DASResourcesUtil

public class DASResourcesUtil extends ResourcesUtil
This class overrides the isReferenced method in the ResourcesUtil class. An instance of this class is always returned when ResourcesUtil.getInstance() happens in the DAS
author

version

Fields Summary
boolean
noReferenceCheckNeeded
Flags if a getConnection call is coming from the connector runtime. Only for such a call, we should not be checking isReferenced The reason for this is that the getConnection call might be happening in the DAS for a jdbc resource which does not have a resource-ref in the DAS. However, we still need to give a connection from that resource, so we should not check for referencing info.
