Detailed Description

type template definitions

Typedef Documentation

_if_

template<bool B, typename T , typename F >

using DSC::_if_ = typedef typename __if__<B,T,F>::type

Decides type based on a boolean expression.

Template Parameters

B	boolean expression
T	type if B is true
F	type if B is false

if B is true, then _if_<B,T,F> evaluates to T, otherwise it evaluates to F

Equivalent of std::conditional

_if_< (2>3), int, short > x; // <=> short x; 

_no_ref_

template<typename T >

using DSC::_no_ref_ = typedef typename __no_ref__<T>::type

gets rid of type reference

Equivalent of std::remove_reference

_no_ref_<int> x;   // <=> int x; 
_no_ref_<int&> x;  // <=> int x; 
_no_ref_<int&&> x; // <=> int x; 

uint_best_fit

template<unsigned int C>

using DSC::uint_best_fit = typedef _if_< C<256, unsigned char, _if_<C<65536, unsigned short, unsigned int> >

Chooses the smallest unsigned integer type that fits a constant.

Template Parameters

C	an unsigned constant

• if 0<=C<256, then uint_best_fit<C> is 8-bit
• if 256<=C<65536, then uint_best_fit<C> is 16-bit
• if 65536<=C, then uint_best_fit<C> is 32-bit

Function Documentation

_move_()

template<class T >

_no_ref_< T > && DSC::_move_

(

T &&

arg

)

Creates rvalue reference from object (useful in move semantics)

Parameters

[in]

arg

the target object

Returns

rvalue reference (&&) to object

Equivalent of std::move
