Property detail
MINIMUM_HEIGHTproperty
public static var MINIMUM_HEIGHT:Number = 138

The minimum height required to be able to display the settings panel within the SWF

MINIMUM_WIDTHproperty 
public static var MINIMUM_WIDTH:Number = 215

The minimum width required to be able to display the settings panel within the SWF

Constructor detail
SWFStore()constructor
public function SWFStore()

Creates a store, which can be used to set and get information on a user's local machine. This is typically invoked through the YUI JS API.

If multiple SWF files need access to the same store, or if the SWF file that creates a store will later be moved, the value of this parameter affects how accessible the store will be.

For example, if you create a store with localPath set to the default value (the full path to the SWF file), no other SWF file can access that shared object. If you later move the original SWF file to another location, not even that SWF file can access the data already stored.

To avoid inadvertently restricting access to a store, set this parameter. The most permissive approach is to set localPath to / (forward slash), which makes the store available to all SWF files in the domain, but increases the likelihood of name conflicts with other stores in the domain. A more restrictive approach is to append localPath with folder names that are in the full path to the SWF file. Note that not just any folder path can be placed here, but only those that are in the path of the SWF. For instance, if the SWF is located at company.com/products/mail/mail.swf, the available options for localPath would be "/products/mail/", "/products/", or "/".

Method detail
calculateCurrentSize()method
public function calculateCurrentSize():uint

Gets the amount of space taken by the current store. Note that this value is calculated as requested, so large datasets could result in reduced performance.

Returns
uint — the size of the store in KB
clear()method 
public function clear():Boolean

Removes all data in local storage for this domain.

Be careful when using this method, as it may remove stored information that is used by other applications in this domain

Returns
Boolean — Whether the clear was successful
displaySettings()method 
public function displaySettings():void

Displays the settings dialog to allow the user to configure storage settings manually. If the SWF height and width are smaller than what is allowable to display the local settings panel, an error message will be sent to JavaScript.

getItems()method 
public function getItems():Array

Returns the storage object as an Array of name/value pairs.

Returns
Array — The storage dictionary as an Array
getLength()method 
public function getLength():int

Returns the number of keys in storage.

Returns
int — The number of keys
getModificationDate()method 
public function getModificationDate():Date

Gets the timestamp of the last store. This value is automatically set when data is stored.

Returns
Date — A Date object
getNameAt()method 
public function getNameAt(index:int):String

Returns the key name in storage, if any, at the specified index.

Parameters
index:int — The index of the "cookie" or store

Returns
String — The data
getPath()method 
public function getPath(path:String):String

Expands a path with shorthands to url

Parameters
path:String — Path with shorthands

Returns
String — Path with shorthands expanded
getShareData()method 
public function getShareData():Boolean

Whether or not to data is being shared among different browsers

Returns
Boolean
getTypeAt()method 
public function getTypeAt(index:int):String

Returns the data type of of the storage.

Parameters
index:int — The index of the "cookie" or store

Returns
String — The data type.

getTypeOf
getTypeOf()method 
public function getTypeOf(location:String):String

Returns the data type of of the storage.

May be one of the following types:

Parameters
location:String — The name of the "cookie" or store

Returns
String — The data type.
getUseCompression()method 
public function getUseCompression():Boolean

Whether or not compression is used

Returns
Boolean
getValueAt()method 
public function getValueAt(index:int):*

Returns the value of the key in local storage, if any, at the specified index. Corresponds to the key(n) method in the HTML5 spec.

Parameters
index:int — The index of the "cookie" or store

Returns
* — The value stored
getValueOf()method 
public function getValueOf(location:String):*

Returns the value of the key in local storage, if any. This corresponds to the HTML5 spec getItem(key).

Note: to return an item at a specific index, use the helper function

: getValueAt(index) Parameters
location:String — The name of the "cookie" or key

Returns
* — The data

getValueAt
hasAdequateDimensions()method 
public function hasAdequateDimensions():Boolean

Helper function to determine if SWF visible area is large enough to fit the settings panel

Returns
Boolean — Boolean Whether or not the area is large enough.
initializeSharedObject()method 
protected function initializeSharedObject():void
removeItem()method 
public function removeItem(location:String):Boolean

Removes the data in local storage at the specified location, if any.

Parameters
location:String — The name of the "cookie" or store

Returns
Boolean — Whether the remove was successful
removeItemAt()method 
public function removeItemAt(index:int):Boolean

Removes the data in local storage at the specified location, if any.

Parameters
index:int — The name of the "cookie" or store

Returns
Boolean — Whether the remove was successful
setItem()method 
public function setItem(location:String, item:*):Boolean

Saves data to local storage. It returns "true" if the storage succeeded; "false" if the user has denied storage on their machine or if the current limit is too low.

The size limit for the passed parameters is ~40Kb.

Parameters
location:String — The data to store
 
item:* — The name of the "cookie" or store

Returns
Boolean — Boolean Whether or not the save was successful
setShareData()method 
public function setShareData(value:Boolean):void

Whether or not to share data among different browsers

Parameters
value:Boolean
setSize()method 
public function setSize(value:int):String

This method requests more storage if the amount is above the current limit (typically ~100KB). The request dialog has to be displayed within the Flash player itself so the SWF it is called from must be visible and at least 215px x 138px in size. Since this is a "per domain" setting, you can use this method on a SWF in a separate page, such as a settings page, if the width/height of the compiled SWF is not large enough to fit this dialog.

Parameters
value:int — The size, in KB

Returns
String
setUseCompression()method 
public function setUseCompression(value:Boolean):void

Whether or not to use compression

Parameters
value:Boolean
