Detailed Description

The part_iterator class provides an STL-style iterator for const references to geometry parts.

Since: QGIS 3.6

Constructor & Destructor Documentation

◆ const_part_iterator() [1/2]

QgsAbstractGeometry::const_part_iterator::const_part_iterator ( )

default

Create invalid iterator.

◆ const_part_iterator() [2/2]

QgsAbstractGeometry::const_part_iterator::const_part_iterator	(	const QgsAbstractGeometry *	g,
		int	index )

Create part iterator for a geometry.

Definition at line 613 of file qgsabstractgeometry.cpp.

Member Function Documentation

◆ operator!=()

bool QgsAbstractGeometry::const_part_iterator::operator!= ( const_part_iterator other ) const

inline

Definition at line 946 of file qgsabstractgeometry.h.

◆ operator*()

const QgsAbstractGeometry * QgsAbstractGeometry::const_part_iterator::operator* ( ) const

Returns the current item.

Definition at line 642 of file qgsabstractgeometry.cpp.

◆ operator++() [1/2]

QgsAbstractGeometry::const_part_iterator & QgsAbstractGeometry::const_part_iterator::operator++ ( )

The prefix ++ operator (++it) advances the iterator to the next part and returns an iterator to the new current part.

Calling this function on iterator that is already past the last item leads to undefined results.

Definition at line 619 of file qgsabstractgeometry.cpp.

◆ operator++() [2/2]

QgsAbstractGeometry::const_part_iterator QgsAbstractGeometry::const_part_iterator::operator++ ( int )

The postfix ++ operator (it++) advances the iterator to the next part and returns an iterator to the previously current part.

Definition at line 635 of file qgsabstractgeometry.cpp.

◆ operator==()

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

Definition at line 658 of file qgsabstractgeometry.cpp.

◆ partNumber()

int QgsAbstractGeometry::const_part_iterator::partNumber ( ) const

Returns the part number of the current item.

Definition at line 653 of file qgsabstractgeometry.cpp.
