ee720796a3 Change size()/count() == 0 and count() > 0 to isEmpty() checks 
Because:
- easier to read
- follows recommendations by clazy/KDAB
- potentially performance benefits

b7e1cae4f0 Switch double quoted single character to single quotes for some 
QString methods

Using single quotes is a significant performance boost. Rough
benchmarks indicate the QString single quote methods take
about 15% of the time the double quote variants take.

f628ebd423 Replace foreach with Q_FOREACH 
For:
- consistency
- to make it immediately clear that this is a Qt macro and that it
works slightly differently to c++ for loops

e832b2a28a Add QgsVectorLayer::fields() as alias to pendingFields() 
pendingFields() is not very intuitive and leads to confusion for new developers.

de48dad6e9 Followup #10912 - detect cycles in joins and reject joins that would create cycle 
Cycle would otherwise cause infinite loop when updating fields and it does not make sense

ffcd07b066 Joins: optionally use just a subset of fields from joined layer 2014-09-13 14:27:52 +07:00

071a5ec0c5 Fix #10912 (joined attributes are not correctly propagated in nested joins) 
This commit makes QgsVectorLayerJoinBuffer listen to changes in fields
of joined vector layers in order to update the cache and inform parent layer

81b0930498 QgsVectorLayer: large internal refactoring 
Most important changes:
- introduced feature iterator for QgsVectorLayer
- vector editing moved to QgsVectorEditBuffer
- complete rework of undo/redo commands for vector layers
- geometry cache separated from editing (QgsVectorLayerCache)
- non-essential editing functionality moved to QgsVectorLayerEditUtils
