Constructor & Destructor Documentation

◆ vertex_iterator() [1/2]

QgsAbstractGeometry::vertex_iterator::vertex_iterator ( )
default

Create invalid iterator.

◆ vertex_iterator() [2/2]

QgsAbstractGeometry::vertex_iterator::vertex_iterator ( const QgsAbstractGeometry g,
int  index 
)

Create vertex iterator for a geometry.

Definition at line 307 of file qgsabstractgeometry.cpp.

Member Function Documentation

◆ operator!=()

bool QgsAbstractGeometry::vertex_iterator::operator!= ( const vertex_iterator other) const
inline

Definition at line 787 of file qgsabstractgeometry.h.

◆ operator*()

QgsPoint QgsAbstractGeometry::vertex_iterator::operator* ( ) const

Returns the current item.

Definition at line 345 of file qgsabstractgeometry.cpp.

◆ operator++() [1/2]

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.

Definition at line 317 of file qgsabstractgeometry.cpp.

◆ operator++() [2/2]

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.

Definition at line 338 of file qgsabstractgeometry.cpp.

◆ operator==()

bool QgsAbstractGeometry::vertex_iterator::operator== ( const vertex_iterator other) const

Definition at line 387 of file qgsabstractgeometry.cpp.

◆ vertexId()

QgsVertexId QgsAbstractGeometry::vertex_iterator::vertexId ( ) const

Returns vertex ID of the current item.

Definition at line 351 of file qgsabstractgeometry.cpp.
