This utility class provides a concrete implementation corresponding to SFVec2f 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
Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFVec2f is a 2-tuple pair of SFFloat values. Hint: SFVec2f can be used to specify a 2D single-precision coordinate. Warning: comma characters within singleton values do not pass strict XML validation.
