ILayer2 Interface

Provides access to additional members that work with all layers.

Product Availability

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

Description

ILayer2 is a generic interface for all layer objects. This interface has a method to draw the layer and provides access to generic layer properties. This interface adds to what is supported by ILayer by adding a property that indicates whether or not the scale range properties are read only and a property that lets you set the layer's area of interest.

	AreaOfInterest	The default area of interest for the layer.
	Cached	Indicates if the layer needs its own display cache.
	Draw	Draws the layer to the specified display for the given draw phase.
	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.
	ScaleRangeReadOnly	Indicates if the minimum and maximum scale range values are read-only.
	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.
