IFeatureLayer Interface

Provides access to members that control common aspects of a feature layer. Note: the IFeatureLayer interface has been superseded by IFeatureLayer2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Provides access to the properties and methods of a layer based on vector geographic data, which is typically a geodatabase, shapefile, or coverage feature class.

Members

Description
Read-only property AreaOfInterest The default area of interest for the layer.
Read/write property Cached Indicates if the layer needs its own display cache.
Read/write property DataSourceType Data source type.
Read/write property DisplayField Primary display field.
Method Draw Draws the layer to the specified display for the given draw phase.
Read/write property FeatureClass The layer's feature class.
Read/write property MaximumScale Maximum scale (representative fraction) at which the layer will display.
Read/write property MinimumScale Minimum scale (representative fraction) at which the layer will display.
Read/write property Name Layer name.
Read/write property ScaleSymbols Indicates if symbols are scaled for the layer.
Method Search Creates a cursor based upon the search criteria.
Read/write property Selectable Indicates if layer is selectable.
Read/write property ShowTips Indicates if the layer shows map tips.
Write-only property SpatialReference Spatial reference for the layer.
Read-only property SupportedDrawPhases Supported draw phases.
Read-only property TipText Map tip text at the specified location.
Read-only property Valid Indicates if the layer is currently valid.
Read/write property Visible Indicates if the layer is currently visible.

Inherited Interfaces

Interfaces Description

MAReferencedRpfLayer (esriDefenseSolutions) MAReferencedRpfLayer Class
TemporalFeatureLayer (esriTrackingAnalyst) Defines the coclass IDL parameters and attributes of the TemporalFeatureLayer COM object.

Remarks

This interface has properties that specify the feature class of the layer, the data source type, the primary display field, whether or not layer symbols scale based on the map's reference scale, and whether or not the layer is selectable.

There is also a method Search for performing a search on the layer. This method returns a cursor of features from the layer that meet a given search criteria. If there is a definition query set on the layer, Search will work on the subset of the features in the layer that meet the definition criteria. However, the Search method will not work on joined fields. If the feature layer has any joins, use the IGeoFeatureLayer::SearchDisplayFeatures method instead.

IGeoFeatureLayer provides access to all properties and methods of IFeatureLayer plus additional properties to access a layer's feature renderer and labeling properties. Fewer layer types support IGeoFeatureLayer compared to IFeatureLayer.
