Class Attribute<T>

java.lang.Object

org.glassfish.pfl.dynamic.codegen.impl.Attribute<T>

public class Attribute<T>
extends Object

Class used to define dynamic attributes on AttributedObject instances. Note that T cannot be a generic type, due to problems with Class<T> when T is a generic. To work around this problem, simply create an interface that extends the generic type (you are programming to interfaces, right?).
