Detailed Description

Function Documentation

getM()

double geos::geom::CoordinateSequence::getM ( std::size_t  index ) const

inline

Returns ordinate M of the specified coordinate.

Parameters

index

Returns

the value of the M ordinate in the index'th coordinate, or NaN if the CoordinateSequence does not store M values

getOrdinate()

double geos::geom::CoordinateSequence::getOrdinate	(	std::size_t	index,
		std::size_t	ordinateIndex
	)		const

Returns the ordinate of a coordinate in this sequence. Ordinate indices 0 and 1 are assumed to be X and Y. Ordinates indices greater than 1 have user-defined semantics (for instance, they may contain other dimensions or measure values).

Parameters

index	the coordinate index in the sequence
ordinateIndex	the ordinate index in the coordinate (in range [0, dimension-1])

getX()

double geos::geom::CoordinateSequence::getX ( std::size_t  index ) const

inline

Returns ordinate X (0) of the specified coordinate.

Parameters

index

Returns

the value of the X ordinate in the index'th coordinate

getY()

double geos::geom::CoordinateSequence::getY ( std::size_t  index ) const

inline

Returns ordinate Y (1) of the specified coordinate.

Parameters

index

Returns

the value of the Y ordinate in the index'th coordinate

getZ()

double geos::geom::CoordinateSequence::getZ ( std::size_t  index ) const

inline

Returns ordinate Z of the specified coordinate.

Parameters

index

Returns

the value of the Z ordinate in the index'th coordinate, or NaN if the CoordinateSequence does not store Z values

operator[]() [1/2]

Coordinate & geos::geom::CoordinateSequence::operator[] ( std::size_t  i )

inline

Returns a reference to Coordinate at i

operator[]() [2/2]

const Coordinate & geos::geom::CoordinateSequence::operator[] ( std::size_t  i ) const

inline

Returns a read-only reference to Coordinate at i

setM()

void geos::geom::CoordinateSequence::setM ( std::size_t  index, double  m  )

inline

Set the M value of the specified coordinate.

Has no effect if the CoordinateSequence does not store M values.

Parameters

index
m	the new M value

setX()

void geos::geom::CoordinateSequence::setX ( std::size_t  index, double  x  )

inline

Set the X value of the specified coordinate.

Parameters

index
x	the new X value

setY()

void geos::geom::CoordinateSequence::setY ( std::size_t  index, double  y  )

inline

Set the Y value of the specified coordinate.

Parameters

index
y	the new Y value

setZ()

void geos::geom::CoordinateSequence::setZ ( std::size_t  index, double  z  )

inline

Set the Z value of the specified coordinate.

Has no effect if the CoordinateSequence does not store Z values.

Parameters

index
z	the new Z value
