4.2 Synchronizing Tasks on the Client

  • Article

The following example demonstrates a client’s request to synchronize its task data with the server, and the server’s response. In this example, the client does not submit any changes in the Sync command request ([MS-ASCMD] section 2.2.1.21), and the server responds with a Sync command response ([MS-ASCMD] section 2.2.1.21) that includes three changes: a new task, a changed task, and a deleted task. Elements of the Task class are included in the Sync command response as child elements of the airsync:ApplicationData element ([MS-ASCMD] section 2.2.3.11) under an airsync:Add element ([MS-ASCMD] section 2.2.3.7.2), an airsync:Change element ([MS-ASCMD] section 2.2.3.24), and an airsync:Delete element ([MS-ASCMD] section 2.2.3.42.2).
