public class DTActionNode extends UnnamedRuleComponent<DTActionNode> implements ExpressionContext
A DTActionNode tells each DTRule how to interpret its DTAction. A DTActionNode contains a boolean "selected" property that indicates if the corresponding DTRule should execute this action. If the DTAction is parameterized, then each DTActionNode contains a dynamic copy of the DTAction Action's ExpressionTable (parameter table). The copy is dynamic because only Expressions marked with the DTActionParameter property may be modified.

    • parentAction

      public Action parentAction()
      Overrides:
      parentAction in class RuleComponent<DTActionNode>

    • getActionSelectedProperty

      public SettableProperty<Boolean> getActionSelectedProperty()
      Get ActionSelected Property.
      Returns:
      Boolean SettableProperty

    • isActionSelected

      public boolean isActionSelected()
      Is Action Selected flag
      Returns:
      flag indicating whether the Action is selected for the Rule referencing this action node

    • setActionSelected

      public void setActionSelected(boolean selected)
      Set Action Selected flag
      Parameters:
      selected - whether the Action is selected for the Rule referencing this action node

    • getExpressionTableProperty

      public TableProperty<Expression> getExpressionTableProperty()

      Returns:
      Expression TableProperty

    • getExpressionTable

      public ExpressionTable getExpressionTable()
      Get Expression Table. The expressions are the DTAction parameters, and should be retrieved using getExpressionByDTActionParameterName(java.lang.String) Any changes to the DTAction should be followed by RuleDictionary.update(java.util.List<oracle.rules.sdk2.exception.SDKWarning>) before calling this method.
      Returns:
      ExpressionTable with parameters of the DTAction

    • getPropertyNames

    • validate

      public void validate(List<SDKException> errors, List<SDKWarning> warnings)
      Validate expression table: Adjusts DTAction parameters to be consistent with DTAction. Expressions should have "DTActionParameterName" non-empty. Duplicate names indicate a merge collision. Parameters are copied from the DTAction's ExpressionTable. They can be modified per rule.
      Overrides:
      validate in class DictionaryComponent<DTActionNode>
      Parameters:
      errors -
      warnings -

      Parameters:
      parameterName - name of DT action parameter
      Returns:
      Expression corresponding to value of named parameter, or null if no such parameter.

    • put

      public Object put(String key, Object value)
      Description copied from class: DictionaryComponent
      Generic property setter. Throws runtime exceptions for incorrect arguments. Please see the specific bean class for a list of properties, their types, and permissible values.

      A put() with either null key or null value throws a NullPointerException.

      A put() with a key that is not a String throws a ClassCastException

      A put() of a value that is not of the correct type for the key throws a ClassCastException.

      Bean properties which have no set() method are read only, and cannot be modified using the put(). Attempting to do so throws a runtime IllegalArgumentException. PROP_ID, and PROP_*_SELECTED are always read only.

      Specified by:
      put in interface Map<String,Object>
      Overrides:
      put in class UnnamedRuleComponent<DTActionNode>
      Parameters:
      key - the key of the property to set
      value - the value of the named property to set
      Returns:
      the previous value of the property
