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]

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

inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

◆ back() [2/2]

Cartesian_point & gis::Cartesian_linestring::back ( )

inlineoverridevirtual

Returns the last point of the linestring.

Returns: Last point of linestring

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

◆ begin() [1/2]

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

inlinenoexcept

◆ begin() [2/2]

iterator gis::Cartesian_linestring::begin ( void )

inlinenoexcept

◆ clear()

void gis::Cartesian_linestring::clear ( )

inlineoverridevirtualnoexcept

Removes all points from the linestring.

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

◆ clone()

Cartesian_linestring * gis::Cartesian_linestring::clone ( ) const

inlineoverridevirtual

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.

inlineoverridevirtual

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

◆ front() [2/2]

Cartesian_point & gis::Cartesian_linestring::front ( )

inlineoverridevirtual

Returns the first point of the linestring.

Returns: First point of linestring

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

◆ operator[]() [1/2]

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

inlineoverridevirtual

Removes a point from the front of the linestring.

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 )

overridevirtual

Implements gis::Linestring.

Reimplemented in gis::Cartesian_linearring.

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.
