Class OssDaoOpenNMSImplSingleton

java.lang.Object

org.openoss.opennms.spring.dao.OssDaoOpenNMSImplSingleton

public class OssDaoOpenNMSImplSingleton
extends Object

Wrapper class for OssDaoOpenNMSImpl which makes it onto a singleton which can be shared between Qosd and QoSDrx when either one or or both applications are running. This is needed because Qosd and QoSDrx have different local application contexts but need to share access to the OssDao which provides the synchronized alarm cache for both applications. Either Qosd or QoSDrx can initialise the class. The first call to getInstance() causes the class to be created. All subsequent calls return the same instance. Note it is expected that the Spring application context has already set up the opennms DAO's before the first call to getInstance(). This means that you must ensure that the application contexts for Qosd and QosDrx set the same values for these DAO's otherwise there will be unpredictable results
