- javax.servlet.jsp.tagext.TagSupport
- - org.appng.taglib.If

All Implemented Interfaces:

```
public class If
extends javax.servlet.jsp.tagext.TagSupport
```
Processes the taglet's body if the given condition evaluates to be true. In the condition, any request parameter can be used. Since the condition is evaluated by an ExpressionEvaluator, the JSP expression language needs to be used.
