public EditInteractiveOverlay()

Methods

OpenAsyncCore(IMapView, CancellationToken)

protected Task OpenAsyncCore(IMapView mapArguments, CancellationToken cancellationToken)

Parameters

mapArguments IMapView

cancellationToken CancellationToken

Remarks:

This method draws the representation of the overlay based on the extent you provided.

When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties that allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.

This method is the concrete wrapper for the abstract method RemoveVertexCore.

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

RemoveVertexCore(Feature, Vertex, Double)

This is the Core method of RemoveVertex which encapsulate the logic.

protected Feature RemoveVertexCore(Feature editShapeFeature, Vertex selectedVertex, double searchingTolerance)

Parameters

editShapeFeature Feature
This parameter specifies the target feature to be remove vertex from.

selectedVertex Vertex
This parameter specifies the selected vertex to search the vertex.

Returns

Feature
Returns a vertex removed feature.

Exceptions

ArgumentNullException
If you pass a null as the targetPointShape, we will throw an ArgumentNullException.

ArgumentOutOfRangeException
If you pass a searchingTolerance negative value, we will throw an ArgumentOutOfRangeException.
