An unary <a href="../concepts/poly.html" title=" Polymorphic Function
Object">Polymorphic Function
Object</a> adapter template for a <a href="../concepts/poly.html" title=" Polymorphic Function

Function Object</a> target function. It takes a <a href="../../sequence/concepts/forward_sequence.html" title="Forward

<p>
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
for an target function object that is const or, if the target function
object is held by value, the adapter is const).
