Examples with TemplateManager org.thymeleaf.engine.TemplateManager used on opensource projects

Example 1 with TemplateManager

use of org.thymeleaf.engine.TemplateManager in project thymeleaf by thymeleaf.

the class AbstractStandardInliner method inlineSwitchTemplateMode.

private CharSequence inlineSwitchTemplateMode(final ITemplateContext context, final IComment comment) {

         * Notice we are ONLY processing the contents of the Comment, because we know the target inlining
         * mode will not understand the Comment (it will be textual) and we don't want it to mess around with
         * the Comment's prefix and suffix.
         *
         * Note this will only be executed in markup modes (textual modes never fire "handleComment" events),
         * so we are safe assuming the sizes of Comment prefixes and suffixes in HTML/XML.
