Uno/Cpp/Snippet/Function accepting any kind of parameters
From Apache OpenOffice Wiki
Callee:
// This function is environment specialized on "c++<purpose>*". void takeAnyObject(uno::Reference<...> const & rObj) { // We need to remember the callers environment, to "map-out/in" // the parameters and return values properly. uno::Environment outerEnv(uno::getCurrent()); // We now activate (enter) the "c++:unsafe" environment. // Note: Any other environment suiteable for "MyUnsafeObject" would work as well. cppu::EnvGuard unsafeGuard(uno::Environment(rtl::OUString(RTL_CONSTASCII_PARAM("c++:unsafe")))); // We "mapIn" the parameter. uno::Reference<...> unsafeEnv_Obj.set(cppu::mapIn(rObj, outerEnv), SAL_NO_ACQUIRE); // MyUnsafeObj has a C++ [[Uno/Term/Object Binary Interface|OBI]] and is thread-unsafe unsafeEnv_Obj->set(new MyUnsafeObject()); }
Caller:
... { // Whatever "c++<purpose>*" we enter, the parameter passed to "takeAnyObject" will // always match. cppu::EnvGuard cppDebug_Guard(rtl::OUString(RTL_CONSTASCII_PARAM("c++:debug"))); uno::Reference<...> obj(...); takeAnyObject(obj); } ...
