Member Function Documentation

◆ accept()

bool gis::Geographic_multilinestring::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::Multilinestring.

◆ back() [1/2]

Geographic_linestring & gis::Geographic_multilinestring::back ( )

inline

◆ back() [2/2]

const Geographic_linestring & gis::Geographic_multilinestring::back ( ) const

inline

◆ begin() [1/2]

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

inlinenoexcept

◆ begin() [2/2]

iterator gis::Geographic_multilinestring::begin ( void )

inlinenoexcept

◆ clear()

void gis::Geographic_multilinestring::clear ( )

inlineoverridevirtualnoexcept

Removes all geometries from the geometrycollection.

Implements gis::Geometrycollection.

◆ clone()

Geographic_multilinestring * gis::Geographic_multilinestring::clone ( ) const

inlineoverridevirtual

Clone pattern to easily duplicate a Multilinestring.

Returns: A pointer to a copy of the Multilinestring that caller must free when it is done with it.

Implements gis::Multilinestring.

◆ coordinate_system()

Coordinate_system gis::Geographic_multilinestring::coordinate_system ( ) const

inlineoverridevirtual

Gets the coordinate system.

Returns: The coordinate system type.

Implements gis::Geometry.

◆ empty()

bool gis::Geographic_multilinestring::empty ( ) const

overridevirtual

Checks if the collection is empty.

Return values

true	The polygon is empty.
false	The polygon is not empty.

Implements gis::Geometrycollection.

◆ end() [1/2]

const_iterator gis::Geographic_multilinestring::end ( void ) const

inlinenoexcept

◆ end() [2/2]

iterator gis::Geographic_multilinestring::end ( void )

inlinenoexcept

◆ front() [1/2]

const Geographic_linestring & gis::Geographic_multilinestring::front ( ) const

inlineoverridevirtual

Implements gis::Multilinestring.

◆ front() [2/2]

Geographic_linestring & gis::Geographic_multilinestring::front ( )

inlineoverridevirtual

Returns the first linestring of the Multilinestring.

Returns: First linestring of the Multilinestring

Implements gis::Multilinestring.

◆ is_empty()

bool gis::Geographic_multilinestring::is_empty ( ) const

inlineoverridevirtual

Check if this is an empty geometry.

The definition of empty geometries is the one in SFA-CA (OGC 06-103r4, Sect. 6.1.2.2), i.e., an empty point set.

Note: This is different from the function "empty", which returns true if a geometry contains no subgeometries. E.g., a geometry collection may contain another geometry collection which is empty. In this case, the "empty" function would return false on the outermost geometry collection, while "is_empty" would return true.

Return values

true	The geometry represents the empty point set.
false	The geometry represent a non-empty point set.

Implements gis::Geometry.

◆ operator[]() [1/2]

const Geometry & gis::Geographic_multilinestring::operator[] ( std::size_t i ) const

inlineoverridevirtual

Implements gis::Geometrycollection.

◆ operator[]() [2/2]

Geographic_linestring & gis::Geographic_multilinestring::operator[] ( std::size_t i )

inlineoverridevirtual

Implements gis::Geometrycollection.

◆ pop_front()

void gis::Geographic_multilinestring::pop_front ( )

inlineoverridevirtual

Removes a geometry from the front of the collection.

Implements gis::Geometrycollection.

◆ push_back() [1/2]

void gis::Geographic_multilinestring::push_back ( const Geometry & g )

overridevirtual

Adds a geometry to the collection.

Parameters

g	The geometry to add.

Implements gis::Geometrycollection.

◆ push_back() [2/2]

void gis::Geographic_multilinestring::push_back ( Geometry && g )

overridevirtual

Implements gis::Geometrycollection.

◆ resize()

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

inlineoverridevirtual

Resizes the geometrycollection to contain a given number of elements.

If the new size is smaller than the current size, the remaining geometries are discarded.

Parameters

[in] count The new number of geometries.

Implements gis::Geometrycollection.

◆ size()

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

inlineoverridevirtual

Returns the size of the geometrycollection.

Returns: Number of geometries in the geometrycollection.

Implements gis::Geometrycollection.
