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 438 of file qgsabstractgeometry.cpp.

Member Function Documentation

operator!=()

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

inline

Definition at line 1016 of file qgsabstractgeometry.h.

operator*()

QgsPoint QgsAbstractGeometry::vertex_iterator::operator*

(

)

const

Returns the current item.

Definition at line 476 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 448 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 469 of file qgsabstractgeometry.cpp.

operator==()

bool QgsAbstractGeometry::vertex_iterator::operator==

(

const vertex_iterator &

other

)

const

Definition at line 518 of file qgsabstractgeometry.cpp.

vertexId()

QgsVertexId QgsAbstractGeometry::vertex_iterator::vertexId

(

)

const

Returns vertex ID of the current item.
