render

public void render(String templatePath,
                   Object root,
                   Writer out)
            throws freemarker.template.TemplateException,
                   IOException
Throws:
freemarker.template.TemplateException
IOException
See Also:
render(String, Locale, String, Object, java.io.Writer)

render

public void render(String templatePath,
                   Locale locale,
                   String i18nBasename,
                   Object root,
                   Writer out)
            throws freemarker.template.TemplateException,
                   IOException
Renders the given template, using the given root object (can be a map, or any other type of object handled by MagnoliaContentWrapper) to the given Writer. If the root is an instance of a Map, the following elements are added to it: - ctx, the current Context instance retrieved from MgnlContext - contextPath, if we have an available WebContext (@deprecated) - defaultBaseUrl, as per Server.getDefaultBaseUrl()

Throws:
freemarker.template.TemplateException
IOException
See Also:
ServerConfiguration.getDefaultBaseUrl()

render

public void render(Reader template,
                   Object root,
                   Writer out)
            throws freemarker.template.TemplateException,
                   IOException
Renders the template read by the given Reader instance. It should be noted that this method completely bypasses Freemarker's caching mechanism. The template will be parsed everytime, which might have a performance impact.

Throws:
freemarker.template.TemplateException
IOException

render(Reader, Locale, String, Object, Writer)
