Detailed Description

template<typename T, size_t N>
class iolink::Vector< T, N >

An arithmetic vector.

Template Parameters
TThe type wrote in the vector.
NThe size, or number of dimension of the vector.

Aliases can be used to made this class more practical to use. They use the following convention: VectorNX Where N is the size and X the type. The types currently available are:

  • U8 and I8 respectively for unsigned and signed 8bits integers.
  • U16 and I16 respectively for unsigned and signed 16bits integers.
  • U32 and I32 respectively for unsigned and signed 32bits integers.
  • U64 and I64 respectively for unsigned and signed 64bits integers.
  • F for single precision floats.
  • D for double precision floats.

Examples:

  • Vector2i32: 2 dimensional 32bits signed integer.
  • Vector3f: 3 dimensionnal single precision float.

Constructor & Destructor Documentation

◆ Vector() [1/4]

template<typename T , size_t N>
iolink::Vector< T, N >::Vector ( std::initializer_list< ValueType >  init)

Create a vector with the values contained in a bracket list.

Exceptions
InvalidArgumentwhen initializing with a wrong number of elements

◆ Vector() [2/4]

template<typename T , size_t N>
iolink::Vector< T, N >::Vector ( const VectorX< ValueType > &  other)

Build a Vector from a VectorX of same type.

If the VectorX has a size different of N, behavior is undefined.

◆ Vector() [3/4]

template<typename T , size_t N>
iolink::Vector< T, N >::Vector ( const VectorX< ValueType > &  other,
ValueType  padding 
)

Build a vector from a VectorX of same type.

Parameters
otherVectorX to use to build the new vector
paddingValue to put at the end of vector to fill missing values. Fox example, Vector4({4, 5}, 0) will create the Vector {4, 5, 0, 0}.

◆ Vector() [4/4]

template<typename T , size_t N>
template<typename U >
iolink::Vector< T, N >::Vector ( const Vector< U, N > &  other)
inlineexplicit

Build a vector from a vector storing another type.

Template Parameters
UThe type of the source vector.
Parameters
otherThe vector to convert.

Member Function Documentation

◆ createUniform()

template<typename T , size_t N>
static Vector iolink::Vector< T, N >::createUniform ( ValueType  value)
static

Create a vector with the given value for all components.

Parameters
valueThe value wich the vector's data will be filled.

◆ cross()

template<typename T , size_t N>
Vector iolink::Vector< T, N >::cross ( const Vector< T, N > &  v) const

Cross product of two vectors.

Work only for vectors of size 3.

◆ length()

template<typename T , size_t N>
double iolink::Vector< T, N >::length ( ) const

Returns the vector's norm.

Specifically, it is the L1 norm that's computed here.

◆ squaredLength()

template<typename T , size_t N>
double iolink::Vector< T, N >::squaredLength ( ) const

Returns the vector's norm, squared.

Specifically, it is the L1 norm that's computed here.
