7. データ型
7.1 データの直列化
全てのデータ型はシリアルデータリンク上で転送するためにバイナリストリームへ直列化されなければなりません。それぞれのデータ型の直列化は下記の法則で順番にマシンのメモリ上に構築されるバイト列の転送によって行われます。
- データ構造のメンバーはそれらが型定義に現れるのと同じ順序でメモリに保存されます。
- 全てのデータ構造はパックされます。これは使用されていない "埋め" バイトがデータ構造のメンバー間に存在しないことを意味します。
- マルチバイトの数値型はリトルエンディアンフォーマットでメモリに保存されます。これは下位バイトがメモリの最初に現れ、続いて上位バイトへ向かう順にメモリ上に配置されることを意味します。
7.2 文字セット
特に明記しない限り全てのデバイスは ASCII 文字セットを受け入れます。文字列型を持ついくつかの項目は以下に示す ASCII 文字の特定のサブセットのみとなるかも知れません。
| ユーザウェイポイント識別子: | 大文字、数字 |
| ウェイポイントコメント: | 大文字、数字、空白、ハイフン |
| ルートコメント: | 大文字、数字、空白、ハイフン |
| 町(City): | デバイスによって無視 |
| 県(State): | デバイスによって無視 |
| Facility Name: | デバイスによって無視 |
| 国コード: | 大文字、数字、空白 |
| ルート識別子: | 大文字、数字、空白、ハイフン |
| ルートウェイポイント識別子: | 全ての ASCII 文字 |
| リンク識別子: | 全ての ASCII 文字 |
| トラック識別子: | 大文字、数字、空白、ハイフン |
いくつかのデバイスは上記に示した文字セット以上の文字を許可しているかもしれませんが、このドキュメントではデバイス固有の追加文字セットを示すことは行いません。
7.3 基本データ型
以下はより複雑なデータ型の定義で使用される基本データ型です。
7.3.1 char
char データ型は 8 ビットサイズです。
7.3.2 文字配列
特に明記しない限り、全ての文字配列は空白でパディングされ null 終端子を必要としません。例えば以下のデータ型を考えます:
char xyz[6]; /* xyz type */
単語 "CAT" はこのデータ型に以下のように格納されるでしょう:
xyz[0] = ‘C’; xyz[1] = ‘A’; xyz[2] = ‘T’; xyz[3] = ‘ ’; xyz[4] = ‘ ’; xyz[5] = ‘ ’;
文字配列はホストとデバイス間で文字列を転送する方法を提供します。しかし文字配列はデバイスが文字列に割り当てている文字数を超えて転送されるかもしれません。この場合、デバイスはデバイスが文字列に割り当てているサイズを超えた全ての文字を無視します。例えば "cmnt" 文字配列は 40 文字の転送を許可していますが、デバイスは "cmnt" 文字列に 16 文字だけしか持てない可能性があります。この場合、デバイスは転送された文字配列の後ろの 24 文字を無視します。
7.3.3 可変長文字列
文字配列とは対照的に、可変長文字列は、データパケットがデータパケットサイズの最大容量より大きくなる事を引き起こさないような、どのような長さともなる null 終端文字列です。可変長文字列がデータ構造のメンバーである場合、データ型は以下のように記述されています:
typedef struct
{
sint16 abc;
/* char xyz[] null 終端文字列 */
sint16 def;
} example_type;
この構文は xyz と名付けられた可変長文字列がデータ構造のメンバー abc と def の間に出現する事を示しています。従って、dev メンバーの (データ構造先頭からの) アドレスオフセットは実行時になるまで (可変長文字列が配置されるまで) 不明となります。実行時でのアドレスオフセット計算の必要を最小化するため、可能な限り可変長文字列はデータ構造の最後に配置されています。
7.3.4 uint8
uint8 データ型は 8 ビット無符号整数に対して使用します。
7.3.5 uint16
uint16 データ型は 16 ビット無符号整数に対して使用します。
7.3.6 uint32
uint32 データ型は 32 ビット無符号整数に対して使用します。
7.3.7 sint16
sint16 データ型は 16 ビット有符号整数に対して使用します。
7.3.8 sint32
sint32 データ型は 32 ビット有符号整数に対して使用します。
7.3.9 float32
float32 データ型は 32 ビット IEEE フォーマット浮動小数点データ (1 符号ビット, 8 指数ビット, 23 仮数ビット) です。
7.3.10 float64
float64 データ型は 64 ビット IEEE フォーマット浮動小数点データ (1 符号ビット, 11 指数ビット, 52 仮数ビット) です。
7.3.11 bool
bool データ型は true (非ゼロ) または false (ゼロ) を示すために使う 8 ビット整数です。
7.3.12 position_type
position_type は半球上での緯度と経度を示すために使用されます。ここで半球の 231 は 180 度と同じです。北緯と東経は正の数、南緯と西経は負の数となります。
typedef struct
{
sint32 lat; /* 半球の緯度 */
sint32 lon; /* 半球の経度 */
} position_type;
以下の変換は度と半球の変換方法を表しています。
\[ \begin{align*} {\rm degrees} & = {\rm semicircles} \times (180 + 2^{31}) \\ {\rm semicircles} & = {\rm degrees} \times (2^{31} \div 180) \end{align*} \]7.3.13 radian_position_type
radian_position_type は弧度法で緯度と経度を示すために使用されます。ここで \(\pi\) ラジアンは 180 度と同じです。北緯と東経は正の数、南緯と西経は負の数となります。
typedef struct
{
float64 lat; /* 弧度法の緯度 */
float64 lon; /* 弧度法の経度 */
} radian_position_type;
以下の変換は度とラジアンの変換方法を表しています。
\[ \begin{align*} {\rm degrees} & = {\rm radians} \times (180 \div \pi) \\ {\rm radians} & = {\rm degrees} \times (\pi \div 180) \end{align*} \]7.3.14 time_type
time_type は絶対時刻を示すためにいくつかのデータ構造で使用されています。これは 32 ビット無符号整数であり、値は 1990/01/01 00:00:00 (UTC) からの経過秒数です。
7.3.15 symbol_type
symbol_type はウェイポイントの記号を示すために特定のデバイスで使用されています。
typedef uint16 symbol_type;
symbol_type 値を以下に列挙します。この型を使用する大部分のデバイスがここで提示した記号の非常の小さなサブセットのみに限定されている事に注意してください。それぞれのデバイスにどのようなサブセットが適用されるかについてはこのドキュメントでは記述していません。しかし、デバイスは受信した未許可の全ての記号を無視し、一般的なドット記号の値に置き換えるでしょう。従って、要求した値をデバイスが受け入れない可能性以外は、以下の表で示しているどの値を使用しても危害となることはありません。

