Examples of org.thymeleaf.fragment.IFragmentSpec

org.thymeleaf.fragment.IFragmentSpec

Common interface for all fragment specifications.

Fragment specifications are able of extracting specific sections or subtrees from a DOM node tree, according to the logic defined at the specific implementation.

Fragment specs have multiple uses. One of them is allowing the {@link org.thymeleaf.TemplateEngine} to select a fragment of a templateto be processed (once read and parsed), discarding the rest of the template and reducing the processing effort to executing just the wanted parts. See {@link org.thymeleaf.TemplateEngine#process(String,org.thymeleaf.context.IContext,IFragmentSpec)}for more info.
