Detailed Description

A colletion of linestrings.

Multilinestring is an instantiable type in SQL.

Member Function Documentation

◆ accept()

bool gis::Multilinestring::accept ( Geometry_visitor v)
overridepure virtual

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::Multicurve.

Implemented in gis::Geographic_multilinestring, and gis::Cartesian_multilinestring.

◆ clone()

Multilinestring* gis::Multilinestring::clone ( ) const
overridepure virtual

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::Geometrycollection.

Implemented in gis::Geographic_multilinestring, and gis::Cartesian_multilinestring.

◆ create_multilinestring()

Multilinestring * gis::Multilinestring::create_multilinestring ( Coordinate_system  coordinate_system)
static

Creates a subclass of Multilinestring from a Coordinate_system.

Parameters
[in]coordinate_systemCoordinate system to create a Multilinestring for.
Returns
A pointer to a Multilinestring that caller must free when it is done with it.

◆ front() [1/2]

const Linestring& gis::Multilinestring::front ( ) const
overridepure virtual

◆ front() [2/2]

Linestring& gis::Multilinestring::front ( )
overridepure virtual

Returns the first linestring of the Multilinestring.

Returns
First linestring of the Multilinestring

Implements gis::Geometrycollection.

Implemented in gis::Geographic_multilinestring, and gis::Cartesian_multilinestring.

◆ type()

Geometry_type gis::Multilinestring::type ( ) const
inlineoverridevirtual

Gets the geometry type of the object.

Returns
The type of this object

Implements gis::Multicurve.
