public class AnyConverter
extends java.lang.Object

This class provides static methods which aim at exploring the contents of an Any and extracting its value. All public methods take an Object argument that either is the immediate object, such as Boolean, Type, interface implementation, or an Any that contains an object.
The methods which extract the value do a widening conversion. See the method comments for the respective conversions.
