Function Documentation

Construct()

template<CFunctorObject Initializer, typename... Args, typename ResultArg = TFunction_Arg<Initializer, 0>, typename Result = std::decay_t<ResultArg>>
requires std::is_lvalue_reference_v<ResultArg>

Result Mcro::Construct::Construct	(	Initializer &&	init,
		Args &&...	args )

Simply makes a new object and allows to initialize it in place with a lambda function. The object type is derived from the first argument of the initializer lambda function. Usage:

using namespace Mcro::Construct;
 
auto myObject = Construct([](MyObject& _)
{
    _.Foo = 42;
    _.Initialize();
    // etc...
});
static_assert(std::is_same_v<decltype(myObject), MyObject>);

Parameters

init	A lambda function with a single l-value reference parameter of the object type to initialize.
args

Returns

A new instance of the object.

Remarks

The C++ 20 designated initializers with named arguments has annoying limitations, therefore this exists

ConstructNew()

template<CFunctorObject Initializer, typename... Args, typename ResultArg = TFunction_Arg<Initializer, 0>, typename Result = std::decay_t<ResultArg>>
requires std::is_lvalue_reference_v<ResultArg>

Result * Mcro::Construct::ConstructNew	(	Initializer &&	init,
		Args &&...	args )

Simply makes a new object on the heap and allows to initialize it in place with a lambda function. The object type is derived from the first argument of the initializer lambda function. Usage:

using namespace Mcro::Construct;
 
auto myObject = ConstructNew([](MyObject& _)
{
    _.Foo = 42;
    _.Initialize();
    // etc...
});
static_assert(std::is_same_v<decltype(myObject), MyObject*>);

Parameters

init	A lambda function with a single l-value reference parameter of the object type to initialize.
args

Returns

A pointer to the object instance on heap.

Remarks

The C++ 20 designated initializers with named arguments has annoying limitations, therefore this exists
