Constructor & Destructor Documentation
◆ QgsVectorDataProviderFeaturePool()
| QgsVectorDataProviderFeaturePool::QgsVectorDataProviderFeaturePool | ( | QgsVectorLayer * | layer, |
| bool | selectedOnly = false |
||
| ) |
Creates a new feature pool for the data provider of layer.
If selectedOnly is set to true, only selected features will be managed by the pool.
