (in other

words, only const versions of <tt class="literal">operator()</tt> can be used
|
||||
words, only const versions of <code class="literal">operator()</code> can be used
|
||||
for a target function object that is const or, if the target function object
|
||||
is held by value, the adapter is const - these semantics have nothing to
|
||||
do with the const qualification of a member function, which is referring
|
||||
to the type of object pointed to by <tt class="literal">this</tt> which is specified
|
||||
to the type of object pointed to by <code class="literal">this</code> which is specified
|
||||
with the first element in the sequence passed to the adapter).

</p>
|

<p>
|
||||
If the target function is a pointer to a members function, the corresponding
|
||||
object can be specified as a reference, pointer, or smart pointer. In case
|
||||
of the latter, a freestanding <tt class="literal">get_pointer</tt> function must
|
||||
be defined (Boost provides this function for <tt class="literal">std::auto_ptr</tt>
|
||||
and <a href="http://www.boost.org/libs/smart_ptr/shared_ptr.htm" target="_top"><tt class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">shared_ptr</span></tt></a>).

of the latter, a freestanding <code class="literal">get_pointer</code> function must

|
||||
</p>
|
||||
<p>
|
||||
The target function must not be a pointer to a member object (dereferencing
|
||||
such a pointer without returning anything does not make sense, so this
|
||||
case is not implemented).
