Signals | |
void | dataProgressAndSteps (int progress, int totalSteps) |
Also emit signal with progress and totalSteps together (this is better for the status message) More... | |

Does the Http GET request to the wfs server Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings. More... | |
int | getFeatures (const QByteArray &data, QgsWkbTypes::Type *wkbType, QgsRectangle *extent=nullptr) |
Read from GML data. More... | |
QMap< QgsFeatureId, QString > | idsMap () const |
Gets feature ids map. More... | |
This class reads data from a WFS server or alternatively from a GML file.
It uses the expat XML parser and an event based model to keep performance high. The parsing starts when the first data arrives, it does not wait until the request is finished
