◆ Index_range

template<size_t MIN, size_t MAX>

using visioncpp::internal::tools::tuple::Index_range = typedef typename RangeBuilder<MIN, MAX>::type

IndexRange that returns a index from range of [MIN, MAX).

◆ append() [1/2]

template<typename... Args1, typename... Args2>

Tuple<Args1..., Args2...> visioncpp::internal::tools::tuple::append	(	internal::tools::tuple::Tuple< Args1... >	t1,
		internal::tools::tuple::Tuple< Args2... >	t2
	)

append

Deduction function of the append_impl for the append of the tuple t2 to the t1 tuple. The Index_range for both tuple is automatically generated.

Template Parameters

Args1...	The type of the t1 tuple.
Args2...	The type of the t2 tuple.

Parameters

t1	Is the tuple on which we want to append the t2 tuple.
t2	Is the tuple to be appended.

Returns: Tuple<Args1..., Args2...>

◆ append() [2/2]

template<typename... Args, typename T >

Tuple<Args..., T> visioncpp::internal::tools::tuple::append	(	Tuple< Args... >	t,
		T	a
	)

append

the deduction function for append_impl that automatically generates the Index_range.

Template Parameters

Args...	the type of the elements inside the tuple t.
T	the type of the new element that is going to be added at the end of the returned tuple.

Parameters

t	the tuple on which we want to append a.
a	the new elements that are going to be added to the returned tuple.

Returns: Tuple<Args..., T>

append_impl

Unpacks the elements of the input tuple t and creates a new tuple by adding the element a at the end of it.

Template Parameters

Args...	the type of the elements inside the tuple t.
T	the type of the new element that is going to be added at the end of the returned tuple.
I...	is the list of indices from [0 to sizeof...(t)) range.

Parameters

t	the tuple on which we want to append a.
a	the new elements that are going to be added to the returned tuple.

Returns: Tuple<Args..., T>

		internal::tools::tuple::Index_list< I2... >
	)

append_impl

This is a specialisation of the append_impl for the concatenation of the t2 tupe at the end of the t1 tuple. Both tuples are unpacked. Index_range is generated for each of them and output tuple T is created. The return tuple contains both elements of t1 and t2 tuples.

Template Parameters

Args1...	The type of the t1 tuple.
Args2...	The type of the t2 tuple.
I1...	The list of the indices from [0 to sizeof...(t1)) range.
I2...	The list of the indices from [0 to sizeof...(t2)) range.

Parameters

t1	Is the tuple on which we want to append the t2 tuple.
t2	Is the tuple to be appended.
