Index of all Fields and Methods

A

Action(Updateable, Hashtable). Constructor for class logic.Action

This constructor handles all the more complicated scenarios in which more is required from an action then setting a single attribute.

Action(Updateable, Object). Constructor for class logic.Action

This is the "default" constructor -- it handles the simple case in which the required action simply sets a value in the Updateable object.

actions. Variable in class logic.Invoker

addRule(String, Action). Method in class logic.Rules

This method adds a new boolean-sequence / action pair to the rules Hashtable.

attribute. Variable in class logic.Action

This is an attribute that is passed in and set with the "typical" constructor, following the default framework behavior.

doUpdate(Hashtable). Method in interface logic.Updateable

Default behavior: if the Action that calls this method is simply setting the value of an attribute, the method body for doUpdate should look like this (for concreteness, we'll assume the attribute is a String -- you must cast the Hashtable value val to the appropriate type)

      Object val = vals.get(Action.MAIN_KEY);
      setValue((String)val);
