Constructor Details

SearchParamIdentityCacheSvcImpl

public SearchParamIdentityCacheSvcImpl(JpaStorageSettings theStorageSettings,
 IResourceIndexedSearchParamIdentityDao theResourceIndexedSearchParamIdentityDao,
 org.springframework.transaction.PlatformTransactionManager theTxManager,
 MemoryCacheService theMemoryCacheService)

Method Details

start

@PostConstruct
public void start()

preDestroy

@PreDestroy
public void preDestroy()

initCache

protected void initCache()

Initializes the cache by preloading search parameter identities IndexedSearchParamIdentity.

hasInFlightTasks

public boolean hasInFlightTasks()

Specified by:

hasInFlightTasks in interface ISearchParamIdentityCacheSvc

findOrCreateSearchParamIdentity

public void findOrCreateSearchParamIdentity(Long theHashIdentity,
 String theResourceType,
 String theParamName)

Asynchronously ensures that a IndexedSearchParamIdentity exists for the given hash identity, parameter name, and resource type. If the identity is already present in the in-memory cache, no action is taken.

If the identity is missing, a SearchParamIdentityCacheSvcImpl.PersistSearchParameterIdentityTask is created and submitted for asynchronous execution. To avoid modifying the cache during an active transaction, task submission is deferred until after the transaction is committed.

Specified by:

findOrCreateSearchParamIdentity in interface ISearchParamIdentityCacheSvc

Parameters:

theHashIdentity - The hash identity representing the search parameter.

theResourceType - The resource type (e.g., "Patient", "Observation").

theParamName - The search parameter name.
