Re: [Boost-users] identical boost expression used in different parts of the code - looking for an alias

e r wrote:

hi boost::bind( &A::f, _1 )

in different parts of my code. how can i define an alias for this expression?

i'm thinking of using something like

some_type* fo = new boost::bind(&A::f,_1);

and use *fo in place of boost::bind(...). is this crazy? what should some_type be?

Normally the easiest thing to do is to put it into a boost::function object. The correct type depends on the parameter to &A::f and the return type. Assuming that it is this: R A::f( B ) then something like this should work: boost::function< R ( B ) > do_f( boost::bind( &A::f, _1 ) ); R my_r = do_f( a_B ); K