ゼロ: ユーザウェイポイントを示す (“subclass” は無視されます). 非ゼロ: 非ユーザウェイポイントを示す (“subclass” が有効でなければならない).
(デバイスマップデータベースの町のような) 非ユーザウェイポイントに対してデバイスは "wpt_class" メンバーに非ゼロ値を提供し、"subclass" メンバーは非ユーザウェイポイントをより詳しく識別するための有効なデータを含んでいます。もしホストが (ルートの一部のように) このウェイポイントをデバイスから転送して戻す場合、ホストは "wpt_class" と "subclass" メンバーを無修正のままにしなければいけません。ユーザウェイポイントに対してはホストは "wpt_class" を確実にゼロにしなければいけません。このとき "subclass" メンバーは無視されますがゼロに設定すべきです。
"lnk_ident" メンバーはルート中の前ウェイポイントからこのウェイポイントまでの経路の名前を示す文字列です。"HIGHWAY 101" は直前のウェイポイントからこのウェイポイントまでの経路がハイウェイ 101 沿いである事を示すために "lnk_ident" に設定されるでしょう。"lnk_ident" 文字列は空にする事ができます (null 終端子のみ)。これはパスに関して特記する事がない事を示します。

wpt_cat - Waypoint Category. May not be supported by all devices. Default value is 0x0000. This is a bit field that provides category membership information for the waypoint. The waypoint may be a member of up to 16 categories. If a bit is set then the waypoint is a member of the corresponding category. For example, if bits 0 and 4 are set then the waypoint is a member of categories 1 and 5. For more information see section 6.5 on page 13.
temp - Temperature. May not be supported by all devices. A value of 1.0e25 in this field indicates that this parameter is not supported or is unknown for this waypoint.
time - Time. May not be supported by all devices. A value of 0xFFFFFFFF in this field indicates that this parameter is not supported or is unknown for this waypoint.
attr - Attribute. Must be 0x80 for D110_Wpt_Type.
dspl_color - The 'dspl_color' member contains three fields; bits 0-4 specify the color, bits 5-6 specify the waypoint display attribute and bit 7 is unused and must be 0. Valid color values are specified below. If an invalid color value is received, the value shall be Black. Valid display attribute values are as shown below.

posn - Position. If a D110 waypoint is received that contains a value in the lat field of the posn field that is greater than 2^30 or less than -2^30, then that waypoint shall be rejected.
7.4.12 D120_Wpt_Cat_Type
typedef struct
{
char name[17]; /* category name */
} D120_Wpt_Cat_Type;

} D800_Pvt_Data_Type;
The “alt” parameter provides the altitude above the WGS 84 ellipsoid. To find the altitude above mean sea level, add “msl_hght” to “alt” (“msl_hght” gives the height of the WGS 84 ellipsoid above mean sea level at the current position).
The “tow” parameter provides the number of seconds (excluding leap seconds) since the beginning of the current week, which begins on Sunday at 12:00 AM (i.e., midnight Saturday night-Sunday morning). The “tow” parameter is based on Universal Coordinated Time (UTC), except UTC is periodically corrected for leap seconds while “tow” is not corrected for leap seconds. To find UTC, subtract “leap_scnds” from “tow.” Since this may cause a negative result for the first few seconds of the week (i.e., when “tow” is less than “leap_scnds”), care must be taken to properly translate this negative result to a positive time value in the previous day. Also, since “tow” is a floating point number and may contain fractional seconds, care must be taken to properly round off when using “tow” in integer conversions and calculations.
The “wn_days” parameter provides the number of days that have occurred from UTC December 31st, 1989 to the beginning of the current week (thus, “wn_days” always represents a Sunday). To find the total number of days that have occurred from UTC December 31st, 1989 to the current day, add “wn_days” to the number of days that have occurred in the current week (as calculated from the “tow” parameter).
The default enumerated values for the “fix” member of the D800_Pvt_Data_Type are shown below. It is important for the host to inspect this value to ensure that other data members in the D800_Pvt_Data_Type are valid. No indication is given as to whether the device is in simulator mode versus having an actual position fix.

The “max_unscheduled_workouts” member represents the number of workouts the device can hold which do not have any occurrences (i.e. they are “unscheduled”). The “max_occurrences” member represents the number of workout occurrences that the device can hold.
As an example, suppose a device can hold 200 total workouts, 25 unscheduled workouts, and 200 occurrences. Under these circumstances, it would be appropriate to send 175 scheduled workouts, up to 200 combined occurrences of those scheduled workouts, and 25 workouts that have not been scheduled.

The value of the “track_index” member must be 0xFFFF if there is no associated track. The “program_type” member is a bit field that indicates the type of run this is. The following table describes the meaning of each bit:
