Method Detail

evaluateDecisionTableById

DmnDecisionTableResult evaluateDecisionTableById(String decisionDefinitionId,
                                               Map<String,Object> variables)

Evaluates the decision with the given id.

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 case 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 case 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,

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.
