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 318 of file qgsabstractgeometry.cpp.

Member Function Documentation

◆ operator!=()

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

inline

Definition at line 918 of file qgsabstractgeometry.h.

◆ operator*()

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

Returns the current item.

Definition at line 356 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 328 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 349 of file qgsabstractgeometry.cpp.

◆ operator==()

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

Definition at line 398 of file qgsabstractgeometry.cpp.

◆ vertexId()

QgsVertexId QgsAbstractGeometry::vertex_iterator::vertexId ( ) const

Returns vertex ID of the current item.

Definition at line 362 of file qgsabstractgeometry.cpp.
