    • evaluateDecisionTableById

      DmnDecisionTableResult evaluateDecisionTableById(String decisionDefinitionId, Map<String,Object> variables)
      Evaluates the decision with the given id.
      Parameters:
      decisionDefinitionId - the id of the decision definition, cannot be null.
      variables - the input values of the decision.
      Returns:
      the result of the evaluation.
      Throws:
      NotFoundException - when no decision definition is deployed with the given id.
      NotValidException - when the given decision definition id is null.
      AuthorizationException - if the user has no Permissions.CREATE_INSTANCE permission on Resources.DECISION_DEFINITION.

    • evaluateDecisionTableByKey

      DmnDecisionTableResult evaluateDecisionTableByKey(String decisionDefinitionKey, Map<String,Object> variables)
      Evaluates the decision with the given key in the latest version.
      Parameters:
      decisionDefinitionKey - the key of the decision definition, cannot be null.
      variables - the input values of the decision.
      Returns:
      the result of the evaluation.
      Throws:
      NotFoundException - when no decision definition is deployed with the given key.
      NotValidException - when the given decision definition key is null.
      AuthorizationException - if the user has no Permissions.CREATE_INSTANCE permission on Resources.DECISION_DEFINITION.

    • evaluateDecisionTableByKeyAndVersion

      DmnDecisionTableResult evaluateDecisionTableByKeyAndVersion(String decisionDefinitionKey, Integer version, Map<String,Object> variables)
      Evaluates the decision with the given key in the specified version. If no version is provided then the latest version of the decision definition is taken.
      Parameters:
      decisionDefinitionKey - the key of the decision definition, cannot be null.
      version - the version of the decision definition. If null then the latest version is taken.
      variables - the input values of the decision.
      Returns:
      the result of the evaluation.
      Throws:
      NotFoundException - when no decision definition is deployed with the given key and version.
      NotValidException - when the given decision definition key is null.
      AuthorizationException - if the user has no Permissions.CREATE_INSTANCE permission on Resources.DECISION_DEFINITION.
