| 255 | |
| 256 C<IMPL::Web::TT::Document> - Документ, позволяющий строить представление по шаблону | |
| 257 | |
| 49 | 258 =head1 SYNOPSIS |
| 259 | |
| 75 | 260 =begin code |
| 261 | |
| 49 | 262 // create new document |
| 77 | 263 my $doc = new IMPL::Web::TT::Document; |
| 49 | 264 |
| 265 // load template | |
| 266 $doc->loadFile('Templates/index.tt'); | |
| 267 | |
| 268 // render file | |
| 269 print $doc->Render(); | |
| 270 | |
| 75 | 271 =end code |
| 272 | |
| 49 | 273 =head1 DESCRIPTION |
| 274 | |
| 77 | 275 C<use base qw(IMPL::DOM::Document)> |
| 276 | |
| 49 | 277 Документ, основанный на шаблоне Template::Toolkit. Позволяет загрузить шаблон, |
| 278 и сформировать окончательный документ. Является наследником C<IMPL::DOM::Node>, | |
| 279 т.о. может быть использован для реализации DOM модели. | |
| 280 | |
| 281 Внутри шаблона переменная C<document> ссылается на объект документа. По этой | |
| 282 причине образуется циклическая ссылка между объектами шаблона и документом, что | |
| 283 требует вызова метода C<Dispose> для освобождения документа. | |
| 284 | |
| 285 =head1 METHODS | |
| 286 | |
| 77 | 287 =over |
| 49 | 288 |
| 77 | 289 =item C<CTOR()> |
| 49 | 290 |
| 77 | 291 Создает новый экземпляр документа, свойство C<nodeName> устанавливается в 'C<document>' |
| 49 | 292 |
| 77 | 293 =item C<$doc->LoadFile($fileName,$encoding)> |
| 49 | 294 |
| 295 Загружает шаблон из файла C<$fileName>, используя кодировку C<$encoding>. Если | |
| 296 кодировка не указана, использует utf-8. | |
| 297 | |
| 298 =item C<$doc->Render()> | |
| 299 | |
| 300 Возвращает данные построенные на основе загруженного шаблона. | |
| 301 | |
| 302 =item C<$doc->Dispose()> | |
| 303 | |
| 304 Освобождает ресурсы и помечает объект как освобожденный. | |
| 305 | |
| 306 =back | |
| 307 | |
| 76 | 308 =head1 DOM |
| 309 | |
| 108 | 310 Документ представляет собой DOM документ, состоящий из узлов, которые представляют собой данные |
| 311 для отображения. Для форматированого вывода используется C<template>. | |
| 312 | |
| 313 В качестве элементов документа могут присутсвовать специальные объекты C<IMPL::Web::TT::Control>, | |
| 314 которые внутри содержат шаблон для форматирования собственного содержимого. | |
| 315 | |
| 316 | |
| 317 | |
| 318 Документ предоставляет ряд фнукций для работы с элементами управления. | |
| 319 | |
