Constructor & Destructor Documentation

part_iterator() [1/2]

QgsAbstractGeometry::part_iterator::part_iterator ( )

default

Create invalid iterator.

part_iterator() [2/2]

QgsAbstractGeometry::part_iterator::part_iterator	(	QgsAbstractGeometry *	g,
		int	index
	)

Create part iterator for a geometry.

Member Function Documentation

operator!=()

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

inline

Definition at line 869 of file qgsabstractgeometry.h.

operator*()

QgsAbstractGeometry * QgsAbstractGeometry::part_iterator::operator*

(

)

const

Returns the current item.

Definition at line 580 of file qgsabstractgeometry.cpp.

operator++() [1/2]

QgsAbstractGeometry::part_iterator & QgsAbstractGeometry::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 557 of file qgsabstractgeometry.cpp.

operator++() [2/2]

QgsAbstractGeometry::part_iterator QgsAbstractGeometry::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 573 of file qgsabstractgeometry.cpp.

operator==()

bool QgsAbstractGeometry::part_iterator::operator==

(

QgsAbstractGeometry::part_iterator

other

)

const

Definition at line 596 of file qgsabstractgeometry.cpp.

partNumber()

int QgsAbstractGeometry::part_iterator::partNumber

(

)

const

Returns the part number of the current item.
