Constructor & Destructor Documentation

◆ RefValue()

RefValue ( TT &... refs )

inlineexplicit

Constructor from reference values.

Parameters

[in] refs K references to values that are stored in the order of the parameters.

Member Function Documentation

◆ Cast()

Ty Cast ( ) const

inlinenoexcept

Cast to any type, for which a set<size_t>(Ty) function exists.

Template Parameters

Ty	Target type, for which a Cvb::set<size_t>(Ty) function exists.

Returns: A newly constructed object of Ty.

◆ NumValues()

static constexpr const size_t NumValues ( )

inlinestaticconstexprnoexcept

Get number of values stored in this RefValue.

Returns: size_t The number of values K.

◆ operator=() [1/2]

RefValue< T, K > & operator= ( const T(&) list[N] )

inlinenoexcept

Assignment from a N-element initializer list or array. The values pointed to by this class are overwritten by those of the initializer list.

Template Parameters

N	The number of values. Must be equal to K.

Parameters

[in] list N-element initializer list or array.

Returns: Reference to this RefValue.

◆ operator=() [2/2]

RefValue< T, K > & operator= ( const Ty & other )

inlinenoexcept

Assignment from any type, for which get<size_t>(Ty) function exists. The values pointed to by this class are overwritten by those of other.

Parameters

[in] other Object of any type Ty to copy values from. A get<size_t>(Ty) function has to be provided elsewhere and should be defined for 0,..,K-1.

Returns: Reference to this RefValue.

◆ operator[]() [1/2]

T operator[] ( size_t i ) const

inlinenoexcept

Element access.

Parameters

[in] i The index of the requested element.

Returns: T The value of the i-th element.

◆ operator[]() [2/2]

T & operator[] ( size_t i )

inlinenoexcept

Mutable element access.

Parameters

[in] i The index of the requested element.

Returns: T The reference to the i-th element.

◆ W() [1/2]

T W ( ) const

inlinenoexcept

Get const value of the fourth (w) value.

Returns: The w value.

◆ W() [2/2]

T & W ( )

inlinenoexcept

Get reference to the fourth (w) value.

Returns: Reference to the w value.

◆ X() [1/2]

T X ( ) const

inlinenoexcept

Get const value of the first (x) value.

Returns: The x value.

◆ X() [2/2]

T & X ( )

inlinenoexcept

Get reference to the first (x) value.

Returns: Reference to the x value.

◆ Y() [1/2]

T Y ( ) const

inlinenoexcept

Get const value of the second (y) value.

Returns: The y value.

◆ Y() [2/2]

T & Y ( )

inlinenoexcept

Get reference to the second (y) value.

Returns: Reference to the y value.

◆ Z() [1/2]

T Z ( ) const

inlinenoexcept

Get const value of the third (z) value.

Returns: The z value.

◆ Z() [2/2]

T & Z ( )

inlinenoexcept

Get reference to the third (z) value.

Returns: Reference to the z value.
