All pointer based methods have been removed.
Now we have only:
void setGeometry( const QgsGeometry& geom )
and
QgsGeometry geometry() const
Benefits include avoiding a whole lot of tricky pointer lifetime
issues, potential memory leaks, and finally closing #777, which
has survived for over 9 years!...
Impacts on PyQGIS code:
- no more need for the messy
g = QgsGeometry( feature.geometry() )
workaround, just use g = feature.geometry() instead
- IMPORTANT: you can no longer test whether a feature has geometry
using `if f.geometry():`, since QgsFeature::geometry() will
*always* return an object. Instead, use
`if not f.geometry().isEmpty():`, or preferably the new method
`if not f.hasGeometry():`
Fix#777
- add selectByRect( QgsRectangle&, SelectBehaviour) and
selectByIds( QgsFeatureIds, SelectBehaviour) for selecting
by rect and ids respectively, with options to add to selection/
remove from selection/intersect with current selection
- deprecate select( QgsRectangle ) and setSelectedFeatures in
favour of new methods
- add unit tests
- use at() instead of [] for temporary containers (at() returns
const reference, so it avoids the detach which occurs with [])
- use at( 0 ) rather than first() for containers, because first()
detaches (Qt5 introduced constFirst()/constLast() to overcome this)
