型チェックについて †
- Wicketは、マッピング先のJava型に従って適当に型変換と型チェックをしてくれる
| Java型 | 入力可能な値 | 備考 |
| bool | true / false / yes / no / on / off | |
| char | １文字 | サロゲート文字は入力エラーになる |
| byte | 127〜-128 | 16進数、指数表現は不可 |
| short | 32767〜-32768 |
| int | 2147483647〜-2147483648 |
| long | 9223372036854775807〜-9223372036854775808 |
| float | 3.4028235E38〜1.4E-45 | 指数表現可。1.0E+10は入力エラーになる。1.0E10、1.0E-10はＯＫ。(※1) |
| double | 1.7976931348623157E308〜4.9E-324 |
| Date | 日付フォーマットは、DateTextField?で指定可(※2)。無指定時はブラウザのロケールによる。 | ブラウザのローケールが日本語の場合、 MM/dd/yyyy が使われる |
- ※1…浮動小数点型へのマッピングをすると適当に丸められてしまうので、厳密にやりたければ String入力項目にして自前で変換すべき
- ※2…Wicket 日付の入力補助#format
