Typedef Documentation

◆ QgsMultiPointXY

typedef QVector<QgsPointXY> QgsMultiPointXY

A collection of QgsPoints that share a common collection of attributes.

Definition at line 81 of file qgsgeometry.h.

◆ QgsMultiPolygonXY

typedef QVector<QgsPolygonXY> QgsMultiPolygonXY

A collection of QgsPolygons that share a common collection of attributes.

Definition at line 92 of file qgsgeometry.h.

◆ QgsMultiPolylineXY

A collection of QgsPolylines that share a common collection of attributes.

Definition at line 85 of file qgsgeometry.h.

◆ QgsPolygonXY

typedef QVector<QgsPolylineXY> QgsPolygonXY

Polygon: first item of the list is outer ring, inner rings (if any) start from second item.

Definition at line 75 of file qgsgeometry.h.

◆ QgsPolyline

Polyline as represented as a vector of points.

This type has full support for Z/M dimensions.

Since
QGIS 3.0

Definition at line 71 of file qgsgeometry.h.

◆ QgsPolylineXY

typedef QVector<QgsPointXY> QgsPolylineXY

Polyline as represented as a vector of two-dimensional points.

This type has no support for Z/M dimensions and use of QgsPolyline is encouraged instead.

Note
In QGIS 2.x this type was available as QgsPolyline.
Since
QGIS 3.0

Definition at line 62 of file qgsgeometry.h.

Function Documentation

◆ operator<<()

CORE_EXPORT QDataStream& operator<< ( QDataStream &  out,
const QgsGeometry geometry 
)

Writes the geometry to stream out. QGIS version compatibility is not guaranteed.

Definition at line 3815 of file qgsgeometry.cpp.

◆ operator>>()

CORE_EXPORT QDataStream& operator>> ( QDataStream &  in,
QgsGeometry geometry 
)

Reads a geometry from stream in into geometry. QGIS version compatibility is not guaranteed.

Definition at line 3821 of file qgsgeometry.cpp.
