Detailed Description

A reference to any of OSM::Node/OSM::Way/OSM::Relation.

Lifetime of the referenced object needs to extend beyond the lifetime of this.

Member Function Documentation

◆ boundingBox()

BoundingBox Element::boundingBox ( ) const

Definition at line 46 of file element.cpp.

◆ center()

Coordinate Element::center ( ) const

Definition at line 29 of file element.cpp.

◆ hasTag()

bool Element::hasTag ( TagKey key) const

Returns true if this element has a tag with key key.

Definition at line 114 of file element.cpp.

◆ hasTags()

bool OSM::Element::hasTags ( ) const
inline

Returns whether or not this element has any tags set.

Definition at line 53 of file element.h.

◆ id()

Id Element::id ( ) const

Definition at line 12 of file element.cpp.

◆ node()

const Node * OSM::Element::node ( ) const
inline

Definition at line 37 of file element.h.

◆ operator bool()

Definition at line 34 of file element.h.

◆ operator!=()

bool OSM::Element::operator!= ( Element other) const
inline

Definition at line 32 of file element.h.

◆ operator<()

bool OSM::Element::operator< ( Element other) const
inline

Definition at line 33 of file element.h.

◆ operator==()

bool OSM::Element::operator== ( Element other) const
inline

Definition at line 31 of file element.h.

◆ outerPath()

std::vector< const Node * > Element::outerPath ( const DataSet & dataSet) const

Returns all nodes belonging to the outer path of this element.

In the simplest case that's a single closed polygon, but it can also be a sequence of multiple closed loop polygons, or a polyline.

Definition at line 166 of file element.cpp.

◆ recomputeBoundingBox()

void Element::recomputeBoundingBox ( const DataSet & dataSet)

Recompute the bounding box of this element.

We usually assume those to be provided by Overpass/osmconvert, but there seem to be cases where those aren't reliable.

Definition at line 207 of file element.cpp.

◆ relation()

const Relation * OSM::Element::relation ( ) const
inline

Definition at line 39 of file element.h.

◆ tagsBegin()

std::vector< Tag >::const_iterator OSM::Element::tagsBegin ( ) const

Definition at line 119 of file element.cpp.

◆ tagsEnd()

std::vector< Tag >::const_iterator OSM::Element::tagsEnd ( ) const

Definition at line 134 of file element.cpp.

◆ tagValue() [1/5]

QByteArray Element::tagValue ( const char * keyName) const

Definition at line 80 of file element.cpp.

◆ tagValue() [2/5]

QByteArray Element::tagValue ( const OSM::Languages & languages,
const char * keyName ) const

Definition at line 97 of file element.cpp.

◆ tagValue() [3/5]

template<typename K , typename ... Args>
QByteArray OSM::Element::tagValue ( const OSM::Languages & languages,
K key,
Args... args ) const

Definition at line 88 of file element.h.

◆ tagValue() [4/5]

template<typename K , typename ... Args>
QByteArray OSM::Element::tagValue ( K key,
Args... args ) const

Returns the value of the first non-empty tag.

Both OSM::TagKey (fast) and const char* (slow) keys are accepted.

Definition at line 78 of file element.h.

◆ tagValue() [5/5]

QByteArray Element::tagValue ( TagKey key) const

Definition at line 63 of file element.cpp.
