SFVec2dObject (X3DJSAIL, X3D Java Scene Access Interface Library)

java.lang.Object
- org.web3d.x3d.jsail.fields.X3DConcreteField
- - org.web3d.x3d.jsail.fields.SFVec2dObject

All Implemented Interfaces:

SFVec2d, X3DField
```
public class SFVec2dObject
extends X3DConcreteField
implements SFVec2d
```
This utility class provides a concrete implementation corresponding to SFVec2d X3D field type.

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 in attribute values do not pass strict XML validation.
