Direct Known Subclasses:

JavaClass

public class JavaInstance
extends LuaUserdata

LuaValue that represents a Java instance.

Will respond to get() and set() by returning field values or methods.

This class is not used directly. It is returned by calls to CoerceJavaToLua.coerce(Object) when a subclass of Object is supplied.
