Delta interface (Flash Professional only)

ActionScript Interface Name mx.data.components.datasetclasses.Delta

The Delta interface provides access to the transfer object, collection, and transfer object-level changes. With this interface you can access the new and previous values in a transfer object. For example, if the delta packet was obtained from a data set, each delta would represent an added, edited, or deleted row.

The Delta interface also provides access to messages returned by the associated server-side process. For more information on client-server interactions, see RDBMSResolver component (Flash Professional only).

Use the Delta interface to examine the delta packet before sending changes to the server and to review messages returned from server-side processing.
