Detailed Description

Gets element from an IntSeq according to specific pattern.

Definition in file IntSeqGetEl.hpp.

Typedef Documentation

template<int N, typename Is >

using SUNphi::IntSeqGetAllButFirstN = typedef decltype(_IntSeqGetAllButFirstN<N>(Is{}))

Returns all the IntSeq but the first N elements

Gives visibility to the internal implementation

Definition at line 38 of file IntSeqGetEl.hpp.

template<int Tail, bool ReturnNotPresent, typename Pos , typename Head >

using SUNphi::IntSeqGetElsAfterAppending = typedef decltype(_IntSeqGetElsAfterAppending<Tail,ReturnNotPresent>(Pos{},Head{}))

Modified extraction of an element in an IntSeq after appending a value

Returns an IntSeq containing the element of all positions Pos in the passed IntSeq, after appending a given value to it. If asked, all the NOT_PRESENT are replaced with empty value.

Definition at line 101 of file IntSeqGetEl.hpp.

Function Documentation

template<int N, int Head, int... Tail>

decltype(auto) SUNphi::_IntSeqGetAllButFirstN

(

IntSeq< Head, Tail... >

)

Returns all the IntSeq but the first N elements

Recursive internal implementation

template<int Tail, bool ReturnNotPresent, int Pos, int... Head>

decltype(auto) constexpr SUNphi::_IntSeqGetElAfterAppending

(

IntSeq< Head... >

)

Modified extraction of an element in an IntSeq after appending a value

Returns an IntSeq containing the element of position Pos in the passed IntSeq, after appending a given value to it. If asked, the returned NOT_PRESENT is replaced with empty value.

int a=
    posInIntSeqAfterAppending<2,4>(IntSeq<0,1,2,3){}>; // 2
