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.

Template:

 {{#wrapped}}
 {{name}} is awesome.
 {{/wrapped}}
 

Hash:

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

Output:

 Willy is awesome.
