Class TemplateEngine


  • public class TemplateEngine
extends java.lang.Object
    A very simple template engine. The template engine takes input and transforms it by looking for tags in the document, and replacing them with values provided by a set of ValueProviders.

    Example of HTML template:

    <html>
    <head>
    <title>{v:title}</title>
    </head>
    <body>
    Welcome {v:name} to Simple Template Example
    <table>
    <tr bgcolor="d0d0d0"><th>Author</th><th>Title</th><th>Year</th></tr>
    <t:book>
    <tr>
    <td><a href="#">{v:author}</a></td>
    <td><a href="#">{v:title}</a></td>
    <td><a href="#">{v:year}</a></td>
    </tr>
    </t:book>
    </table>
    </body>
    </html>

    The design (although not the code) was inspired by the JByte template engine
