dispatchException
dispatchException: function( exception )
If the optional onException function is set, execute it and then dispatch the call to any other listener registered for onException.
If no optional onException function is set, we suspect that the user may have also not used OpenLayers.Ajax.Responders.register to register a listener for the onException call. To make sure that something gets done with this exception, only dispatch the call if there are listeners.
If you explicitly want to swallow exceptions, set request.options.onException to an empty function (function(){}) or register an empty function with OpenLayers.Ajax.Responders for onException.

Inherits from
| Properties | |
| unsupportedBrowsers | {Array} Array with browsers, which should use the HTTP-GET protocol instead of HTTP-POST for fetching tiles from a WMS . |

| usePost | {Boolean} |
| Constructor | |
| OpenLayers. | Creates a new WMS layer object. |
| Functions | |
| addTile | addTile creates a tile, initializes it and adds it as iframe to the layer div. |
unsupportedBrowsers
{Array} Array with browsers, which should use the HTTP-GET protocol instead of HTTP-POST for fetching tiles from a WMS . Defaults to [“mozilla”, “firefox”, “opera”], because Opera is not able to show transparent images in IFrames and Firefox/Mozilla has some ugly effects of viewport-shaking when panning the map. Both browsers, Opera and Firefox/Mozilla, have no problem with long urls, which is the reason for using POST instead of GET. The strings to pass to this array are the ones returned by <OpenLayers.BROWSER_NAME>.
OpenLayers.Layer.WMS.Post
Creates a new WMS layer object.
Example
var wms = new OpenLayers.Layer.WMS.Post(
"NASA Global Mosaic",
"http://wms.jpl.nasa.gov/wms.cgi",
{layers: "modis, global_mosaic"});Parameters
| name | {String} A name for the layer |
| url | {String} Base url for the WMS (e.g. http://wms.jpl.nasa.gov/wms.cgi) |
| params | {Object} An object with key/value pairs representing the GetMap query string parameters and parameter values. |
| options | {Object} Hashtable of extra options to tag onto the layer. |
addTile
addTile: function( bounds, position )
addTile creates a tile, initializes it and adds it as iframe to the layer div.
Parameters
| bounds | {OpenLayers.Bounds} |
| position | {OpenLayers.Pixel} |
Returns
{OpenLayers.Tile.Image.IFrame} The added OpenLayers.Tile.Image.IFrame

| moveTo | |
| addTileMonitoringHooks | This function takes a tile as input and adds the appropriate hooks to the tile so that the layer can keep track of the loading tile (making sure to check that the tile is always the layer’s current tile before taking any action). |
| removeTileMonitoringHooks | This function takes a tile as input and removes the tile hooks that were added in addTileMonitoringHooks() |

| setOpacity | Call the setOpacity method of the appropriate parent class to set the opacity. |
ratio
{Float} The ratio property determines the size of the serverside query relative to the map viewport size. By default, we load an area twice as big as the map, to allow for panning without immediately reload. Setting this to 1 will cause the area of the WFS request to match the map area exactly. It is recommended to set this to some number at least slightly larger than 1, otherwise accidental clicks can cause a data reload, by moving the map only 1 pixel.
featureClass
{OpenLayers.Feature} If featureClass is defined, an old-style markers based WFS layer is created instead of a new-style vector layer. If sent, this should be a subclass of OpenLayers.Feature
format
{OpenLayers.Format} The format you want the data to be parsed with. Must be passed in the constructor. Should be a class, not an instance. This option can only be used if no featureClass is passed / vectorMode is false: if a featureClass is passed, then this parameter is ignored.
formatObject
{OpenLayers.Format} Internally created/managed format object, used by the Tile to parse data.
