### Question:
SecRuleNameDecoder { public static ClassifierName getClassifierInstanceName(SecurityRule secRule) { StringBuilder keyBuilder = new StringBuilder(); Integer portMin = secRule.getPortRangeMin(); Integer portMax = secRule.getPortRangeMax(); if (portMin != null && portMax != null) { keyBuilder.append(L4ClassifierDefinition.DEFINITION.getName().getValue()); if (portMin.equals(portMax)) { keyBuilder.append(MappingUtils.NAME_DELIMETER) .append(L4ClassifierDefinition.DST_PORT_PARAM) .append(MappingUtils.NAME_VALUE_DELIMETER) .append(portMin.longValue()); } else { keyBuilder.append(MappingUtils.NAME_DELIMETER) .append(L4ClassifierDefinition.DST_PORT_RANGE_PARAM) .append(MIN_PORT) .append(MappingUtils.NAME_VALUE_DELIMETER) .append(portMin.longValue()) .append(MAX_PORT) .append(MappingUtils.NAME_VALUE_DELIMETER) .append(portMax.longValue()); } } SecurityRuleAttributes.Protocol protocol = secRule.getProtocol(); if (protocol != null) { if (keyBuilder.length() > 0) { keyBuilder.append(MappingUtils.NAME_DOUBLE_DELIMETER); } String protocolString = ""; if (protocol.getUint8() != null) { protocolString = protocol.getUint8().toString(); } else if (protocol.getIdentityref() != null) { protocolString = protocol.getIdentityref().getSimpleName(); } keyBuilder.append(IpProtoClassifierDefinition.DEFINITION.getName().getValue()) .append(MappingUtils.NAME_VALUE_DELIMETER) .append(protocolString); } Class<? extends EthertypeBase> ethertype = secRule.getEthertype(); if (ethertype != null) { if (keyBuilder.length() > 0) { keyBuilder.append(MappingUtils.NAME_DOUBLE_DELIMETER); } keyBuilder.append(EtherTypeClassifierDefinition.DEFINITION.getName().getValue()) .append(MappingUtils.NAME_VALUE_DELIMETER) .append(ethertype.getSimpleName()); } return new ClassifierName(keyBuilder.toString()); } private  SecRuleNameDecoder(); static SubjectName getSubjectName(SecurityRule secRule); static RuleName getRuleName(SecurityRule secRule); static ClassifierName getClassifierRefName(SecurityRule secRule); static ClassifierName getClassifierInstanceName(SecurityRule secRule); static ClauseName getClauseName(SecurityRule secRule);  }### Answer:
