OpenLayers.Tile - OpenLayers OpenLayers.TileThis is a class designed to designate a single tile, however it is explicitly designed to do relatively little.  Tiles store information about themselves -- such as the URL that they are related to, and their size - but do not add themselves to the layer div automatically, for example.  Create a new tile with the OpenLayers.Tile constructor, or a subclass.TBD 3.0remove reference to url in above paragraphSummaryOpenLayers.TileThis is a class designed to designate a single tile, however it is explicitly designed to do relatively little.

Properties events{OpenLayers.Events} An events object that handles all events on the tile.Register a listener for a particular event with the following syntaxtile.events.register(type, obj, listener);Supported event typesbeforedrawTriggered before the tile is drawn.  Used to defer drawing to an animation queue.  To defer drawing, listeners need to return false, which will abort drawing.  The queue handler needs to call <draw>(true) to actually draw the tile.loadstartTriggered when tile loading starts.loadendTriggered when tile loading ends.loaderrorTriggered before the loadend event (i.e. when the tile is still hidden) if the tile could not be loaded.reloadTriggered when an already loading tile is reloaded.unloadTriggered before a tile is unloaded. eventListeners{Object} If set as an option at construction, the eventListeners object will be registered with OpenLayers.Events.on.  Object structure must be a listeners object as shown in the example for the events.on method.This options can be set in the ``tileOptions`` option from OpenLayers.Layer.Grid.  For example, to be notified of the ``loadend`` event of each tiles:new OpenLayers.Layer.OSM('osm', 'http://tile.openstreetmap.org/${z}/${x}/${y}.png', { tileOptions: { eventListeners: { 'loadend': function(evt) { // do something on loadend } } } }); id{String} null layer{OpenLayers.Layer} layer the tile is attached to url{String} url of the request.TBD 3.0 Deprecated.  The base tile class does not need an url.  This should be handled in subclasses.  Does not belong here. bounds{OpenLayers.Bounds} null size{OpenLayers.Size} null position{OpenLayers.Pixel} Top Left pixel of the tile isLoading{Boolean} Is the tile loading?
