Client-Side Communication ActionScript 89

To create “private” values for a shared object—values that are available only to the client instance

while the object is in use and are not stored with the object when it is closed—create properties

that are not named

data to store them, as shown in the following example.

so.favoriteColor = "blue";

so.favoriteNightClub = "The Bluenote Tavern";

so.favoriteSong = "My World is Blue";

Example

The following example sets the current stream to the user’s selection.

curStream = _root.so.data.msgList[selected].streamName;

SharedObject.onSync

SharedObject.flush

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

myLocalOrRemoteSharedObject.flush([minimumDiskSpace])

Parameters

minimumDiskSpace An optional integer specifying the number of bytes that must be allotted

for this object. The default value is 0.

Returns

A Boolean value of true or false, or a string value of "pending".

• If the user has permitted local information storage for objects from this domain, and the

amount of space allotted is sufficient to store the object, this method returns

true. (If you have

passed a value for minimumDiskSpace, the amount of space allotted must be at least equal to

that value for

true to be returned).

• If the user has permitted local information storage for objects from this domain, but the

amount of space allotted is not sufficient to store the object, this method returns

"pending".

• If the user has permanently denied local information storage for objects from this domain, or if

Flash is unable to save the object for any reason, this method returns

false.

Description

Method; immediately writes a locally persistent shared object to a local file. The shared object can

be remote or local; however, this method only writes the file locally. If you don’t use this method,

Flash writes the shared object to a file when the shared object session ends—that is, when the

SWF movie is closed, when the shared object is garbage-collected because it no longer has any

references to it, or when you call

SharedObject.close.

If this method returns

"pending", the Flash Player displays a dialog box asking the user to

increase the amount of disk space available to objects from this domain (see “Local disk space

considerations” on page 83). To allow space for the shared object to “grow” when it is saved in the

future, thus avoiding return values of

"pending", pass a value for minimumDiskSpace. When

Flash tries to write the file, it looks for the number of bytes passed to

minimumDiskSpace, instead

of looking for just enough space to save the shared object at its current size.
