## Class TemplateEngine

- java.lang.Object

    FreeMarkerTemplateEngine, HandlebarsTemplateEngine, JadeTemplateEngine, MVELTemplateEngine, PebbleTemplateEngine, RockerTemplateEngine, ThymeleafTemplateEngine

      public class TemplateEngine
      extends Object

  A template template uses a specific template and the data in a routing context to render a resource into a buffer.

  Concrete implementations exist for several well-known template engines.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.

  - ### Method Detail

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`

    - #### equals

          public boolean equals(Object o)

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### getDelegate

          public TemplateEngine getDelegate()

    - #### render

          public void render(JsonObject context,
                             String templateFileName,
                             Handler<AsyncResult<Buffer>> handler)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use
        `handler` - the handler that will be called with a result containing the buffer or a failure.

    - #### render

          public void render(JsonObject context,
                             String templateFileName)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use

    - #### rxRender

          public Single<Buffer> rxRender(JsonObject context,
                                         String templateFileName)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use
      Returns:

    - #### clearCache

          public void clearCache()

      Clears any internal caches used by this engine. For most engines this means clearing the vert.x cache, implementations that do not use vert.x as a cache should clear their own cache.

    - #### render

          public void render(Map<String,Object> context,
                             String templateFileName,
                             Handler<AsyncResult<Buffer>> handler)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use
        `handler` - the handler that will be called with a result containing the buffer or a failure.

    - #### render

          public void render(Map<String,Object> context,
                             String templateFileName)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use

    - #### rxRender

          public Single<Buffer> rxRender(Map<String,Object> context,
                                         String templateFileName)

      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".
      Parameters:
        `context` - the routing context
        `templateFileName` - the template file name to use
      Returns:

          public <T> T unwrap()

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

    - #### newInstance

          public static TemplateEngine newInstance(TemplateEngine arg)
