8.8.8 パラメタ受渡しで使用するデータ型

　クライアント／サーバアプリケーションでパラメタ受渡しに使用するデータ型(オペレーション宣言)を以下に示します。

CORBAデータ型		in	out	inout	復帰値
long		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
short		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
unsigned long		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
unsigned short		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
long long		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
float		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
double		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
char		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
wchar		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
octet		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
boolean		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
enum		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
string	サイズ指定あり	TEXT	TEXT	TEXT	TEXT
	サイズ指定なし	TEXT	BY REFERENCE	BY REFERENCE	BY REFERENCE
wstring	サイズ指定あり	TEXT	TEXT	TEXT	TEXT
	サイズ指定なし	TEXT	BY REFERENCE	BY REFERENCE	BY REFERENCE
sequence		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
struct		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
union		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
fixed		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
Object		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE
TypeCode		BY REFERENCE	BY REFERENCE	BY REFERENCE	BY REFERENCE

注) TEXTはOOCOBOLの固定長テキストでNULL文字を含みません。

　クライアント／サーバアプリケーションでパラメタ受渡しに使用するデータ型(属性宣言)を以下に示します。

CORBAデータ型		set	get
long		BY REFERENCE	BY REFERENCE
short		BY REFERENCE	BY REFERENCE
unsigned long		BY REFERENCE	BY REFERENCE
unsigned short		BY REFERENCE	BY REFERENCE
long long		BY REFERENCE	BY REFERENCE
float		BY REFERENCE	BY REFERENCE
double		BY REFERENCE	BY REFERENCE
char		BY REFERENCE	BY REFERENCE
wchar		BY REFERENCE	BY REFERENCE
octet		BY REFERENCE	BY REFERENCE
boolean		BY REFERENCE	BY REFERENCE
enum		BY REFERENCE	BY REFERENCE
string	サイズ指定あり	TEXT	TEXT
	サイズ指定なし	BY REFERENCE	BY REFERENCE
wstring	サイズ指定あり	TEXT	TEXT
	サイズ指定なし	BY REFERENCE	BY REFERENCE
sequence		BY REFERENCE	BY REFERENCE
struct		BY REFERENCE	BY REFERENCE
union		BY REFERENCE	BY REFERENCE
fixed		BY REFERENCE	BY REFERENCE
Object		BY REFERENCE	BY REFERENCE
TypeCode		BY REFERENCE	BY REFERENCE

注) TEXTはOOCOBOLの固定長テキストでNULL文字を含みません。

注意事項

(1)NULLポインタの設定について

　サーバアプリケーションでのout, inoutパラメタ、復帰値、およびクライアントアプリケーションでのin,inoutパラメタでは、文字列型、シーケンス型、構造体、共用体でNULLオブジェクトを設定することができません。

(2)データ型の扱いについて

　固定長sequenceの場合、lengthにmaximumを超える値を設定した場合、maximumがlengthに設定されます。指定したlengthは無効になります。
