## Detailed Description

This reference to a node contains a node ID and a (possibly empty) location.

## Constructor & Destructor Documentation

## NodeRef()

osmium::NodeRef::NodeRef | ( | const osmium::object_id_type | ref = 0,
|  | const osmium::Location & | location = Location{} )

inlineconstexprnoexcept

Constructor for NodeRef

This is not explicit to allow implicit construction from an object ID.

## Member Function Documentation

## lat()

double osmium::NodeRef::lat | ( |  | ) | const

inline

Get latitude of the location in this NodeRef.

Exceptions

  osmium::invalid_location | if the location is not set.

## location() [1/2]

osmium::Location osmium::NodeRef::location | ( |  | ) | const

inlineconstexprnoexcept

Get location of this NodeRef.

## location() [2/2]

osmium::Location & osmium::NodeRef::location | ( |  | ) |

inlinenoexcept

Get reference to location in this NodeRef. Can be used to update it.

## lon()

double osmium::NodeRef::lon | ( |  | ) | const

inline

Get longitude of the location in this NodeRef.

Exceptions

  osmium::invalid_location | if the location is not set.

## positive_ref()

osmium::unsigned_object_id_type osmium::NodeRef::positive_ref | ( |  | ) | const

inlinenoexcept

Get absolute value of the reference ID of this NodeRef.

## ref()

osmium::object_id_type osmium::NodeRef::ref | ( |  | ) | const

inlineconstexprnoexcept

Get reference ID of this NodeRef.

## set_location()

NodeRef & osmium::NodeRef::set_location | ( | const osmium::Location & | location | ) |

inlinenoexcept

Set the location.

Returns
  Reference to this NodeRef for chaining calls.

## set_ref()

NodeRef & osmium::NodeRef::set_ref | ( | const osmium::object_id_type | ref | ) |

inlinenoexcept

Set the referenced ID.

Returns
  Reference to this NodeRef for chaining calls.

## x()

int32_t osmium::NodeRef::x | ( |  | ) | const

inlineconstexprnoexcept

Get internal x value of the location in this NodeRef.

## y()

int32_t osmium::NodeRef::y | ( |  | ) | const

inlineconstexprnoexcept

Get internal y value of the location in this NodeRef.
