Public Member Functions | |
vertex_iterator ()=default | |
Create invalid iterator. | |
vertex_iterator (const QgsAbstractGeometry *g, int index) | |
Create vertex iterator for a geometry. | |
bool | operator!= (const vertex_iterator &other) const |
QgsPoint | operator* () const |
Returns the current item. | |
vertex_iterator & | operator++ () |
The prefix ++ operator (++it) advances the iterator to the next vertex and returns an iterator to the new current vertex. | |
vertex_iterator | operator++ (int) |
The postfix ++ operator (it++) advances the iterator to the next vertex and returns an iterator to the previously current vertex. | |
bool | operator== (const vertex_iterator &other) const |
QgsVertexId | vertexId () const |
Returns vertex ID of the current item. | |

QgsPoint QgsAbstractGeometry::vertex_iterator::operator* | ( | ) | const |
Returns the current item.
Definition at line 482 of file qgsabstractgeometry.cpp.
QgsAbstractGeometry::vertex_iterator & QgsAbstractGeometry::vertex_iterator::operator++ | ( | ) |
The prefix ++ operator (++it) advances the iterator to the next vertex and returns an iterator to the new current vertex.
Calling this function on iterator that is already past the last item leads to undefined results.

QgsAbstractGeometry::vertex_iterator QgsAbstractGeometry::vertex_iterator::operator++ | ( | int | ) |
The postfix ++ operator (it++) advances the iterator to the next vertex and returns an iterator to the previously current vertex.

bool QgsAbstractGeometry::vertex_iterator::operator== | ( | const vertex_iterator & | other | ) | const |
Definition at line 524 of file qgsabstractgeometry.cpp.
QgsVertexId QgsAbstractGeometry::vertex_iterator::vertexId | ( | ) | const |
Returns vertex ID of the current item.
