Class ServiceManagerCache

java.lang.Object

com.sap.cds.feature.mt.lib.subscription.ServiceManagerCache

All Implemented Interfaces:

HanaAccess

public class ServiceManagerCache
extends Object
implements HanaAccess

For performance reasons the SM should not be accessed with single requests.Therefore, a cache is used that is filled by a scheduled executer at a configurable time interval. It uses method getManagedInstances() to get all information with one request. Operations that must be accurate, use a forceCacheUpdate flag to enforce SM access.
