Teedaネスト対応 - akiraneko’s blog

これで実験してから一年半ぐらい経過していますが、組んでみました。

	data3Dto = new Data3Dto();
	data3Dto.data5 = "DataText5";
	data3Dto.data6 = "DataText6";
	data3Dto.data2Dto = new Data2Dto();
	data3Dto.data2Dto.data3 = "DataText3";
	data3Dto.data2Dto.data4 = "DataText4";
	data3Dto.data2Dto.dataDto = new DataDto();
	data3Dto.data2Dto.dataDto.data1 = "DataText1";
	data3Dto.data2Dto.dataDto.data2 = "DataText2";

こんな感じのデータが

<span id="data3Dto_data5">data3Dto_data5</span><br />
<span id="data3Dto_data6">data3Dto_data6</span><br />
<span id="data3Dto_data2Dto_data3">data3Dto_data2Dto_data3</span><br />
<span id="data3Dto_data2Dto_data4">data3Dto_data2Dto_data4</span><br />
<span id="data3Dto_data2Dto_dataDto_data1">data3Dto_data2Dto_dataDto_data1</span><br />
<span id="data3Dto_data2Dto_dataDto_data2">data3Dto_data2Dto_dataDto_data2</span><br />
<span id="data3Dto_data2Dto_dataDto_data3">data3Dto_data2Dto_dataDto_data3</span><br />

こんな感じで利用できます。
最後のdata3Dto_data2Dto_dataDto_data3はプロパティーがないので、データが入らない状態ででます。標準だと例外エラーになるのでここのチェックが一番面倒だと思います。

以下パッチですが、

http://akira.info/labs/NestTeeda/teeda.patch
http://akira.info/labs/NestTeeda/teedaNest20110224.lzh

ここにパッチと、サンプルで動いているプロジェクト起きました。
Eclipseのパッチはなんかおかしい。。。ひとつだけ適応されないところがでてきています(涙)

もう少しテストを書く必要があるけれど、普通にデータ表示するだけだったらこれでいいのかな？
性能実験やっていないので、もう少し速度的な最適化はできるきがします。
