Method detail
degToDMS()method
public static function degToDMS(dec:Number, locals:Array = null, numDigits:Number = 1):String

Convert decimal degrees number into sexagecimal degrees string.

Parameters
dec:Number — decimal degrees.
 
locals:Array (default = null) — the axis direction (N, S) or (E, W). If undefined, null or empty, the leading minus will prefix the decimal degrees string.
 
numDigits:Number (default = 1) — number of figures in tenth of second.

Returns
String — the sexagecimal value whose syntax conforms with dmsToDeg() function.
dmsToDeg()method 
public static function dmsToDeg(dms:String):Number

Convert a string representation of a sexagecimal degrees into a numeric representation of decimal degrees.

Parameters
dms:String — a sexagecimal value. The supported syntax is : 
      \s?-?(\d{1,3})[.,°d]?\s?(\d{0,2})[']?\s?(\d{0,2})[.,]?(\d{0,})(?:["]|[']{2})?
      |
      \s?(\d{1,3})[.,°d]?\s?(\d{0,2})[']?\s?(\d{0,2})[.,]?(\d{0,})(?:["]|[']{2})?\s?([NSEW])?

Returns
Number — the decimal value or NaN if error occurs.
extend()method 
public static function extend(destination:Object, source:Object):Object

Copy all properties of a source object to a destination object. Modifies the passed in destination object.

Parameters
destination:Object — The object that will be modified
 
source:Object — The object with properties to be set on the destination

Returns
Object — The destination object
getArgs()method 
public static function getArgs(url:String = null):Object

Get Ags

Parameters
url:String (default = null)

Returns
Object — An object of key/value pairs from the query string
getParameterString()method 
public static function getParameterString(params:Object):String

Get parameter

Parameters
params:Object

Returns
String — A concatenation of the properties of an object in http parameter notation
hypot()method 
public function hypot(x:Number, y:Number):Number

Return sqrt(x2 +y2) without intermediate overflow or underflow. Special cases:

The computed result must be within 1 ulp of the exact result. If one parameter is held constant, the results must be semi-monotonic in the other parameter.

Parameters
x:Number — a value.
 
y:Number — a value.

Returns
Number — sqrt(x2 +y2) without intermediate overflow or underflow.
indexOf()method 
public static function indexOf(array:Array, obj:Object):int

Get the index of an object in an array

Parameters
array:Array — array containning items
 
obj:Object — Item that we find index

Returns
int — index of the item
mouseLeft()method 
public static function mouseLeft(evt:MouseEvent, can:DisplayObject):BooleanParameters
evt:MouseEvent
 
can:DisplayObject

Returns
Boolean
normalizeScale()method 
public static function normalizeScale(scale:Number):Number

Normalise scale

Parameters
scale:Number

Returns
Number — return a normalized scale value, in 1 / X format
pagePosition()method 
public static function pagePosition(forElement:Object):ArrayParameters
forElement:Object

Returns
Array
removeItem()method 
public static function removeItem(array:Array, item:Object):Array

Remove an item of an array

Parameters
array:Array — the array containing items
 
item:Object — item to remove

Returns
Array — the new array
upperCaseObject()method 
public static function upperCaseObject(object:Object):Object

Store all the keys of the Object in uppercase

Parameters
object:Object

Returns
Object — a new Object with all the same keys but uppercased
