Re: [ALACPP] boost binding a const ref? |

You want a reference to a const object, not a const reference to an object. "Const reference" is a convenient misnomer for reference to a const object; references -- unlike pointers -- are implicitly const. > { > // do Something > } > }; > > and some more code that looks like this: > > ... > > Foo thing; > > MyDoSomethingPtr = boost::bind<SomeType const&>(&Foo::doSomething, this, ^^^^^^^^^^^^^^^ You shouldn't need this, unless your compiler is dumber than VC6. > _1); What type is MyDoSomethingPtr? Also, remember that references can bite you in the ass when using bind. You may want boost::ref or boost::cref. I.E., MyDoSomethingPtr = boost::bind(&Foo::doSomething, this, boost::cref(_1)); Jon -- Jon Stewart stew1@xxxxxxxxxxx _______________________________________________ alacpp mailing list alacpp@xxxxxxxxxxx http://lists.ellipsis.cx/mailman/listinfo/alacpp
