Class AttributeKey<T>

  • public abstract class AttributeKey<T>
    extends Object
    Type-safe attribute accessor.

    Servlet API has a bag of stuff in several scopes (such as request, session, ...) but the API is not type-safe. This object provides a convenient type-safe access to to such bags, as well as providing uniform API regardless of the actual scope.

    Each instance of AttributeKey gets an unique attribute name, which means in the most typical case, these instances should be used as a singleton.
