An n-ary < a class = "link" href = "../concepts/poly.html" title = "Polymorphic Function Object" > Polymorphic Function
Object< / a > adapter template for an unary < a class = "link" href = "../concepts/poly.html" title = "Polymorphic Function Object" > Polymorphic
2009-02-22 06:27:12 +00:00
Function Object< / a > target function. When called, its arguments are
2009-09-25 00:21:53 +00:00
bundled to a < a class = "link" href = "../../sequence/concepts/random_access_sequence.html" title = "Random Access Sequence" > Random

Access Sequence< / a > of references that is passed to the target function
object.

The nullary overload of the call operator can be removed by setting the
2009-09-25 00:21:53 +00:00
second template parameter to < code class = "computeroutput" > < span class = "keyword" > false< / span > < / code > ,
2009-02-22 06:27:12 +00:00
which is very useful if the result type computation would result in a compile
error, otherwise (nullary call operator's prototypes can't be templates
and thus are instantiated as early as the class template).
< / p >
< p >
Only LValue arguments are accepted. To overcome this limitation, apply
< a href = "http://www.boost.org/libs/functional/forward/doc/html/index.html" target = "_top" > Boost.Functional/Forward< / a > .
< / 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
2009-09-25 00:21:53 +00:00
words, only const versions of < code class = "literal" > operator()< / code > can be used
2009-02-22 06:27:12 +00:00
if the target function object is const - or, in case the target function
object is held by value, the adapter is const.
