public class ArgumentData
extends NodeData

Data container for UPnP action argument information.

This class extends NodeData to represent action argument definitions from UPnP service descriptions. It encapsulates metadata about action arguments including their values, directions, and related state variables.

Key features:

• Argument value storage
• Direction (in/out) management
• Related state variable association
• XML node data inheritance
• Argument metadata handling

This class is used by UPnP actions to manage argument definitions and their values during action invocation, enabling proper parameter handling and response generation.
