Class: QgsGml

class qgis.core.QgsGml

Bases: PyQt5.QtCore.QObject

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 *

Methods

childEvent
connectNotify
crs Returns features spatial reference system
customEvent
disconnectNotify
featuresMap Gets parsed features for given type name
getFeatures Read from GML data.
getFeaturesUri Does the Http GET request to the wfs server Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings.
idsMap Gets feature ids map
isSignalConnected
receivers
sender
senderSignalIndex
timerEvent

Signals

dataProgressAndSteps Also emit signal with progress and totalSteps together (this is better for the status message) [signal]
dataReadProgress dataReadProgress(self, int) [signal]
totalStepsUpdate totalStepsUpdate(self, int) [signal]

Attributes

Gets parsed features for given type name

getFeatures(self, data: Union[QByteArray, bytes, bytearray], extent: QgsRectangle = None) → Tuple[int, QgsWkbTypes.Type]

Read from GML data. Constructor uri param is ignored Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings.

getFeaturesUri(self, uri: str, extent: QgsRectangle = None, userName: str = '', password: str = '', authcfg: str = '') → Tuple[int, QgsWkbTypes.Type]

Does the Http GET request to the wfs server Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings.
