Detailed Description

Default geometry provider that works for Features with a DataType using a GeometryDataAnnotation.

It is implemented as follows: getGeometry: Calls Feature::findGeometry applyGeometry: Uses Feature::asBuilder to copy-and-edit a feature, and replaces the Geometry value of the property in the GeometryDataAnnotation by a new Geometry

This class should not be used when: The geometry of the feature is not exposed using Feature::findGeometry. The geometry isn't an explicit part of the feature, for example, but you can derive it from other properties on the feature. The returned geometry is not the same as the geometry exposed by Feature::findGeometry. It can be useful to display a distinct geometry when a user edits a feature. For example, when users edit the location and orientation of a vessel, you can show an Ellipse, which also has a location and an orientation. The feature has properties that are derived from the geometry. A simple example is a feature that has a Geometry property, and a property with the length of that geometry. When the Geometry property changes, the length property needs to change as well. You can do so by providing a custom implementation of IFeatureGeometryProvider::applyGeometry that changes the geometry, but also changes the length property.

In these cases, a custom IFeatureGeometryProvider implementation needs to be used. 2020.1

the original Feature

newGeometry

a new Geometry to apply on the Feature

a new Feature, based on a modified Geometry
