061:         * A {@link TemplateLoader} that uses a Map with Strings as its source of 
062:         * templates.
063:         *
064:         * In most case the regular way of loading templates from files will be fine.
065:         * However, there can be situations where you don't want to or can't load a
066:         * template from a file, e.g. if you have to deploy a single jar for 
067:         * JavaWebStart or if they are contained within a database.
068:         * A single template can be created manually
069:         * e.g.
070:         * <pre>
071:         *   String templateStr="Hello ${user}";
072:         *   Template t = new Template("name", new StringReader(templateStr),
073:         *               new Configuration());
074:         * </pre>
075:         * If, however, you want to create templates from strings which import other 
076:         * templates this method doesn't work.
077:         *
078:         * In that case you can create a StringTemplateLoader and add each template to 
079:         * it:
080:         * <pre>
081:         *   StringTemplateLoader stringLoader = new StringTemplateLoader();
082:         *   stringLoader.putTemplate("greetTemplate", "<#macro greet>Hello</#macro>");
083:         *   stringLoader.putTemplate("myTemplate", "<#include \"greetTemplate\"><@greet/> World!");
084:         * </pre>
085:         * Then you tell your Configuration object to use it:
086:         * <pre>
087:         *   cfg.setTemplateLoader(stringLoader);
088:         * </pre>
089:         * After that you should be able to use the templates as usual. Often you will
090:         * want to combine a <tt>StringTemplateLoader</tt> with another loader. You can
091:         * do so using a {@link freemarker.cache.MultiTemplateLoader}.
