pure_out_value ---------------- Motivation ~~~~~~~~~~ This works exactly like ``out_value``, except that it will pass a default constructed object instead of converting an argument from Lua. This means that the parameter will be removed from the lua signature. Defined in ~~~~~~~~~~ .. parsed-literal:: #include <luabind/out_value_policy.hpp> Synopsis ~~~~~~~~ .. parsed-literal:: pure_out_value(index, policies = none) Parameters ~~~~~~~~~~ =============== ============================================================= Parameter Purpose =============== ============================================================= ``index`` The index of the parameter to be used as an out parameter. ``policies`` The policies used internally to convert the out parameter to Lua. ``_1`` is used as the internal index. =============== ============================================================= Example ~~~~~~~ Note that no values are passed to the calls to ``f1`` and ``f2``. .. parsed-literal:: void f1(float& val) { val = 10.f; } void f2(float\* val) { \*val = 10.f; } module(L) [ def("f", &f, **pure_out_value(_1)**) ]; Lua 5.0 Copyright (C) 1994-2003 Tecgraf, PUC-Rio > print(f1()) 10 > print(f2()) 10
