## org.apache.batik.swing.svg
Class SVGUserAgentAdapter

    java.lang.Object
      org.apache.batik.swing.svg.SVGUserAgentAdapter

All Implemented Interfaces:
  SVGUserAgent

Direct Known Subclasses:
  SVGUserAgentGUIAdapter

public class SVGUserAgentAdapter
extends java.lang.Object
implements SVGUserAgent

This Implements the SVGUserAgent interface to provide a very simple version of client services to the JSVGComponent. This implementation does not require any GUI interaction to work. This implementation is particularly bad about user interaction most of the alert,prompt,etc methods are totally useless. In a GUI environment you probably want to use SVGUserAgentGUIAdapter.
