Property Detail

altitude

property

altitude:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The altitude in meters.

If altitude is not supported by the device, then this property is set to NaN.

Implementation
public function get altitude():Number
public function set altitude(value:Number):void

heading

property

heading:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The direction of movement (with respect to true north) in integer degrees. This is not the same as "bearing", which returns the direction of movement with respect to another point.

Note: On Android devices, heading is not supported. The value of the heading property is always NaN (Not a Number).

Implementation
public function get heading():Number
public function set heading(value:Number):void

horizontalAccuracy

property

horizontalAccuracy:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The horizontal accuracy in meters.

Implementation
public function get horizontalAccuracy():Number
public function set horizontalAccuracy(value:Number):void

latitude

property

latitude:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The latitude in degrees. The latitude values have the following range: (-90 <= latitude <= 90). Negative latitude is south and positive latitude is north.

Implementation
public function get latitude():Number
public function set latitude(value:Number):void

longitude

property

longitude:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The longitude in degrees. The longitude values have the following range: (-180 <= longitude < 180). Negative longitude is west and positive longitude is east.

Implementation
public function get longitude():Number
public function set longitude(value:Number):void

speed

property

speed:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The speed in meters/second.

Implementation
public function get speed():Number
public function set speed(value:Number):void

timestamp

property

timestamp:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The number of milliseconds at the time of the event since the runtime was initialized. For example, if the device captures geolocation data 4 seconds after the application initializes, then the timestamp property of the event is set to 4000.

Implementation
public function get timestamp():Number
public function set timestamp(value:Number):void

verticalAccuracy

property

verticalAccuracy:Number

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

The vertical accuracy in meters.

Implementation
public function get verticalAccuracy():Number
public function set verticalAccuracy(value:Number):void

Constructor Detail

()

Constructor

public function GeolocationEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, latitude:Number = 0, longitude:Number = 0, altitude:Number = 0, hAccuracy:Number = 0, vAccuracy:Number = 0, speed:Number = 0, heading:Number = 0, timestamp:Number = 0)

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

Creates a GeolocationEvent object that contains information about the location of the device. Event objects are passed as parameters to event listeners.

Parameters

	`type:String` — Specifies the type of the event. Event listeners can access this information through the inherited `type` property. There is only one type of update event: `GeolocationEvent.UPDATE`.

	`bubbles:Boolean` (default = `false`) — Indicates whether the event is a bubbling event. Event listeners can access this information through the inherited `bubbles` property.

	`cancelable:Boolean` (default = `false`) — Determines whether the event object can be canceled. Event listeners can access this information through the inherited `cancelable` property.

	`latitude:Number` (default = `0`) — Returns the latitude in degrees. The values have the following range: (-90 <= Lat <= +90).

	`longitude:Number` (default = `0`) — Returns the longitude in degrees. The values have the following range: (-180 <= Long < +180).

	`altitude:Number` (default = `0`) — Returns the altitude in meters.

	`hAccuracy:Number` (default = `0`) — Returns the horizontal accuracy in meters.

	`vAccuracy:Number` (default = `0`) — Returns the vertical accuracy in meters.

	`speed:Number` (default = `0`) — Returns the speed in meters/second.

	`heading:Number` (default = `0`) — Returns the direction of movement (with respect to True North) in integer degrees.

	`timestamp:Number` (default = `0`) — Specifies the timestamp of the geolocation update.

Method Detail

clone

()

method

override public function clone():Event

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2

Creates a copy of the GeolocationEvent object and sets the value of each property to match that of the original.

Returns

Event — A new GeolocationEvent object with property values that match those of the original.

toString

()

method

override public function toString():String

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2

Returns a string that contains all the properties of the GeolocationEvent object. The string is in the following format:

[GeolocationEvent type=value bubbles=value cancelable=value status=value]

Returns

String — A string that contains all the properties of the GeolocationEvent object.

Constant Detail

UPDATE

Constant

public static const UPDATE:String = "update"

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Lite 4

Defines the value of the type property of a GeolocationEvent event object.

This event has the following properties:

Property	Value
`bubbles`	`false`
`cancelable`	`false`; there is no default behavior to cancel.
`currentTarget`	The object that is actively processing the event object with an event listener.
`target`	The Geolocation object receiving data.
