Method Detail

getCodeSystemId

public static Integer getCodeSystemId(String systemName)

Retrieves the id for the passed system, for the current tenant-datastore. If not found, null is returned.

Parameters:

parameter - The name of a code system

Returns:

Integer The id corresponding to the passed code system

putCodeSystemId

public static void putCodeSystemId(String tenantDatastoreCacheName,
                                   String systemName,
                                   Integer systemId)

Adds the passed code system name and id to the current tenant-datastore cache.

Parameters:

tenantDatastoreCacheName - The name of the datastore-specific cache the entry should be added to.

systemName - A valid code system name.

systemId - The id associated with the passed code system name.

putCodeSystemIds

public static void putCodeSystemIds(String tenantDatastoreCacheName,
                                    Map<String,Integer> newCodeSystems)

Adds the passed code system name/id pairs to the the current tenant-datastore cache.

Parameters:

tenantDatastoreCacheName - The name of the datastore-specific cache the entry should be added to.

newParameters - A Map containing code system name/id pairs.

getCacheNameForTenantDatastore

public static String getCacheNameForTenantDatastore()

Returns a String containing a combination of the current tenantId and datastoreId.

Returns:

dumpCacheContents

public static String dumpCacheContents()

Returns:

String - A formatted representation of the entire cache managed by this class.

reportCacheDiscrepancies

public static String reportCacheDiscrepancies(ParameterDAO dao)

Determines and reports any discrepancies between the current thread's Code Systems cache and the contents of the database CODE_SYSTEMS table.

Parameters:

dao - A Parameter DAO instance

Returns:

String - A report detailing cache/db discrepancies.
