dw.template
Class Velocity
Object
dw.template.Velocity
This class renders an Apache Velocity template. For Velocity template syntax, see Velocity 1.7.

The render() methods identify the template to render from:

  • a template file name, which is resolved in the Dynamic WebDAV file location for the current site. Template file names must end with either '.vm' or '.vs'.
  • a dw.io.File object, which can point to any file system location that is accessible from a script
  • a string that holds the template content directly
Note: Files included from an ISML template (either via #parse or #include) are always resolved in the Dynamic location, and it is not possible to provide an absolute path.

On the target side of rendering, by default the render() methods write to the current response writer. When needed, a dw.io.Writer can be supplied as a target.

Parameters for rendering can be passed as a single object holding the parameters as properties.

To create a URL, pass the URLUtils class.
To access localized strings, pass the Resource class: 


 var urlUtil = require('dw/web/URLUtils');
 velocity.render("$url.abs('Foo-Bar','cgid',$res.msg('key')", {'url' : urlUtil, 'res' : dw.web.Resource});
The complete set of VelocityTools are provided to the template. You can use the tools to escape dynamic data, format text, and for other common tasks.

Template files are cached for different amounts of time, depending on the instance type.

This class does not have a constructor, so you cannot create it directly.
