Method Detail

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.

evaluateDecisionTableByKey

DecisionEvaluationBuilder evaluateDecisionTableByKey(String decisionDefinitionKey)

Returns a fluent builder to evaluate the decision with the given key. The builder can be used to set further properties and specify evaluation instructions.

Parameters:

decisionDefinitionKey - the key of the decision definition, cannot be null.

Returns:

a builder to evaluate a decision

evaluateDecisionTableById

DecisionEvaluationBuilder evaluateDecisionTableById(String decisionDefinitionId)

Returns a fluent builder to evaluate the decision with the given id. The builder can be used to set further properties and specify evaluation instructions.

Parameters:

decisionDefinitionId - the id of the decision definition, cannot be null.

Returns:

a builder to evaluate a decision
