5.4 The Complete Specification

All that remains is to combine the preceding pieces of IDL into a single specification. As good IDL citizens, we wrap everything in a module called CCS and use a pragma to establish a unique prefix for repository IDs:

#pragma prefix "acme.com"
module CCS {	AssetType;
typedef unsigned long
typedef string	ModelType;
typedef short	TempType;
typedef string	LocType;

interface Thermometer {		model;
readonly attribute ModelType
readonly attribute AssetType		asset_num;
readonly attribute TempType		temperature;
attribute LocType		location;
};
interface Thermostat : Thermometer {
struct BtData {
TempType	requested;
TempType	min_permitted;
TempType	max_permitted;
string	error_msg;
};
exception BadTemp { BtData details; };
TempType	get_nominal();
TempType	set_nominal(in TempType new_temp)
};	raises(BadTemp);
interface Controller {		ThermometerSeq;
typedef sequence<Thermometer>
typedef sequence<Thermostat>		ThermostatSeq;

enum SearchCriterion { ASSET, LOCATION, MODEL }; union KeyType switch(SearchCriterion) {

case ASSET:

AssetType asset_num; case LOCATION:

LocType loc; case MODEL:

ModelType model_desc;

};

struct SearchType { KeyType key; Thermometer device;

};		SearchSeq;
typedef sequence<SearchType>
struct ErrorDetails {	tmstat_ref;
Thermostat
Thermostat::BtData	info;
};		ErrSeq;
typedef sequence<ErrorDetails>
exception EChange {

ErrSeq errors;

};

void	change(

	) raises(EChange);

};
