### Constants

### MIN_ZOOM_LEVEL

{Integer} 0

### MAX_ZOOM_LEVEL

{Integer} 15

### RESOLUTIONS

{Array(Float)} Hardcode these resolutions so that they are more closely tied with the standard wms projection

### Properties

### type

{YahooMapType}

### sphericalMercator

{Boolean} Should the map act as a mercator-projected map? This will cause all interactions with the map to be in the actual map projection, which allows support for vector drawing, overlaying other maps, etc.

### Constructor

### OpenLayers. Layer. Yahoo

#### Parameters

name | {String}
options | {Object}

### Functions

### loadMapObject

> loadMapObject:function()

Base class for 3rd party layers.
Some Layers will already have established zoom levels (like google or ve).
Instances of OpenLayers.Map are interactive maps embedded in a web page.
Instances of this class represent a width/height pair
