DeltaItem class (Flash Professional only)
ActionScript Class Name
The DeltaItem class provides information about an individual operation performed on a transfer
object. It indicates whether a change was made directly to a property of the transfer object or
whether the change was made by a method call. It also provides the original state of properties on
a transfer object. For example, if the source of the delta packet was a data set, the DeltaItem object
contains information about any field that was edited.
In addition to the above, a DeltaItem object can contain server response information such as
current value and a message.
Use the DeltaItem class when accessing the changes in a delta packet. To access these changes, use
DeltaPacket.getIterator()
more DeltaItem instances, which you can access through
Delta.getChangeList()
