DataStore.currentBatch
property. Changes you make such as property changes detected automatically through
data binding, createItem(), updateItem(), or deleteItem() operations are stored in this
batch. The current list of uncommitted batches is stored in the uncommittedBatches property.
You call createBatch create a new batch which is added to the end of the list. This batch
is automatically made the currentBatch.
You can commit or revert the set of a changes a batch at a time - in both cases, the batch is
automatically removed from the uncommittedBatches list.
When there are dependencies between changes, you should commit and revert changes in order - i.e. commit the oldest batch in the list (uncommittedBatches[0]) and revert the most recent batch - uncommittedBatches[uncommittedBatches.length - 1].
The commitRequired property is set to true when there are any changes in the batch
(i.e. items.length > 0). The items property stores the set of DataMessages in this batch.
You can store custom information in a MessageBatch via the properties
property. Batches are saved/restored each time you use the saveCache method
or automatically when autoSaveCache is true when using the offline feature.
Each batch also has a DataMessage associated with it in the batchMessage property.
If you need to communicate information with the server (and you are sending the batch
message to the server) you can store info in the headers of this message.

This method serializes the batch with the following stucture:
numberOfElements:int - this is the total number of elements serialized
[repeated element (once for every message in the batch)]
destination:String - the destination of the associated DataService
uid:String - the UID of the associated item
message:DataMessage - the message for the associated change
Because the message currently contains a copy of the item we don't have
to serialize the message in a special way. | MessageBatch | ||

batchMessage | 속성 |
public var batchMessage:DataMessage| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
This is the data message used to represent the batch being sent to the server. If you need to pass additional per-transaction information you might use the headers of this message to communicate with your server code (assuming it actually sends the message instead of converting it on the client).
commitRequired | 속성 |
commitRequired:Boolean [읽기 전용] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
True if any changes are in this batch. This is a bindable property.
이 속성은 데이터 바인딩에 대한 소스로 사용할 수 있습니다. 이 속성을 수정하면 propertyChange 이벤트를 전달합니다.
