Method Details

buildTenantTrackingAndArchivedFilter

public Optional<javax.persistence.criteria.Predicate> buildTenantTrackingAndArchivedFilter(javax.persistence.criteria.Root<?> trackableRootEntity,
 @Nullable
 com.broadleafcommerce.data.tracking.core.context.ContextInfo contextInfo,
 Map<String,Object> parameterValues,
 String trackingTenantIdParamName,
 javax.persistence.EntityManager entityManager)

Similar to logic in JpaNarrowExecutor. This is useful for queries that can't use JpaNarrowingHelper due to special configuration requirements such as needing to set TypedQuery.setLockMode(LockModeType).

Parameters:

trackableRootEntity - the query root

contextInfo - the context to build the criteria from

parameterValues - a map of query parameters and their values. Any new parameter will be added to this map.

trackingTenantIdParamName - if a filter is added on tracking tenant ID, this is the name of the parameter that will be used for it and added to parameterValues

entityManager - the entity manager to use for building criteria

Returns:

an Optional containing any tenant criteria that needs to be applied if applicable

createQueryAndGetResultList

public <R> List<R> createQueryAndGetResultList(javax.persistence.criteria.CriteriaQuery<R> criteria,
 @Nullable
 javax.persistence.LockModeType lockModeType,
 Map<String,Object> parameterValues,
 javax.persistence.EntityManager entityManager)

Simplifies the process of creating a TypedQuery, setting parameters, and getting the results.

Type Parameters:

R - the result element type

Parameters:

criteria - the criteria to build the query from

lockModeType - (optional) the lock mode to set on the query

parameterValues - query parameter values to set on the query

entityManager - the entity manager to use

Returns:

the result list of the query
