d1aa03a09b Better clip for very separate features 2016-08-03 13:41:22 +10:00

71ebdb8f69 [FEATURE] Optimise processing clip algorithm 
Before the algorithm was written to optimise clipping a few
features against thousands of mask features. The revised algorithm
is optimised for clipping thousands of input features against
a few mask features.

Given that this second operation is much more likely, it makes
sense to optimise for this use case.

I've also applied some other optimisations like taking advantage
of spatial indexes on the providers, using prepared geometries
and also only applying an intersection operation if the geometry
isn't wholly contained by the mask geometry.

Benchmarks:

clipping roads layer with 1 million lines against 2 polygons

before: 5 mins 30 seconds
after: 10 seconds

clipping address layer with 5 million points against 2 polygons

before: 50 minutes
after: 30 seconds

30fcaed634 [FEATURE][processing] New algorithm for merging connected lines 
This algorithm joins all connected parts of MultiLineString
geometries into single LineString geometries.

If any parts of the input MultiLineString geometries are not
connected, the resultant geometry will be a MultiLineString
containing any lines which could be merged and any non-connected
line parts.

bd7d913379 Refine QgsFeature geometry getters/setters 
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
