public class Variable extends ConstrainableComponent<Variable> implements ExpressionContext
global variable: similar to Java "static public" variable. A global variable can be constant or modifiable denoted by the final field. A global variable has a name, a value and an alias. The value could be a general expression such as pi/4 where pi is another constant variable.

    • validate

      public void validate(List<SDKException> errors, List<SDKWarning> warnings)
      Description copied from class: DictionaryComponent
      Validate and append errors and warnings.
      Overrides:
      validate in class ConstrainableComponent<Variable>
      Parameters:
      errors - a List of error exceptions to append to.
      warnings - a List of warning exceptions to append to.

    • validate

      public void validate(List<SDKException> errors, List<SDKWarning> warnings, int modelChangeLowerBound, int ruleChangeLowerBound)
      Description copied from class: DictionaryObject
      Validate the RuleDictionary object. Append error and warning exceptions. Errors will cause RuleDictionary.update(java.util.List<oracle.rules.sdk2.exception.SDKWarning>) to throw an exception. A dictionary with warnings but no errors can be persisted.
      Overrides:
      validate in class DictionaryObject
      Parameters:
      errors - a List of error exceptions to append to.
      warnings - a List of warning exceptions to append to.
      modelChangeLowerBound - smallest ModelComponent.CreationUpdateNumber modified in thix tx.
      ruleChangeLowerBound - smallest RuleComponent.CreationUpdateNumber modified in thix tx. Rulesets and rules with UpdateNumber >= modelChangeLowerBound will be revalidated. a value of 0 will force revalidation of all rulesets. A value of Integer.MAX_VALUE will skip validation of all rulesets.

      public String[] getStoredPropertyNames()
      Overrides:
      getStoredPropertyNames in class ConstrainableComponent<Variable>
      Returns:
      Array of property names which are persisted in the order in which they appear in the schema.
