ActionDescriptor
This object provides a dictionary-style mechanism for storing data as key-value pairs. It can be used for
low-level access into Photoshop. See an example of this usage in ‘
Selection sample script’ on page 168.
Many configuration files use serialized action descriptors to represent their data. It is used, for example, to
encapsulate playback options in Application
.playbackParameters, and is returned by
Application
.getCustomOptions().
