S (Rythm Template Engine 1.4.1 API)

java.lang.Object
- org.rythmengine.utils.S

```
public class S
extends Object
```
A utility class providing String manipulation methods. Commonly used in template engine process.

Note all methods defined in this class is null safe. if any input is null the return value is ""

An instance of this utility is exposed to any Rythm template via TemplateBase.s() method and can be used in template source code freely. E.g.
```
  @if(s().empty(name)) { user name is empty!
 } 
```
