DOM refactoring
ObjectToDOM methods are virtual
QueryToDOM uses inflators
Fixed transform for the complex values in the ObjectToDOM
QueryToDOM doesn't allow to use complex values (HASHes) as values for nodes (overpost problem)

| 146 | |
| 147 =head2 BLOCKS | |
| 148 | |
| 149 =head3 INIT | |
| 150 | |
| 213 | 151 Данный блок шаблона управления выполняется один раз при создании первого экземпляра элемента управления, |
| 152 может использоваться для формирования заголовочной части документа, скрипта подключающего ajax модули | |
| 153 при необходимости и т.п. | |
| 181 | 154 |
| 155 =head3 CTOR | |
| 156 | |
| 157 данный блок выполняется каждый раз при создании нового экземпляра элемента управления, при этом переменная C<this> | |
| 213 | 158 указывает на эземпляр элемента упарвления. Данный блок можно использовать для инициализации свойств элемента |
| 159 управления. | |
| 181 | 160 |
| 161 =head3 RENDER | |
| 162 | |
| 213 | 163 Данный блок выполняется при вызове метода C<Render()>, вывод данного блока и есть результат отображения элемента управления. |
| 164 Если в шаблоне нет блока C<RENDER>, то сам шаблон считается таковым. | |
| 187 | 165 |
| 166 =head2 TEMPLATE VARS | |
| 167 | |
| 168 Каждый шаблон имеет собственное пространство имен, унаследованное от пространства имен фабрики элементов (которая в свою очередь наследует контекст документа). | |
| 169 В шаблоне могут определяться новые переменные, которые разделяются между блоками. Также доступны стандартные переменные | |
| 170 | |
| 171 =over | |
| 172 | |
| 173 =item * C<this> ссылка на объект элемента управления | |
| 174 | |
| 175 =item * C<component> ссылка на текущий шаблон, устанавливается автоматически в методе C<Template::Context::process>. | |
| 176 | |
| 177 =item * C<template> ссылка на шаблон элемента управления, для совместимости с C<TT> | |

| 184 | |
| 185 =item * C<[get]context> | |
| 186 | |
| 187 Контекст элемента управления, хранит пременные шаблона. Наследуется от контекста фабрики элементов управления, который | |
| 188 наследуется от контекста документа. | |
| 189 | |
| 190 =item * C<[get,set]template> | |
| 191 | |
| 192 C<Template::Document> Шаблон элемента управления. | |
| 193 | |
| 194 =item * C<AUTOLOAD> | |
| 195 | |
| 196 Для удобства работы с шаблоном, элементы управления предоставляю доступ к своим свойствам через метод C<AUTOLOAD>. | |
