All Implemented Interfaces:

SFString, X3DField
```
public class SFStringObject
extends X3DConcreteField
implements SFString
```
This utility class provides a concrete implementation corresponding to SFString X3D field type.

Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFString defines a single string encoded with the UTF-8 universal character set.
