Detailed Description

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

An arithmetic vector.

Template Parameters

T	The type wrote in the vector.
N	The 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() [1/3]

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() [2/3]

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

other	VectorX to use to build the new vector
padding	Value 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() [3/3]

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

U	The type of the source vector.

Parameters

other

The 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

value

The 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.
