All Implemented Interfaces:

SFString, X3DField

public class SFString
extends X3DConcreteField
implements SFString

This utility class provides a concrete implementation corresponding to SFString X3D field type.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes.
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.
