DeltaPacket interface (Flash Professional only)
ActionScript Interface Name
The DeltaPacket interface is provided by the
which is part of the data management functionality in Flash MX Professional 2004. (For more
information, see Chapter 14, "Data Integration (Flash Professional Only)," in Using Flash).
Typically the delta packet is used internally by resolver components.The DeltaPacket interface
and the related Delta interface and DeltaItem class let you manage changes made to the data.
These components have no visual appearance at runtime.
A delta packet is an optimized set of instructions that describe all changes that have been made to
the data in a data set. When the
component populates the
(by data binding) to a resolver component such as RDBMSResolver. The resolver converts the
delta packet into an update packet in the appropriate format.
Note: Unless you are writing your own custom resolver, it is unlikely you will ever need to know about
or write code that accesses methods or properties of a
A delta packet contains one or more deltas (see
on page 390), and each delta contains zero or more delta items (see
