Deferred Callable Object

Deferred Callable Object

Description

Callable Object types that work with Boost.ResultOf to determine the result of a call.

Refinement of

Callable Object

Notation

F: A possibly const qualified Deferred Callable Object type
A1 ...AN: Argument types
a1 ...aN: Objects or references to objects with types A1 ...AN
T1 ...TN: Ti is Ai & if ai is an LValue, same as Ai, otherwise

Expression requirements

Expression	Type
`boost::result_of< F(T1 ...TN) >::type`	Result of a call with `A1 ...AN`-typed arguments

Models

Polymorphic Function Object types
member (function or data) pointer types

Examples

& a_free_function
& a_class::a_static_member_function
& a_class::a_nonstatic_data_member
& a_class::a_nonstatic_member_function
std::less<int>()
// using namespace boost;
bind(std::less<int>(), _1, 5)
// Note: Boost.Lambda expressions don't work with __boost_result_of__
