MFColorRGBAObject (X3DJSAIL, X3D Java Scene Access Interface Library)

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

All Implemented Interfaces:

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

Note that SFColorObject provides a variety of color constants.

Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). MFColorRGBA specifies zero or more SFColorRGBA 4-tuples. Each color value is an RGBA 4-tuple of floating point numbers in the range 0.0 to 1.0. Alpha (opacity) values = (1 - transparency). The default value of an uninitialized MFColor field is the empty list. Individual SFColorRGBA array values are optionally separated by commas.

Related field object: SFColorRGBAObject
