Detailed Description

Low-level types and functions to work with raw OSM data as efficiently as possible.

Typedef Documentation

Id

typedef int64_t OSM::Id

OSM element identifier.

Definition at line 27 of file datatypes.h.

Enumeration Type Documentation

Type

enum OSM::Type : uint8_t

strong

Element type.

Definition at line 258 of file datatypes.h.

Function Documentation

appendNodesFromWay()

template<typename Iter >

static void OSM::appendNodesFromWay ( const DataSet &  dataSet, std::vector< const Node * > &  nodes, const Iter &  nodeBegin, const Iter &  nodeEnd  )

static

Appends the nodes referenced by nodesBegin and @pnodesEnd into nodes.

This would typically be iterators on OSM::Way::nodes.

Definition at line 24 of file pathutil.h.

assemblePath()

void OSM::assemblePath	(	const DataSet &	dataSet,
		std::vector< const Way * > &&	ways,
		std::vector< const Node * > &	path
	)

Assemble a continuous path into path from the given ways.

Definition at line 42 of file pathutil.cpp.

coalesce()

constexpr Element OSM::coalesce ( Element  e )

constexpr

Utility function similar to SQL COALESCE for OSM::Element, ie.

this returns the first non-null element passed as argument.

Definition at line 138 of file element.h.

copy_element()

UniqueElement OSM::copy_element

(

Element

e

)

Creates a copy of element.

Definition at line 300 of file element.cpp.

degToRad()

constexpr double OSM::degToRad ( double  deg )

inlineconstexpr

Degree to radian conversion.

Definition at line 19 of file geomath.h.

distance() [1/4]

double OSM::distance	(	const std::vector< const OSM::Node * > &	path,
		OSM::Coordinate	coord
	)

Distance between the given polygon and coordinate, in meter.

Definition at line 47 of file geomath.cpp.

distance() [2/4]

double OSM::distance	(	Coordinate	coord1,
		Coordinate	coord2
	)

Distance between coord1 and coord2 in meter.

Definition at line 27 of file geomath.cpp.

distance() [3/4]

double OSM::distance	(	OSM::Coordinate	l1,
		OSM::Coordinate	l2,
		OSM::Coordinate	p
	)

Distance in meters between a line segment defined by l1 and l2 to a point p.

Definition at line 32 of file geomath.cpp.

distance() [4/4]

double OSM::distance	(	double	lat1,
		double	lon1,
		double	lat2,
		double	lon2
	)

Distance between two coordinates.

Definition at line 16 of file geomath.cpp.

radToDeg()

constexpr double OSM::radToDeg ( double  rad )

inlineconstexpr

Radian to degree conversion.

Definition at line 24 of file geomath.h.

removeTag()

template<typename Elem >

void OSM::removeTag ( Elem &  elem, TagKey  key  )

inline

Removes a tag from the given element.

Definition at line 501 of file datatypes.h.

setTag()

template<typename Elem >

void OSM::setTag ( Elem &  elem, Tag &&  tag  )

inline

Inserts a new tag, or replaces an existing one with the same key.

Definition at line 481 of file datatypes.h.

setTagValue()

template<typename Elem >

void OSM::setTagValue ( Elem &  elem, TagKey  key, const QByteArray &  value  )

inline

Inserts a new tag, or updates an existing one.

Definition at line 493 of file datatypes.h.

tagValue() [1/3]

template<typename Elem >

QByteArray OSM::tagValue ( const Elem &  elem, const char *  keyName  )

inline

Returns the tag value for key name keyName of elem.

Warning

This is slow due to doing a linear search and string comparissons. Where possible avoid this in favor of tagValue().

Definition at line 420 of file datatypes.h.

tagValue() [2/3]

template<typename Elem >

QByteArray OSM::tagValue ( const Elem &  elem, const QLocale &  locale, const char *  keyName  )

inline

Returns the localized version of the tag value for key name keyName of elem.

Warning

This is slow due to doing a linear search and string comparissons.

Definition at line 433 of file datatypes.h.

tagValue() [3/3]

template<typename Elem >

QByteArray OSM::tagValue ( const Elem &  elem, TagKey  key  )

inline

Returns the tag value for key of elem.

Definition at line 406 of file datatypes.h.

ztileFromBoundingBox()

ZTile OSM::ztileFromBoundingBox

(

OSM::BoundingBox

bbox

)

The smallest tile entirely containing the given bounding box.

Definition at line 49 of file ztile.cpp.
