Interface IFeatureGeometryProvider

All Known Implementing Classes:

DefaultFeatureGeometryProvider

public interface IFeatureGeometryProvider

This class can provide the Geometry associated with a Feature, and apply Geometry changes on that Feature.

this can for example be used to specify the Geometry that is used to edit or create a Feature.

See the related guide for an overview of the editing API.

See DefaultFeatureGeometryProvider for a default implementation that works for Features that use GeometryDataAnnotation.

The provided geometry is not necessarily the same geometry as the one used for painting. An example would be to modify the location and orientation of a vessel by editing it as an Ellipse, which also has a location and an orientation. This could be implemented by:

• having getGeometry return an Ellipse geometry based on the location and orientation stored in a Feature
• having applyGeometry map the new Ellipse geometry back to a location and an orientation, and modify the Feature accordingly.

Similarly, a vessel feature could be created by creating an Ellipse geometry.

Method Summary

Modifier and Type	Method	Description
Feature	applyGeometry(Feature originalFeature, Geometry newGeometry)	Updates the original Feature using the modified Geometry, and returns it.
Geometry	getGeometry(Feature feature)	Return the geometry for a Feature (for example a Geometry using which a Geometry can be edited or created).

Method Details

getGeometry

@Nullable
Geometry getGeometry(@NotNull
 Feature feature)

Return the geometry for a Feature (for example a Geometry using which a Geometry can be edited or created).

This Geometry is not necessarily the same geometry as the one used for painting.

See IFeatureGeometryProvider for more information.

Parameters:

feature - the Feature to edit

Returns:

the Geometry using which a Feature can be edited, or null if the Feature can not be edited using a Geometry

applyGeometry

@Nullable
Feature applyGeometry(@NotNull
 Feature originalFeature,
 @NotNull
 Geometry newGeometry)

Updates the original Feature using the modified Geometry, and returns it.

This Geometry is not necessarily the same geometry as the one used for painting. See IFeatureGeometryProvider for an example.

Parameters:

originalFeature - the original Feature

newGeometry - a new Geometry to apply on the Feature

Returns:

a new Feature, based on a modified Geometry
