5ea07684bd Also call invalidGeometryCallback when skipping features 2017-06-23 12:08:54 +10:00

482ed3f25a Explicitly mention in docs that presence of destination CRS does 
not affect filter expressions or virtual field values

a98923507e Allow specifying a destination CRS in QgsFeatureRequest 
If set, all geometries will be reprojected from their original
coordinate reference system to the destination CRS while
iterating over features.

If a CRS has been set as the destination CRS, then the filterRect
parameter should be specified in the same CRS as this destination
CRS.

Additionally, a callback function can be specified on the request
to be called if a transform exception is encountered while
iterating over features.

This is designed to make it easier for scripts and plugins to
correctly reproject layers in an efficient and robust way, instead
of having to implement lots of repeated code themselves and
potentially missing some of the important considerations which
come with reprojecting geometries & bounding boxes.

Now, if a script wants the features from a layer in a specific
CRS, they can call:

    crs = QgsCoordinateReferenceSystem('epsg:4326')
    request = QgsFeatureRequest().setDestinationCrs(crs)
    for f in layer.getFeatures(reqeuest):
        print('geometry in 4326 is {}.format(f.geometry().exportToWkt()))

f3e1772bb9 Remove QgsFeatureRequest::FilterRect 
This enum value has not been in use since filter rects were
separated from other filter types. Leaving it in API is confusing
and leads to incorrect use.

edb16d0014 [FEATURE] Feature limit support for feature requests 
Limits the maximum number of features returned by the iterator.
Some providers (postgres, spatialite, MS SQL) pass the limit on
to the provider to result in faster queries.

c49b5b777f Change a lot of arguments to const references in core/gui 
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!

e110855e6c [API] added QgsFeatureIterator, changed QgsVectorProvider API 
Vector data provider now has getFeatures() method to access features.
