public class DTAction extends Action
A DTAction is an action that may be selected by any rule in the decision table, optionally with different parameters per rule. A Decision Table Action extends Action and contains
  • a DTActionNodeTable that contains a DTActionNode for every rule on the sheet
  • a boolean "parameterized" property that indicates whether the Action and the DTActionNode must be combined to form the rule action.
  • a boolean "alwaysSelected" property that indicates the "actionSelected" property of each DTActionNode is true and cannot be de-selected.
Any Action FORM may be used and any Expression it contains (even nested ones) can be parameterized. Parameterization uses DTActionParameterName (PROP_DT_ACTION_PARAMETER_NAME) property on the Expressions contained in the action.

An ASSIGN_NEW action must be alwaysSelected.

When the UI supplies action parameters, it should name those parameters that are to be supplied by the DTActionNodes by setting its DTActionParameterName property. Any expression value supplied becomes the default value if one is not supplied for the node.
