[[`BOOST_DEFAULTED_FUNCTION(fun, body)`][
This macro is intended to be used within a class definition in order to declare a default implementation of function `fun`.
For the compilers that do not support C++11 defaulted functions the macro will expand into an inline function definition
with the `body` implementation. For example:
``
struct my_struct
{
BOOST_DEFAULTED_FUNCTION(my_struct(), {})
};
``
is equivalent to:
``
struct my_struct
{
my_struct() = default;
};
``
or:
``
struct my_struct
{
my_struct() {}
};
``
]]
[[`BOOST_DELETED_FUNCTION(fun)`][
This macro is intended to be used within a class definition in order to declare a deleted function `fun`.
For the compilers that do not support C++11 deleted functions the macro will expand into a private function
declaration with no definition. Since the macro may change the access mode, it is recommended to use this macro
at the end of the class definition. For example:
``
struct noncopyable
{
BOOST_DELETED_FUNCTION(noncopyable(noncopyable const&))
BOOST_DELETED_FUNCTION(noncopyable& operator= (noncopyable const&))
};
``
is equivalent to:
``
struct noncopyable
{
noncopyable(noncopyable const&) = delete;
noncopyable& operator= (noncopyable const&) = delete;
};
``
or:
``
struct noncopyable
{
private:
noncopyable(noncopyable const&);
noncopyable& operator= (noncopyable const&);
};
