All Implemented Interfaces:: SFDouble, X3DField

public class SFDoubleObject
extends X3DConcreteField
implements SFDouble

This utility class provides a concrete implementation corresponding to SFDouble X3D field type.

Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFDouble is a double-precision floating-point type. Array values are optionally separated by commas in XML syntax. See GeoVRML 1.0 Recommended Practice, Section 2.3, Limitations of Single Precision for rationale.
