Class EqualsHelper

java.lang.Object

org.trimou.handlebars.BasicHelper

org.trimou.handlebars.BasicSectionHelper

org.trimou.handlebars.EqualsHelper

All Implemented Interfaces:

ConfigurationAware, Helper

public class EqualsHelper
extends BasicSectionHelper

Renders a block if the first param does/doesn't equal to the second param (by means of Object.equals(Object)).

 {{#isEq item.status Status.ACTIVE}}
   It's equal!
 {{/isEq}}
 

If only one param is defined, the object at the top of the context stack is used:

 {{#with foo}}
  {{#isEq Status.ACTIVE}}
      It's equal!
  {{/isEq}}
 {{/with}}
 

If any object is null, the block is not rendered.
