The problem is that in order to 23 // discern the correct specialization of Callback<>, Bind would need to 24 // unwrap the function signature to determine the signature's arity, and 25 // whether or not it is a method. 26 // 27 // Each unique combination of (arity, function_type, num_prebound) where 28 // function_type is one of {function, method, const_method} would require 29 // one specialization. We eventually have to do a similar number of 30 // specializations anyways in the implementation (see the FunctionTraitsN, 31 // classes). However, it is avoidable in Bind if we return the result 32 // via an indirection like we do below. 33 34 namespace base { 35 36 template <typename Sig> 37 internal::InvokerStorageHolder<internal::InvokerStorage0<Sig> > 38 Bind(Sig f) { 39 return internal::MakeInvokerStorageHolder( 40 new internal::InvokerStorage0<Sig>(f)); 41 } 42 43 template <typename Sig, typename P1> 44 internal::InvokerStorageHolder<internal::InvokerStorage1<Sig,P1> > 45 Bind(Sig f, const P1& p1) { 46 return internal::MakeInvokerStorageHolder( 47 new internal::InvokerStorage1<Sig, P1>( 48 f, p1)); 49 } 50 51 template <typename Sig, typename P1, typename P2> 52 internal::InvokerStorageHolder<internal::InvokerStorage2<Sig,P1, P2> > 53 Bind(Sig f, const P1& p1, const P2& p2) { 54 return internal::MakeInvokerStorageHolder( 55 new internal::InvokerStorage2<Sig, P1, P2>( 56 f, p1, p2)); 57 } 58 59 template <typename Sig, typename P1, typename P2, typename P3> 60 internal::InvokerStorageHolder<internal::InvokerStorage3<Sig,P1, P2, P3> > 61 Bind(Sig f, const P1& p1, const P2& p2, const P3& p3) { 62 return internal::MakeInvokerStorageHolder( 63 new internal::InvokerStorage3<Sig, P1, P2, P3>( 64 f, p1, p2, p3)); 65 } 66 67 template <typename Sig, typename P1, typename P2, typename P3, typename P4> 68 internal::InvokerStorageHolder<internal::InvokerStorage4<Sig,P1, P2, P3, P4> > 69 Bind(Sig f, const P1& p1, const P2& p2, const P3& p3, const P4& p4) { 70 return internal::MakeInvokerStorageHolder( 71 new internal::InvokerStorage4<Sig, P1, P2, P3, P4>( 72 f, p1, p2, p3, p4)); 73 } 74 75 template <typename Sig, typename P1, typename P2, typename P3, typename P4, 76 typename P5> 77 internal::InvokerStorageHolder<internal::InvokerStorage5<Sig,P1, P2, P3, P4, 78 P5> > 79 Bind(Sig f, const P1& p1, const P2& p2, const P3& p3, const P4& p4, 80 const P5& p5) { 81 return internal::MakeInvokerStorageHolder( 82 new internal::InvokerStorage5<Sig, P1, P2, P3, P4, P5>( 83 f, p1, p2, p3, p4, p5)); 84 } 85 86 template <typename Sig, typename P1, typename P2, typename P3, typename P4, 87 typename P5, typename P6> 88 internal::InvokerStorageHolder<internal::InvokerStorage6<Sig,P1, P2, P3, P4, 89 P5, P6> > 90 Bind(Sig f, const P1& p1, const P2& p2, const P3& p3, const P4& p4, 91 const P5& p5, const P6& p6) { 92 return internal::MakeInvokerStorageHolder( 93 new internal::InvokerStorage6<Sig, P1, P2, P3, P4, P5, P6>( 94 f, p1, p2, p3, p4, p5, p6)); 95 } 96 97 } // namespace base 98 99 #endif // BASE_BIND_H_ 100
