Deprecated. Instead of this layer, use OpenLayers.Layer.WMS with OpenLayers.Tile.Image.maxGetUrlLength configured in the layer’s <OpenLayers.Layer.WMS.tileOptions>.

#### Inherits from

- OpenLayers.Layer.WMS

Summary

Properties |
unsupportedBrowsers | {Array} Array with browsers, which should use the HTTP-GET protocol instead of HTTP-POST for fetching tiles from a WMS .
SUPPORTED_TRANSITIONS | {Array} no supported transitions for this type of layer, because it is not possible to modify the initialized tiles (iframes)

Constructor |
OpenLayers.Layer.WMS.Post | Creates a new WMS layer object.
Functions |

### Properties

### 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>.

### SUPPORTED_TRANSITIONS

{Array} no supported transitions for this type of layer, because it is not possible to modify the initialized tiles (iframes)

### usePost

{Boolean}

>      {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.

### Functions

### Properties

### isBaseLayer

{Boolean} WFS layer is not a base layer by default.

### tile

{OpenLayers.Tile.WFS}

### 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.

### DEFAULT_PARAMS

{Object} Hashtable of default key/value parameters

### 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.

### formatOptions

{Object} Hash of options which should be passed to the format when it is created. Must be passed in the constructor.

### vectorMode

{Boolean} Should be calculated automatically. Determines whether the layer is in vector mode or marker mode.

### encodeBBOX

{Boolean} Should the BBOX commas be encoded? The WMS spec says ‘no’, but some services want it that way. Default false.

### extractAttributes

{Boolean} Should the WFS layer parse attributes from the retrieved GML? Defaults to false. If enabled, parsing is slower, but attributes are available in the attributes property of layer features.

### Constructor

### OpenLayers.Layer.WFS

#### Parameters

name | {String}
url | {String}
params | {Object}
options | {Object} Hashtable of extra options to tag onto the layer

### addTileMonitoringHooks

> addTileMonitoringHooks: function( | tile | )

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).

#### Parameters

tile | {OpenLayers.Tile}

### removeTileMonitoringHooks

> removeTileMonitoringHooks: function( | tile | )

This function takes a tile as input and removes the tile hooks that were added in addTileMonitoringHooks()

#### Parameters

### onMapResize

> onMapResize: function()

Call the onMapResize method of the appropriate parent class.

#### Parameters

obj | {Object}

#### Returns

{OpenLayers.Layer.WFS} An exact clone of this OpenLayers.Layer.WFS

### getFullRequestString

> getFullRequestString:function( | newParams,
> | altUrl | )

combine the layer’s url with its params and these newParams.

Add the SRS parameter from ‘projection’ -- this is probably more eloquently done via a setProjection() method, but this works for now and always.

#### Parameters

newParams | {Object}
altUrl | {String} Use this as the url instead of the layer’s url

### commit

> commit: function()

Write out the data to a WFS server.

### commitSuccess

> commitSuccess: function( | request | )

Called when the Ajax request returns a response

#### Parameters

response | {XmlNode} from server

Called when the Ajax request fails

#### Parameters

response | {XmlNode} from server

### commitReport

> commitReport: function( | string,

string | {String} reporting string
response | {String} full XML response

### refresh
