public interface Content

This interface can be used to create reusable content blocks for templates through Java code. When using the content block shorthand @`...` in templates, behind the scenes an anonymous class of Content is created as well. For example:

    !{var name = "world";}
    !{var myContent = @`
        Hello ${name}!
        This is a reusable content block.
    `;}

    ${myContent}
    ${myContent}

Would be the same as:

    public class MyContent implements Content {
        private final String name;

        public MyContent(String name) {
            this.name = name;
        }

        @Override
        public void writeTo(TemplateOutput output) {
            output.writeContent("Hello ");

            // User provided content, must be output escaped!
            output.writeUserContent(name);

            output.writeContent("!\n This is a reusable content block.");
        }
    }

While the above example doesn't make a lot of sense, Content can be a very powerful abstraction for complex tasks.
