Class MFString

java.lang.Object
org.web3d.x3d.jsail.fields.X3DConcreteField
org.web3d.x3d.jsail.fields.MFString
All Implemented Interfaces:
MField, MFString, X3DField
public class MFString extends X3DConcreteField implements MFString
This utility class provides a concrete implementation corresponding to MFString 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). MFString is an array of SFString values, each "quoted" and separated by whitespace. Individual SFString array values are optionally separated by commas in XML syntax.

Related field object: SFString
