DataSet class (Flash Professional only)
Inheritance MovieClip > DataSet
ActionScript Class Name
The DataSet component lets you work with data as collections of objects that can be indexed,
sorted, searched, filtered, and modified.
The DataSet component functionality includes DataSetIterator, a set of methods for traversing
and manipulating a data collection, and DeltaPacket, a set of interfaces and classes for working
with updates to a data collection. In most cases, you don't use these classes and interfaces directly;
you use them indirectly through methods provided by the DataSet class.
