All Implemented Interfaces:
MField, MFVec4f, X3DField

public class MFVec4f extends X3DConcreteField implements MFVec4f
This utility class provides a concrete implementation corresponding to MFVec4f 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). MFVec4f is zero or more SFVec4f values. Individual singleton SFVec4f array values are optionally separated by commas in XML syntax.
