Method Detail

verifyDecisionTablesDoNotShareKeys

public void verifyDecisionTablesDoNotShareKeys(Collection<DecisionTableEntity> decisionTables)

Verifies that no two decision tables share the same key, to prevent database unique index violation.

Throws:

FlowableException - if any two decision tables have the same key

copyDeploymentValuesToDecisionTables

public void copyDeploymentValuesToDecisionTables(DmnDeploymentEntity deployment,
                                                 List<DecisionTableEntity> decisionTables)

Updates all the decision table entities to match the deployment's values for tenant, engine version, and deployment id.

setResourceNamesOnDecisionTables

public void setResourceNamesOnDecisionTables(ParsedDeployment parsedDeployment)

Updates all the decision table entities to have the correct resource names.

getMostRecentVersionOfDecisionTable

public DecisionTableEntity getMostRecentVersionOfDecisionTable(DecisionTableEntity decisionTable)

Gets the most recent persisted decision table that matches this one for tenant and key. If none is found, returns null. This method assumes that the tenant and key are properly set on the decision table entity.

getPersistedInstanceOfDecisionTable

public DecisionTableEntity getPersistedInstanceOfDecisionTable(DecisionTableEntity decisionTable)

Gets the persisted version of the already-deployed decision table. Note that this is different from getMostRecentVersionOfDecisionTable(org.flowable.dmn.engine.impl.persistence.entity.DecisionTableEntity) as it looks specifically for a decision table that is already persisted and attached to a particular deployment, rather than the latest version across all deployments.
