### Question:
IidSflowNameUtil { public static String createFlowCacheName(InstanceIdentifier<Classifier> classifierIid, FlowCacheCons.Value value) { PolicyRuleGroupKey policyRuleGroup = classifierIid.firstKeyOf(PolicyRuleGroup.class); ResolvedRuleKey resolvedRule = classifierIid.firstKeyOf(ResolvedRule.class); ClassifierKey classifier = classifierIid.firstKeyOf(Classifier.class); StringBuilder sb = new StringBuilder(); sb.append(createStringFromCompositeKey(policyRuleGroup.getTenantId().getValue(), policyRuleGroup.getContractId().getValue(), policyRuleGroup.getSubjectName().getValue())) .append(DELIMETER) .append(resolvedRule.getName().getValue()) .append(DELIMETER) .append(classifier.getName().getValue()) .append(DELIMETER) .append(value.get()); return sb.toString(); }  static String createFlowCacheName(InstanceIdentifier<Classifier> classifierIid, FlowCacheCons.Value value); static ContractId resolveContractIdFromFlowCacheName(String flowCacheName); static SubjectName resolveSubjectNameFromFlowCacheName(String flowCacheName); static RuleName resolveRuleNameFromFlowCacheName(String flowCacheName); static ClassifierName resolveClassifierNameFromFlowCacheName(String flowCacheName); static String resolveFlowCacheValue(String flowCacheName); static final String DELIMETER; static final String KEY_DELIMETER; }### Answer:
@Test public void testCreateFlowCacheName() { InstanceIdentifier<Classifier> classifierIid = TestUtils.getClassifierIid( ResolvedPolicyClassifierListener.resolveClassifiers(resolvedPolicy, rpIid)); assertEquals(testName, IidSflowNameUtil.createFlowCacheName(classifierIid, FlowCacheCons.Value.BYTES)); }
