Detailed Description

A Cartesian 2d linestring.

Constructor & Destructor Documentation

Cartesian_linestring()

gis::Cartesian_linestring::Cartesian_linestring ( )

inline

Member Function Documentation

accept()

bool gis::Cartesian_linestring::accept ( Geometry_visitor *  v )

overridevirtual

Applies a hierarchical visitor to this geometry.

See also

gis::Geometry_visitor

Parameters

v	A hierarchical visitor.

Return values

true	The execution was aborted by the visitor.
false	The execution completed.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

back() [1/2]

Cartesian_point& gis::Cartesian_linestring::back ( )

back() [2/2]

const Cartesian_point& gis::Cartesian_linestring::back ( ) const

begin() [1/2]

inlinenoexcept

begin() [2/2]

const_iterator gis::Cartesian_linestring::begin ( void  ) const

inlinenoexcept

clear()

void gis::Cartesian_linestring::clear ( )

inlineoverridevirtualnoexcept

Removes all points from the linestring.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

coordinate_system()

Coordinate_system gis::Cartesian_linestring::coordinate_system ( ) const

inlineoverridevirtual

Gets the coordinate system.

Returns

The coordiante system type.

Implements gis::Geometry.

Reimplemented in gis::Cartesian_linearring.

empty()

bool gis::Cartesian_linestring::empty ( ) const

overridevirtual

Checks if the linestring is empty.

Here, the definition of empty is that the linestring does not contain any points. An invalid linestring with only one coordinate is not empty.

Return values

true	The linestring is empty.
false	The linestring is not empty.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

operator[]() [2/2]

const Cartesian_point& gis::Cartesian_linestring::operator[] ( std::size_t  i ) const

inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

push_back() [1/2]

void gis::Cartesian_linestring::push_back ( const Point &  pt )

overridevirtual

Adds a point to the end of the linestring.

Parameters

pt	The point to add.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

push_back() [2/2]

void gis::Cartesian_linestring::push_back ( Point &&  pt )

resize()

void gis::Cartesian_linestring::resize ( std::size_t  count )

inline

size()

std::size_t gis::Cartesian_linestring::size ( ) const

inlineoverridevirtual

Returns the size of (number of points in) the linestring.

Returns

Number of points in the linestring.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

Member Data Documentation

const_iterator
