Interface Lambda<C,​O>

  • Type Parameters:
    C - The lambda context.
    O - The lambda output.

    public interface Lambda<C,​O>

    When the value is a callable object, such as a lambda, the object will be invoked and passed the block of text. The text passed is the literal block, unrendered. {{tags}} will not have been expanded - the lambda should do that on its own. In this way you can implement filters or caching.


     {{name}} is awesome.
     Map hash = ...
     hash.put("name", "Willy");
     hash.put("wrapped", new Lambda<String>() {
       public String apply(Scope scope, Template template) {
        return "" + template.apply(scope) + "";


     Willy is awesome.
