Class SFVec2d

java.lang.Object
org.web3d.x3d.jsail.fields.X3DConcreteField
org.web3d.x3d.jsail.fields.SFVec2d
All Implemented Interfaces:
SFVec2d, X3DField
public class SFVec2d extends X3DConcreteField implements SFVec2d
This utility class provides a concrete implementation corresponding to SFVec2d 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). SFVec2d is a 2-tuple pair of SFDouble values. Hint: SFVec2d can be used to specify a 2D double-precision coordinate. Warning: comma characters within singleton values do not pass strict XML validation.
