Detailed Description

A geographic (ellipsoidal) 2d linestring.

The linestring follows the geodetic between each pair of points.

Constructor & Destructor Documentation

◆ Geographic_linestring()

gis::Geographic_linestring::Geographic_linestring ( )
inline

Member Function Documentation

◆ accept()

bool gis::Geographic_linestring::accept ( Geometry_visitor v)
overridevirtual

Applies a hierarchical visitor to this geometry.

See also
gis::Geometry_visitor
Parameters
vA hierarchical visitor.
Return values
trueThe execution was aborted by the visitor.
falseThe execution completed.

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ back() [1/2]

const Geographic_point& gis::Geographic_linestring::back ( ) const
inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ back() [2/2]

Geographic_point& gis::Geographic_linestring::back ( )
inlineoverridevirtual

Returns the last point of the linestring.

Returns
Last point of linestring

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ begin() [1/2]

const_iterator gis::Geographic_linestring::begin ( void  ) const
inlinenoexcept

◆ begin() [2/2]

iterator gis::Geographic_linestring::begin ( void  )
inlinenoexcept

◆ clear()

void gis::Geographic_linestring::clear ( )
inlineoverridevirtualnoexcept

Removes all points from the linestring.

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ clone()

Geographic_linestring* gis::Geographic_linestring::clone ( ) const
inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ coordinate_system()

Coordinate_system gis::Geographic_linestring::coordinate_system ( ) const
inlineoverridevirtual

Gets the coordinate system.

Returns
The coordiante system type.

Implements gis::Geometry.

Reimplemented in gis::Geographic_linearring.

◆ empty()

bool gis::Geographic_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
trueThe linestring is empty.
falseThe linestring is not empty.

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ front() [1/2]

const Geographic_point& gis::Geographic_linestring::front ( ) const
inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ front() [2/2]

Geographic_point& gis::Geographic_linestring::front ( )
inlineoverridevirtual

Returns the first point of the linestring.

Returns
First point of linestring

Implements gis::Linestring.

void gis::Geographic_linestring::pop_front ( )
inlineoverridevirtual

Removes a point from the front of the linestring.

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ push_back() [1/2]

void gis::Geographic_linestring::push_back ( const Point pt)
overridevirtual

Adds a point to the end of the linestring.

Parameters
ptThe point to add.

Implements gis::Linestring.

Reimplemented in gis::Geographic_linearring.

◆ size()

std::size_t gis::Geographic_linestring::size ( ) const
inlineoverridevirtual

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

Returns
Number of points in the linestring.
