Public Functions Documentation

function Interval [1/4]

SFCGAL::detail::Interval::Interval () 

default constructor (empty interval)

---

function Interval [2/4]

SFCGAL::detail::Interval::Interval (
    const double & value
) 

collapsed interval constructor

---

function Interval [3/4]

SFCGAL::detail::Interval::Interval (
    const double & v1,
    const double & v2
) 

constructor with two values

---

function Interval [4/4]

SFCGAL::detail::Interval::Interval (
    const Interval & other
) 

copy constructor

---

function expandBy

void SFCGAL::detail::Interval::expandBy (
    const double & d
) 

expand the interval

Warning:

no effect if isEmpty()

---

function expandToInclude [1/2]

void SFCGAL::detail::Interval::expandToInclude (
    const Interval & other
) 

expand the interval to include an other interval.

Warning:

no effect if other.isEmpty()

---

function expandToInclude [2/2]

void SFCGAL::detail::Interval::expandToInclude (
    const double & value
) 

expand the interval to include a value

Warning:

no effect if value is NaN

---

function intersects

bool SFCGAL::detail::Interval::intersects (
    const Interval & other
) const

test if this intersects other

---

function isEmpty

bool SFCGAL::detail::Interval::isEmpty () const

indicates if the interval is empty

---

function lower

inline const double & SFCGAL::detail::Interval::lower () const

returns the lower value

---

function operator!=

bool SFCGAL::detail::Interval::operator!= (
    const Interval & other
) const

compare two intervals

Warning:

false for empty intervals

---

function operator=

Interval & SFCGAL::detail::Interval::operator= (
    const Interval & other
) 

assign operator

---

function operator==

bool SFCGAL::detail::Interval::operator== (
    const Interval & other
) const

compare two intervals

Warning:

true for empty intervals

---

function upper

inline const double & SFCGAL::detail::Interval::upper () const

returns the upper value

---

function width

inline double SFCGAL::detail::Interval::width () const

returns the with of the interval
