This interface provides the standard mechanism for an assistive technology to determine and set the graphical representation of an object. Applications can determine if an object supports the AccessibleComponent interface by first obtaining its AccessibleContext and then calling the <A HREF="../../javax/accessibility/AccessibleContext.html#getAccessibleComponent()"><CODE>AccessibleContext.getAccessibleComponent()</CODE></A> method.
