constructEvent

public SystemEvent constructEvent(String originalItemId,
                                  String entityType,
                                  String propertyVal,

                                  EventWorkerType workerType)

Description copied from interface: CacheInvalidationHelper

Create a cache invalidation event

Specified by:

constructEvent in interface CacheInvalidationHelper

Returns:

addEventDetail

protected void addEventDetail(SystemEvent event,
                              String name,
                              String value)

constructRegionEvent

public SystemEvent constructRegionEvent(Long processMarker,
                                        String region,
                                        EventWorkerType workerType)

Description copied from interface: CacheInvalidationHelper

Create a cache invalidation event to invalidate an entire cache region

Specified by:

constructRegionEvent in interface CacheInvalidationHelper

Returns:

getInvalidationRegions

public List<EntityCacheRegion> getInvalidationRegions(String property,
                                                      Class<?>[] entityClass)

Description copied from interface: CacheInvalidationHelper

If the given property is not empty or and the given property is annotated with @Cache this will return the result of #getPropertyRegion(property, Class[]). In this case the returned list will be a single-element

If the given property is empty or is not annotated with @Cache then this will return the result of CacheInvalidationHelper.getTypeRegions(Class[])

If both the given property and the list of classes are marked with @Cache then this returns an empty list

Specified by:

getInvalidationRegions in interface CacheInvalidationHelper

See Also:

#getPropertyRegion(String, Class[])}, #getTypeRegions(Class[])}

getPropertyRegion

public EntityCacheRegion getPropertyRegion(String property,
                                           Class<?>[] entityClass)

Description copied from interface: CacheInvalidationHelper

Inspects the property for the given entityClass to look for an @Cache annotation marking the region in which this property is cached

Specified by:

getPropertyRegion in interface CacheInvalidationHelper

Returns:

the mapping of property cache region and which fully-qualified class name the property is apart of. If property is not cacheable then this returns null

getTypeRegions

public List<EntityCacheRegion> getTypeRegions(Class<?>[] entityClass)

Description copied from interface: CacheInvalidationHelper

Walks up the hierarchies of the given classes looking @Cache annotation values. For each one that is found, a list is built up of the region specified in the @Cache annotation and which fully-qualified type that it was found on. This is used to construct the eviction key for Hibernate.

This is designed to work in the following scenarios:

1. Broadleaf has an entity SkuImpl that is annotated with @Cache("blProducts")
2. There is an extension of SkuImpl called ExtendedSku
3. ExtendedSku does not have an @Cache annotation
4. Hibernate builds a cache key with the name SkuImpl inside of the blProducts cache as opposed to using the extended type name

1. Broadleaf has an entity SkuImpl that is annotated with @Cache("blProducts")
2. There is an extension of SkuImpl called ExtendedSku
3. ExtendedSku is annotated with @Cache("otherEntityCache")
4. Hibernate caches the name SkuImpl inside of the blProducts cache and caches the name ExtendedSku inside of the otherEntityCache cache

Specified by:

getTypeRegions in interface CacheInvalidationHelper

Returns:

a list of mappings to which fully-qualified entity type is within which cache region. If no entities in the hierarchy are annotated with @Cache this returns an empty list
