An unary < a href = "../concepts/poly.html" title = " Polymorphic Function

Sequence< / a > that contains the arguments for the target function.
< / p >
< 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
2009-02-22 06:27:12 +00:00
words, only const versions of < code class = "literal" > operator()< / code > can be used
2007-11-06 12:13:52 +00:00
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
2009-02-22 06:27:12 +00:00
to the type of object pointed to by < code class = "literal" > this< / code > which is specified
2007-11-06 12:13:52 +00:00
with the first element in the sequence passed to the adapter).
< / p >
< p >
If the target function is a pointer to a class members, the corresponding
object can be specified as a reference, pointer, or smart pointer. In case
2009-02-22 06:27:12 +00:00
of the latter, a freestanding < code class = "literal" > get_pointer< / code > function must
be defined (Boost provides this function for < code class = "literal" > std::auto_ptr< / code >
