import sailpoint.object.Filter;

import sailpoint.object.QueryOptions;

QueryOptions qOptions = new QueryOptions();

qOptions.addFilter(Filter.eq("workgroup",false));

int numberOfIdentities = context.countObjects(Identity.class, qOptions);

QueryOptions qOptions = new QueryOptions();

qOptions.addFilter(Filter.eq("workgroup",true));

int numberOfWorkGroups = context.countObjects(Identity.class, qOptions);

String message = "No of identities : "+numberOfIdentities+" No of workgroups : "+numberOfWorkGroups;

log.debug("message : "+message);
