Class MFVec2f

java.lang.Object

vrml.Field

vrml.MField

vrml.field.MFVec2f

All Implemented Interfaces:

Cloneable

public class MFVec2f
extends MField

VRML JSAI type class containing multiple vector2f fields.

Internally, the class stores the values as a single, flat array so that is the most efficient method to use to avoid reallocation. All methods make internal copies of the values.
