Provides access to members that work with all layers. Note: the ILayer interface has been superseded byILayer2. Please consider using the more recent version.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
ILayer is a generic interface for all layer objects. This interface has a method to draw the layer and provides access to generic layer properties.

Remarks
This
interface has a method to draw the layer and properties to define
the minimum and maximum display scales, the spatial reference, the
name, layer visibility, whether or not the layer is cached, and
whether or not the layer shows map tips.
There are
also properties that indicate whether the layer is valid, its
supported draw phases, area of interest, and the map tip text for a
given coordinate.
