Constructor & Destructor Documentation

Vector_d() [1/2]

template<typename DimensionTag >

CGAL::Epick_d< DimensionTag >::Vector_d::Vector_d	(	double	x0,
		double	x1,
			...
	)

introduces a vector with coordinates (x0, x1, ...) where the number of coordinates matches the dimension.

Precondition

DimensionTag is a fixed dimension, not Dynamic_dimension_tag.

Vector_d() [2/2]

template<typename DimensionTag >

template<typename InputIterator >

CGAL::Epick_d< DimensionTag >::Vector_d::Vector_d	(	InputIterator	first,
		InputIterator	end
	)

introduces a vector with coordinate set [first,end).

Precondition

If DimensionTag is a fixed dimension, it matches std::distance(first,end).

Template Parameters

InputIterator

has its value type that is convertible to double.

)

const

returns the i-th coordinate of a vector.

Precondition

i is non-negative and less than the dimension.

bool operator!= ( Vector_d  , Vector_d    )

friend

returns whether the vectors are distinct.

This may not be safe if the vectors are the result of inexact constructions.

operator==

bool operator== ( Vector_d  , Vector_d    )

friend

returns whether the vectors coincide.

This may not be safe if the vectors are the result of inexact constructions.
