IFeatureLayer Interface

Provides access to members that control common aspects of a feature layer. Note: the IFeatureLayer interface has been superseded byIFeatureLayer2. 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

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

Inherited Interfaces

CoClasses that implement IFeatureLayer

CoClasses and Classes	Description
CadAnnotationLayer	An Esri Cad annotation layer.
CadastralFabricSubLayer	Cadastral Fabric Feature Layer Object.
CadFeatureLayer	Esri CAD Feature Layer class.
CoverageAnnotationLayer	An Esri coverage annotation layer.
DimensionLayer	A collection of properties for a dimension layer.
FDOGraphicsLayer	A collection of properties for an annotation layer (feature data object graphics layer).
FeatureLayer	A collection of features and their visual representation.
GdbRasterCatalogLayer	Geodabase RasterCatalog source and display options.
ImageServerLayer	Image server layer source and display options.
IMSSubFeatureLayer	A collection of IMS features as a sublayer of an IMSMapLayer.
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.
