                   Handler<AsyncResult<Buffer>> handler)

Description copied from interface: TemplateEngine

Render the template. Template engines that support partials/fragments should extract the template base path from the template filename up to the last file separator. Some engines support localization, for these engines, there is a predefined key "lang" to specify the language to be used in the localization, the format should follow the standard locale formats e.g.: "en-gb", "pt-br", "en".

Specified by:

Parameters:

context - the routing context

templateFile - the template file name to use

handler - the handler that will be called with a result containing the buffer or a failure.

unwrap

public <T> T unwrap()

Description copied from interface: TemplateEngine

Returns the underlying engine, so further configurations or customizations may be applied.

Specified by:

Type Parameters:

T - the engine object type.

Returns:

the engine instance.
