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.

boundingBox()

BoundingBox Element::boundingBox

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 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.

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

inline

Definition at line 39 of file element.h.

tagsBegin()

std::vector< Tag >::const_iterator OSM::Element::tagsBegin

Definition at line 119 of file element.cpp.

tagsEnd()

std::vector< Tag >::const_iterator OSM::Element::tagsEnd

const

Definition at line 80 of file element.cpp.

tagValue() [2/5]

QByteArray Element::tagValue	(	const OSM::Languages &	languages,

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.
