Detailed Description

A layer for feature models.

Use FeatureLayer.NewBuilder to create a feature layer instance.

Member Function Documentation

◆ NewBuilder()

static Luciad.Layers.Features.FeatureLayer.Builder Luciad.Layers.Features.FeatureLayer.NewBuilder ( )

inlinestatic

Returns a new builder for creating a FeatureLayer.

Returns: a new builder for creating a FeatureLayer.

Property Documentation

◆ EditConfiguration

Luciad.Edit.Features.IFeatureEditConfiguration Luciad.Layers.Features.FeatureLayer.EditConfiguration

get

The edit configuration if editing is supported, or null.

[get]

Returns the edit configuration if editing is supported, or null. Whether or not the layer can be edited by the user is controlled using setEditable.

Since: 2020.1 [get]

See also: FeatureLayer.Builder.EditConfiguration

◆ EditCreateGeometryProvider

Luciad.Models.Features.IFeatureGeometryProvider Luciad.Layers.Features.FeatureLayer.EditCreateGeometryProvider

get

The edit/create geometry provider for a Feature.

[get]

Returns the edit/create geometry provider for a Feature.

Since: 2020.1 [get]

See also: FeatureLayer.Builder.EditCreateGeometryProvider

◆ IsEditable

bool Luciad.Layers.Features.FeatureLayer.IsEditable

getset

Whether this layer is editable.

[get]

Returns whether this layer is editable. A layer is editable if it has an IFeatureEditConfiguration and if the editable flag is set.

[set]

Sets whether this layer is editable. If the new value is different from the old one, a LayerEvent is delivered to the observers with the property name FeatureLayer.propertyEditable.

This flag is checked by the Editor when receiving events from the IFeatureEditCandidateProvider in conjunction with the model's IFeatureModelUpdater and the layer's IFeatureEditConfiguration.

This flag is true by default. This flag has no effect if the layer does not contain an IFeatureEditConfiguration or if the model's IFeatureModelUpdater is missing.

Since: 2020.1

See also: setEditable

◆ IsLabeled

bool Luciad.Layers.Features.FeatureLayer.IsLabeled

getset

Whether this layer displays labels.

[get]

Returns whether this layer displays labels.

[set]

Sets whether this layer displays labels. Note that in order for the layer to display labels, its IFeaturePainter should also call the FeatureCanvas.DrawLabel method for its features. If not, no labels will be displayed, regardless of this setting.

Since: 2020.2

◆ IsQueryable

bool Luciad.Layers.Features.FeatureLayer.IsQueryable

getset

Whether the features of this layer can be returned in the Map.QueryFeatures method.

[get]

Returns whether the features of this layer can be returned in the Map.QueryFeatures method.

[set]

Sets whether the features of this layer can be returned in the Map.QueryFeatures method. The default is true.

It is useful to set this property to false when:

you don't want features to be selected or set to the hovered state by the SelectEventHandler or HoverEventHandler classes.
there is a performance issue with the Map.QueryFeatures method, for example for a layer with many features that don't need to be selected.

Since: 2023.1

◆ LoadingStrategy

Luciad.Layers.Features.FeatureLayerLoadingStrategy Luciad.Layers.Features.FeatureLayer.LoadingStrategy

get

The loading strategy that is used.

[get]

Returns the loading strategy that is used.

Since: 2023.0.02 [get]

See also: FeatureLayer.Builder.LoadingStrategy

◆ Model

Luciad.Models.Features.IFeatureModel Luciad.Layers.Features.FeatureLayer.Model

get

The layer's model, which provides the features to present.

[get]

Returns the layer's model, which provides the features to present.

◆ Painter

Luciad.Layers.Features.IFeaturePainter Luciad.Layers.Features.FeatureLayer.Painter

getset

The layer's painter, which determines how the features are presented.

[get]

Returns the layer's painter, which determines how the features are presented.

[set]

Sets the layer's painter, which determines how the features are presented. It will replace the IFeaturePainter that was set using the FeatureLayer.Builder.Painter method, or if that method was not called, it will replace the default feature painter.

Limitation: This method currently only supports setting a new IFeaturePainter with the exact same level of details as the previous painter. If this is not the case, this method will throw an exception.

Exceptions

System.ArgumentNullException	when the given feature painter is `null`
System.ArgumentException	when the new painter has different detail levels than the previous painter

Since: 2023.1 [set]

◆ PropertyEditable

string Luciad.Layers.Features.FeatureLayer.PropertyEditable = PropertyEditableInternal()

staticget

Returns the property name for the LayerEvent that is fired as a result of changing the layer's editable flag.

Returns: the property name for the LayerEvent that is fired as a result of changing the layer's editable flag.

See also: setEditable

◆ PropertyLabeled

string Luciad.Layers.Features.FeatureLayer.PropertyLabeled = PropertyLabeledInternal()

staticget

Returns the property name for the LayerEvent that is fired as a result of changing the layer's labeled flag.

Returns: the property name for the LayerEvent that is fired as a result of changing the layer's labeled flag.

Since: 2020.2

See also: setLabeled

◆ PropertyPainter

string Luciad.Layers.Features.FeatureLayer.PropertyPainter = PropertyPainterInternal()

staticget

Returns the property name for the LayerEvent that is fired as a result of changing the layer's IFeaturePainter.

Returns: the property name for the LayerEvent that is fired as a result of changing the layer's IFeaturePainter.

Since: 2023.1

See also: Painter

◆ PropertyQueryable

string Luciad.Layers.Features.FeatureLayer.PropertyQueryable = PropertyQueryableInternal()

staticget

Returns the property name for the LayerEvent that is fired as a result of changing the layer's queryable flag.

Returns: the property name for the LayerEvent that is fired as a result of changing the layer's queryable flag.

Since: 2023.1

See also: setQueryable

◆ QueryConfiguration

Luciad.Layers.Features.FeatureQueryConfiguration Luciad.Layers.Features.FeatureLayer.QueryConfiguration

get

The query configuration, which specifies which feature to present at different map scales.

[get]

Returns the query configuration, which specifies which feature to present at different map scales.
