[唯讀] 語言版本: | ActionScript 3.0 |
產品版本: | Adobe Digital Enterprise Platform Data Services for Java EE 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
The time in UTC that this cached data was
first created in the local store.
This value is set when autoSave
is true
is called
and a fill()
, getItem()
,
or createItem()
request for data that is not already in the local
store is completed; or saveCache()
is called.
Invocations of these methods when the data is already cached will
change the last accessed time.
The last updated time will also be updated if the cached data is updated
as a result of the request.

The unique ID of the data cached.
This is the value that the service uses to uniquely identify this data.
For collections of items this is the value defined by the remote
destination when a fill request is made.
For single managed objects (SMOs) this is a map of name value pairs for
the item as defined by the <identity>
tag in
the services-config.xml file.

is called and a fill()
, getItem()
,
or createItem()
request for data that is not already in the local
store is completed; or saveCache()

The last write time will be updated if the cached data is updated
as a result of the request or a pushed update occurs
when autoSave

Provides access to custom information stored along with this data in the local store. Values assigned to this property must be serializable, that is, implement flash.util.IExternalizable or descend from no UI based objects. Typically this value is a string description of the data's relevance within the system. For example "All gold customers" or "All orders over $10K".

Contains true
if this query was synced when it was requested from the server.
A synced query is one for which the server pushes change notifications to the client.
Therefore, a true
value indicates an up to date, with respect to the server,
query at the time of its persistence to the local store.
