Layer
A base class for all layers. Layer is the base class for all layer types. A layer is a representation of geographic data portrayed using symbols and text labels. Multiple layers can be 'stacked' to enhance the information displayed. Layers are displayed in an ArcGISMap inside a MapView control. Layers are drawn bottom-to-top, so the first layer in a map's layer collection is drawn first (on the bottom) and each subsequent layer is drawn on top of it.

Types
Functions
Cancels loading metadata for the Loadable object.
Fetches the list of legend info.
Returns the layer content's effective visibility at the specified scale. Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.
Properties
The unique identifying string for the layer, for example specified in a map or scene. The id is used by other parts of this API to refer to a specific Layer, such as in a set of FeatureFenceParameters or a FacilityLayerDefinition. If not supplied, all layers will be assigned a unique id when created.
